Humans have burned incense since ancient times for reasons that range from the practical to the divine. To aid in these rites, various cultures have created exquisite censers and housings for the burning, smoke-emitting biotics. In this episode of Stuff to Blow Your Mind, Robert and Joe consider some outstanding examples from the history of incense, including the incense clocks of China and swinging thuribles of Catholic tradition.
Welcome to stuff to blow your mind. Production of my heart radio. Hey you, welcome to stuff to blow your mind. My name is Robert Lamb and I'm Joe McCormick and we're about to venture into, I think, a couple of episodes on the topic of incense and I was looking around for some fun quotes related to incense and we're gonna get to some fun quotes and some mystical quotes related to incense, but I was really enraptured by a particular quote from Shaquille O'Neal uh, Shack himself, uh, that I read without any initial context. The quote is incense books. Just weird, which which raises so many questions, especially since I really don't know a whole lot about about sports and the life of shack and so forth. I I played shack Fou the the old video game back in the day, the first one, but outside of just shacks General Um ever present media power and his appearance all throughout media, I don't know much about him. Uh. So I had to research this one a little bit and not certain, but I think this is a quote from shack talking about his former coach Phil Jackson. I believe the situation is that during the early two thousand's, Jackson would have the Lakers meditate before their games, and I think he also assigned various texts for his players to read. So maybe our basketball fan listeners out there can chime in on this topic. Oki Doki, I have absolutely nothing to offer here. I know I have almost zero shack knowledge. So we've discussed the human mastery of Fire Multiple Times on the podcast. How it enabled us to externalize our digestion and master cooking, how it enabled us to illuminate the dark and somewhat free ourselves from the shackles of night, how it enabled us to master the use of minerals and ultimately venture into the world of Alchymy and chemistry. Now, on the subject of smoke itself. We have discussed the use of smoke in long distance communication, but the use of incense, the burning of specific biotic materials to produce pleasing and or masking fragrances, as well as the visual splendor of smoke, this is an area I don't think we've really considered before. So what? What? What got you going on, incense man? I think interestingly enough, I was on the front porch. It had gotten cool enough to work outside, have my laptop out there, but I had some Anti Mosquito UH incense burning. Not not the spiral kind that will reference in a bit, but one of these more modern situations where you have a little gas pod that's put in the bottom of the machine and then you have a little cab that has a certain chemicals on it that you slide in and then that Burns and it creates uh, some nice, pleasant looking whiffs of of Grace Molk that also keep the mosquitoes at bay at least a little bit. So one thing I gotta Start With an addressing incense uh is that I mistakenly used to think that incense was one unique substance, like it was the product of one plant or something, but apparently that's not true and it's also not a consistent recipe for a combination of products that that applies to all incense around the world. Instead, I think we should say incense is a class of substances right. It's like any organic material or combination of organic materials that you burn in order to release a fragrant smoke. So what goes in your incense and one culture might be totally different than what goes in in another and and even within a culture you might use different substances. That's right. Yeah, various traditions will have different blends, different materials and yeah, sometimes you're talking about, uh, some sort of dried substances, other times it's formed into an incense stick. Certainly we have cones. Uh, they're also oiled. I mean there's a a wide spectrum of substances, though I would say generally we're taught not talking about things that are intended to be directly inhaled. Generally we're talking more about an ambiance in a room, though they of course, are gonna end up inhaling some of that, but it is contributing to the atmosphere. It is not, uh, something that one is necessarily consuming, right. So the English word incense traces back through the French to the late Latin Word Incense Um, just meaning that which is burned. It's a thing that you burn, and this is related to the Latin verb incendiary, which means to set something on fire, to light on fire. So it's something that you burn to produce an aromatic smoke, especially a sweet smoke, according to a lot of early sources. So while incense is a class of substances. Uh. There are some specific plant products that are especially significant in the history of the incense trade, and a couple that really stand out to me because of, you know, all my received Bible stories as a child. I think will be familiar to many other listeners. This would be the references to incense in the story of the birth of Jesus in the Gospel of Matthew. So in this story it says that when Jesus was born, uh there were wise men, that this is a translation of the Latin Magi or the Greek Meg Oi, wise men bringing three gifts to honor the birth of Jesus, that they show up and these gifts are gold, frankincense and myrrh. Now, first of all I want to do one of my little patented uh Joe McCormick Bible fact drops. Did you know that the Bible does not actually say there were three wise men? The story of the wise men bringing gifts uh at the birth of Jesus appears only in the Gospel of Matthew. And here's what it says. So this is from the N RSV quote. In the time of King Herod, after Jesus was born in Beth him of Judea Magi from the east came to Jerusalem, asking where is the child who has been born the king of the Jews, for we observed his star in the East and have come to pay him homage. So that's it. It's just Maji, just a plural. Nown now there has been an ocean of ink spilled over how best to interpret the word Magi. Who did the author have in mind when the story was written? The theory that seems most convincing to me is that this is probably a reference to Ptarthian or Persian Zoroastrian priests who were thought to be very adept at reading portents in the stars, which is why the word Magi is sometimes translated as astrologers. But anyway, that's all it says. Says Magi came or MEG OI came. Uh, not how many of them there were, but the traditional interpretation that there were three of them is probably derived from the fact that it does say they brought three gifts, and those gifts again are gold, frankinsence and murder. So we know what gold is, but what are those other two things? Well, actual relief, Frankincense and Mr are both types of incense. They are resins or chunks of hardened gum or sap from two different types of related trees in the Burceray C I family uh and the Burceray C I family uh. These are arid or semi arid tree like plants that I think are typically associated with growing in the Arabian Peninsula and on the on the Horn of Africa. And so these two incense resins, along with gold, are probably used in the story from the Gospel of Matthew because they're supposed to show that the Magi or the Magi recognize Jesus as a king, as a king foretold in the stars, because Franken sits and Mur like gold, are expensive luxury items there. They're they're associated with with power and with religious significance, that they were used in religious rituals all throughout the ancient Mediterranean and also to perfume the itch such, as you know, in a burial ritual for a king. Now I've seen enough imagery, Christian imagery of the three kings uh, to you know, to to know that you know, generally they are depicted as holding some sort of special box that contains the Frankensense and the Murr and of course I've I've seen images of frankensense itself. But I still have to say, like, when I think of the three kings bringing gold, Frankensense and Murr, I hear frankensense and I still imagine Frankenstein's monster. Um, he said, at least back there, lurking in the back of my mind, even as I'm putting together this major scene in my head right there with you. I I always made that connection when I was a kid. It's like you got Frankenstein, frank and Berry cereal and Frankensense the gift to Jesus, and I don't know what that is because they never explained when I was a kid. I think one time actually, somebody did explain that, uh, that mirror was used for uh, it was used in its like essence form or oil form to anoint Berry Oles of the dead, and I was like, well, that's a morbid gift to give a baby. It's like here's something that we will put on you when you die. But again, I think it's supposed to be something that is expensive and royal and and holy and shows that, you know, they recognize that the stars have foretold. This is going to be a king yeah, and I think these are all things to keep in mind as we start, as we eventually discuss how how incense factors into different cultures and different belief systems, like what it means to burn this sacred substance that creates a special pleasing odor. I actually found a fascinating article about that that I think we're going to get into more in part two of the series. But before we move on from frankensince and Mura, I did want to add a few more facts descriptive about their what they're like and how they were used in the ancient world. And Uh, this is coming from another interesting article I was reading. This was an eon magazine by a University College London anthropologist named Timothy Carroll, and the article was called Franken since Murr both holy and heretical. And so there is a background section where where Carol here is describing what these these smells are like. It's kind of hard to you know, we can't make you smell it through the Internet here, so unfortunately we can't give samples. But if you've never smelled them before differentiated them. Frankensense is known to have a kind of woody or what he calls a warm spiced smell. So I'm imagining that is in some way roughly similar to the warm spices like, I don't know, cloves, allspice, cinnamon and that kind of thing, whereas Carol says that mirror is typically said to smell like rose or maybe like Basil, but also is sometimes said to have a kind of bitter aroma, and if you think about the kind of bitter back note to the smell of a rose, that makes sense to me. An interesting thing about the origins of the word Frankensense. Uh so you associated with Franken Stein, but actually what what frankensense means is, uh, the refix. Frank there is just a word that archaically means like high quality or pure. So Frank instence basically means like pure incense or really good incense. Another distinction is that I said both of these were forms of incense, and they are, but frank instence, I think, is almost always used as a as a type of burned incense, so you would burn pellets of it to make a smoke, whereas mirror has a lot of different preparations. Sometimes it is burned as incense other times people will make like an oil infusion out of it and use that to like anoint people, to you know, place upon their heads for religious purpose or at a burial or something like that. But Carol talks about how these substances were not just for the religious purposes that we're going to get into in more detail. They were also believed to have like practical benefits. He points out that, as we've talked about on the show before, a lot of in the ancient world there was a lot of association between disease and bad smells. So aromatic substances were used throughout the ancient Mediterranean to cleanse bad air that was thought to somehow be associated with disease and also to drive away vermin like rats. Okay, so, so, functionally at the very least, amasking odor, but within the like the crude belief systems of of the day regarding infection and disease, they're cleansing, they're actually helping to protect you from illness and well, I'm not sure Howard to rule the prevention of rats creeping around. I mean I think you could say that to various extents aromatic smokes are effective at driving away especially insects. Yeah, I don't yeah, but I don't know about the rats. I'd need to see more. More data is required on that. But there were all these alleged medical uses of these fragrant substances, like Frankensin Sen Mur Carol points to the writings of an ancient Greek physician named Pedanius Dioscorides, who lived from forty to nineties Ce and speaking about Murr specifically, diascordes, says, quote, rubbed on with the flesh of a snail, it cures broken ears and exposed bones, as well as pus in the ears and their inflammation, with meconium castoreum and glaucium. It is rubbed on vericose veins with Cassia and honey. Very good, very good. Some key substances in there, some of which will come back up again, and he mentioned some other uses too. It is thought to have to be able to help regulate sleep, blood flow, menstruation, all kinds of things. So this is the Murror is kind of shaping up like a cure, all like it has some kind of religious significance. It will, it will mask the odors of death, it will make you seem like a king and it will also, allegedly, like, cure all these various diseases or regulate the processes of the body. But to come back to the idea of incense more generally again, we're talking about a a class of substances that you would burn in order to produce an aromatic smoke. That's right, and and certainly fragrant woods, herbs, oils other such substances. They can be added to many different heat sources, many different flames, including flames that are primarily used for illumination or cooking, Um like on. On the subject of cooking, I don't really barbecue much anymore. When I do cook something, I use a gas grill, but I remember growing up when you do the charcoal grill and occasionally cooking certain cuts of meat, it was desired to get like some hickory branches to add to the coals underneath, uh, and so you know, there are various things like that one, of course, can do within say, a culinary tradition. Yeah, and smoking meat has multiple effect. I mean, on one hand it's just pleasurable. People like the taste of of smoke, but also it has preservative effects, yes, but it's also a rich global tradition of creating specialized sensors or other artifacts does signed and built exclusively for burning incense of some sort. Now a lot of these devices are tied into practices that involve the burning of incense for pleasure and or religious purposes, and we'll get into many of those in a bit. But I wanted to touch a little bit on the idea of of of practical incense burning, functional instance burning kind of like we're talking about earlier to drive the rats away at the bad air UM. And coming back to my earlier example of of of mosquito repellent, because really the first place my mind went when I started thinking about this, in part because I was keeping mosquitoes away with with special smoke at the time, is the humble mosquito coil. Everyone, I think it's probably seen this usually green. It's a coil, it's it's essentially an incense you start burning the the outer edge of the coil and it slowly burns and spirals in towards the center. Generally this is the coil itself. Contains Pyrethrum, which is naturally occurring, and acticide. UH, there may be some other ingredients in there and you're generally talking about six inches length coiled up in one of these, and it will take up to about twelve hours to burn through. I don't have a lot of direct experience with these that I was just looking up some general stats about them. It's apparently a Japanese invention of the eighteen hundreds uh that that of course, really takes off once you have mass production capabilities in place for it. It's a design that effectively allows you to have a super long incense stick that will burn for a long time but also doesn't take up a lot of space, because imagine if you had, instead of it being in a spiral, it was just like just a long incense stick. It could kind of be a pain to to lay out somewhere that if it covered the entire length of the picnic table, for example, that wouldn't be as as cool of an experience. Now again, I don't know exactly how dependable the idea of up to twelve hours is. I don't know what affects that rate of consumption, but it does bring to mind this really and this is where I really got interested in the topic of Incense. Is that okay? You can look at the basics here. If it takes x amount of time to burn through an incense stick or an instant spiral, then perhaps that rate of change can be used to measure time. And Uh and yeah, this is a whole area of combustion based timekeeping and there are a number of things you can loop under this heading. There's, of course, the candle clock, which makes use of the gradual rate of change in a burning candle. We see these in the traditions and traditions of the East, West and Middle East, with a council in Chinese writing going back, I believe, as far as the sixth century CE. And then there are also oil lamp clocks. Now I think these only go back a couple of centuries, in part I'm guessing, because you need a dependable way of making the decrease in oil Um visual, you know. So that's gonna be harder with some of the oil lamp constructions of old. And so some of the examples that were coming up from me when I was researching this sort of eighteenth century designs, and they're really beautiful looking, but of course they involve a lot of elegant metal and glass. But the incense clock, UH, yeah, this takes us into Chinese traditions, and before I get to the invention itself, I wanted to share some some some neat insight about the role of incense in Chinese culture, as I think it'll all be worth keeping in mind as we take the additional step and considering incense as a timekeeping measure and also generally, I think flows with some of these larger and even global ideas about incense. I was reading Stuart's Sergeant's two thousand and one article from the Journal of the American Oriental Society titled Wanting Jen's incense of awareness, and while it largely deals with specific lines from the poetry of this Song Dynasty calligrapher, painter and poet who lived ten forty five through eleven oh five, it also covers the role of incense in Chinese culture in general at this time. and Um, I'm not going to skip over the translated poetry either, because it's the paper points out. He's very much leaning into the analysis of how the ritual use of incense affects one's state of mind. So here, here's, here's the first bit of poetry from wanting gin. A sense of peril like wandering ten thousand fathoms, high impatient desires engender the five weapons within. I lean on the arm rest with a single strand of incense, the numenous ESTRADE. This is a spiritual platform, or Dais Dallas de Terminology for the mind. Um, the numinous estrade is clear, empty and bright. Okay, so it sounds like he's describing an association between burning a strand of incense and having a kind of clear or elevated state of mind. Yeah, yeah, overcoming the fears and anxieties within by being able to clear mind, focusing on this, on this smoke, and in this it's interesting because this this seems to be focusing as much or more on the visual of the smoke, which I think is is easy to overlook, but I mean not if you guess, if you're really into incense, but like watching the smoke from incense rise and curl through a room. I mean it's it's it's instantly captivating. Well, yeah, a lot of the writings about incense really emphasized the smell and that does seem to be, you know, the primary sense that's engaged by it. But when you watch the smoke, I think that also brings in a lot of the ideas of I don't know the kind of ideas about religion or consciousness that are associated with it. It has to do with watching the smoke rise up into the sky and dissipate, which, on one hand, I think is a reason why the burning of incense or the burning of things in general, was often assumed to be a way of communicating with the Gods, you know, if the Gods live up above and the skies. I mean, not every belief about God's is like that, but many people believe the gods are up in the sky and the smoke rises up to them. So it's a way of reaching them with something you do. But then the other thing is like the it's it's an act that that you can kind of like watch have a consequence that then eventually disappears, like the way that the thing burns and then the smoke dissipates in front of your eyes is, uh, I don't know, some kind of significant transformation or symbol of ephemerality. Yeah, I I saw the line drawn in different sources between, uh, the the original archaic burning of sacrifices, burnt offerings, and the use, even the modern use, of incense, so as whereas one in ancient times may have burnt them, you know, the carcass of a bull or other sacrificial animal, uh, the the this would be a version of that. Instead of burning the animal, burning the remains of the animal, burning this sacred, sweet smelling substance. Oh, that's not even a connection that you have to like hypothesize, like, thinking back on it, the connection was made by by some ancient really jens themselves. Like, for example, if you look at the Hebrew Bible, there's like the first chapter of the book of Leviticus. Uh, the Lord is giving instructions to Moses on how to perform sacrifices of livestock, and this involves, you know, they'll say, you bring in the bull and you do this and you do that, and then a few verses later, at the beginning of chapter two, it says if somebody's making a grain offering instead of an offering of livestock, you need to burn incense with the grain. I'M gonna come back to that in part two when we discuss the idea that God or the Gods do enjoy smells. All right, well, let's let's go back into the poetry of lunch Gen here. UH, here's another one. That's that's really good. Midday Meal Birds Peer at the dais, sitting in peace. The Sun passes the steps. Vulgar atmosphere has no way to come near. The smoke drifts up and forms a massed defense. Now the vulgar atmosphere is not just like the stink here. This is apparently, according to the author, this is referring to like the vulgar world itself. Um, the in the vulgar atmosphere of this world, again setting aside one space, one sacred space, from the rest of reality. Now here's another one. This one comes back to snails as well as honey. Stone honey transforms snails armor. In quint's juice is boiled aloes wood from the potion sensor. A lone smoke rises. Facing this scene, I shiver with awe. Okay, that may sound a little cryptic. So in the paper sergeant explains this. That the first line here talking about stone honey transforming the snails armor. Uh, it sounds cryptic, but this is a reference to the manufacture of a particular incense of the day. Then included the operculum of a snail's Shell. This is like the like the LID. Uh that I think that's sometimes described as looking like a like a shriveled black ear, human ear. Um. It's treated with wine or honey before it's used in this process. And then the potion, he explains, is a vessel for burning incense that was introduced in the Hon Dynasty. That has a top shaped like the sacred mountain of Mount Po Rising out of the sea. And these, these are quite beautiful. Definitely look these up. Uh. They're sometimes referred to in English as hill sensors and, uh yeah, they're just absolutely beautiful, because the mountains are often depicted. The peaks of the mountains are are kind of flame like, kind of water like. It has this very, you know, it mystical appearance to it. It's because this is not just a this is not a mundane mountain, this is a celestial mountain. This is the place where the Gods live. And and also there's kind of like an egg like quality to it, especially towards the bottom. Uh, it's it's they're they're quite beautiful. Right. Here's another bit of poetry twisting and turning. The business of the incense is over thick and the it sticks to the books and paintings, who can come into my room take off your worldly shackles. Now this one I particularly love because it's basically the shock quote from the beginning of the episode. Incense books just weird. It brings to mind like detachment in the learned man's study, like this is where my books are, my paintings, and the smell of incense, like this is my space. So this is just weird in a positive way. Yeah, yeah, that's the way I'm I'm uh interpreting or applying the shock quote like, and I guess I'm thinking back to some of the various Chinese poets and writers that we've discussed in the past who are known even during the day for their weirdness, like their elongated finger nails and and so forth, their fascination with with the strange and the bizarre, like you know, those are the those are the souls I really connect with. So I'm like, Yeah, incense books and weirdness. For instance, Lee, who comes to mind, a Tang poet who lived seven ninety through sixteen. Uh, we we've covered some of his writings on the show before. He had this wonderful line that goes owls that have lived a hundred years turned forest demons laugh wildly as an emerald fire leaps from their nests. This is a stupid comparison. I don't know why that always makes me think of like strawberry alarm clock. Oh, I didn't even make the connection incense and peppermints. Than all right. Now. The next bit of poetry that Sergeant Brings Up, that that I thought was worth mentioning here, goes as follows. Pheasant tail fans cover the sound of whips. A golden censor brushes against the great purity. Your ranks are near, you smell the incense sooner and by the time you returned you had mastered it. Okay, so this quote is referring to smelling the special incense Um all the emperor in the imperial capital Um, which of course, the imperial capital. This also has celestial associations because of course the the emperor himself, has a has a divine connection in these traditions. And the whips that are mentioned here, that's those are the whips clearing the way for the emperor's procession. So I love how this it paints a nice picture, or well, maybe not a nice picture. It paints a distinct picture of, yeah, here's the sound of whips giving way to the pheasant tail fans, and then here's the burning of this very special incense. And Uh and and then there's this idea that, yeah, you can smell it and then you can potentially master it. And Uh, and this is something that sergeant brings to mind here as well. Quote Huangting Jin, close enough to the imperial entourage or the high officials to get a whiff of the court incense, is expert enough to be able to go home and duplicate it on the basis of what his nose has analyzed. Oh, he's like the guy in that book perfume. Yeah, they're. There are other like bits of poetry from this guy where he talks about like the craving of Incense. Like this is a guy who liked his incense. But, but, but, all these various examples. Um, sergeant breaks down the uses of of incense that are highlighted in his poetry and he he singles out ten of them. Some of them are kind of closely related, but I'm going to roll through them real quick. Number One, to aid in meditation, blocking external disruptions, to a barrier against the vulgar world and an outdoor scene. Uh number three, the composite of its ingredients and an awe inspiring phenomenon for a baffler against the vulgar world and an indoor scene, a kind of connects to two. Five, a token of an interpersonal relationship, interesting for the straddled social barrier. Number six, the product of another person's skill. Uh number seven, an agent to defeat the power of sense objects in another person's life. ATE, an object in a scene that has a mood but no apparent message. Nine, a sign of political status as well as the other person's technical skill, again, being able to duplicate that Special Imperial Incense that you've caught a whiff of. And then also as an attribute of enlightenment. Uh So, I like these are all interesting to keep in mind as we move move forward with this, with this upcoming example from Chinese culture, but also I think some of these can be applied, if not all of these can to be applied to varying degrees, with other cultural traditions of incense as well. I mean, it seems like a number of these are oriented around creating a kind of separation or spirit of difference, whether that is uh, sort of putting yourself in a in a mind space of peace and disconnection from the profane world, or in the idea of even just like straight up class like you, you are a rich and powerful ruler. Thus you are surrounded by incense and that sort of marks you as special and different. Yeah, yeah, you create a different atmosphere around you. And a lot of this also applies to just every day uses of incense. Today, like some people when they're writing, they like to burn a little incident. Certainly if someone is exercising or or practicing yoga or meditation, they may burn some incense as well. And Uh, you know, that can also have practical uh purposes as well, especially like an exercise class. Exercise, especially group exercise, can can have a certain effect on odors in the room and you can mask those odors with incense. So I mean it's it's kind of UH double per dual purpose there. Oh, it's the it's the environmental equivalent of don't have time for a shower, better spray the armpits. I don't know, that sounds more like the vulgar world to me, but I guess it depends on the incanse. I'm not advocating that by the way. I mean, though, it does bring up an interesting point. Is something maybe we'll have to explore in another episode. But yeah, when you get into the whole world of incenses and perfumes, and yeah, I mean perfumes, we could do a whole episode on that. There's a rich global history of perfume use. Like there are, of course, so many things to take into account personal taste even today, but you get into historical taste as well, like what constituted a good masking body perfume in various cultures and distinct points in time, you know, based on available materials. Yeah, totally. Now getting back into the into questions of okay, different sensors. Already mentioned the the Mount Po Sensor. There's another type of sensor that this particular paper mentions, and I had to look up examples of it. A Golden Duck was apparently a popular sensor for incense during this time and you can still see examples of this today. It is exactly what it sounds like, a golden or golden looking duck um where you can take the top off of the Duck, put the incense in there, get the incense burning, put the top half of the duck back on and smoke will rise out of the duck's mouth. Yeah, that's interesting. It almost looks like, uh, I don't know, it symbolize. Says that the duck is making a sound or something. Yeah, but I think the most for me anyway, the most amazing example of of a sensor for incense is that of the incense clock, as it's often referred to in English, and I was reading a very good summary and article about these in J store daily by Amelia Soft titled Keeping Time With Incense clocks, citing a few different scholars work, but I think one in particular is Andrew B Lou and it goes the article goes into detail about these, the splendid artifacts that date back at least to the sixth century, when a poet by the name of of you, John Wu, wrote quote. By Burning Incense we know the o' clock of the night. With graduated candle we confirm the tally of the watch. That's an English translation, of course, but I like the this kind of a novel translation. I like by you talking about knowing the o' clock of the night. Uh Huh, but again referencing the idea that you could create a contraption for burning incense in such a way that it had a pretty dependable rate of consumption and by that you could tell time right right. So that Second Line mentions a candle, and this is, I think, a reference to candle as a combustion based timekeeping device. But then by burning incense. This is where it's really interesting, because this is not it's not it's not a case of just having, okay, a super long incense stick it will take all night to burn, or even a night long spiral of incense. These incense clocks, and you'll definitely have to look up an image of these. These were ornate metal boxes with lids and compartments that contain specialized parts for their use, such as a UH, they just the author here describes a little shovel, a little damper and also various stencils for the laying out of an incense labyrinth within the box. AH, so you're making the smoldering and snake around in a maze, that's right now winding path of incense, and you have the different stencils, not just because you want different shapes but because, of course the length of the night changes with the seasons, and so different seasons will require a different Stencil, because the idea here is again the incense clock burns all night, it burns throughout the span of darkness and and you know, marks the passage of time via the scent of incense. You know. This actually reminds me of a technique I have used in a when trying to cook something for a long time over low heat and a charcoal grill before uh, and the method is essentially the snake. You create a kind of winding snake of charcoal and then you you put a lit coal on one end, and so the idea is that it's not all gonna like, catch on fire too fast and make the grill too hot. Instead, it will slowly burn into the next coal along the way and keep a low temperature as it creeps around the snake. Oh Wow, I don't think I've heard of that technique before. What, what sorts of things would you be cooking over a fire like that? Oh, like, you know, barbecue, basically, if you're trying to do something, you know, for a long time without it getting too hot. Interesting. Okay, so these incense UH clocks, as as they're sometimes referred these would these would again burn all night and there were noted. There were noted use in Beijing's tall drum tower during the Qing Dynasty, h four through nineteen, eleven soft sites. Another author, a historian of scientific instruments by the name of Silvio Bedini, who indicates that one could lay out a path of of not just one type of incense in one of these clocks, but alternating varieties of incense, or you could have scented wood chips placed at different points along the path and this would change the scent or have punctuated moments of scent that would be part of the olfactory experience of being in the vicinity of one of these clocks, so that you could you could essentially know what the hour is, know where you are in the journey through night based on the scent of the air. That's really interesting. So you wouldn't have to go look at it and check. Instead, there would be a an ambient difference, just like there is in the daytime. You can roughly tell what time of day it is by, you know, the position of the Sun, what the sky feels like in the light and all that, but this would allow you to do the same thing at night, except through your sense of smell. You just kind of have a vibe that it's as roughly, you know, four to five am. It's. It's fascinating because we have, you know, we're such visual creatures. Were certainly more visual than uh, than than smell base, but uh, and especially today, like if you want to know what hour of the night it is when you wake up in the night, of course we reach for our various timekeeping devices and find out. But you know that there's this this, this other approach of simply sort of observing the world. And granted, a lot of that observation would be visual, but but this is tying into a far more, far less visual route, though of course you could, I guess, just look at the incense clock as well and see where you are in the journey. So if also references a dragon shaped fire clock, they also involved the use of incense and this is a different design. It would look like a dragon, it would be kind of long and it would have a like a trough of incense running through the center and as this burned down again, kind of kind of like the snaking coals that you described, you know it's gonna Start on one end and burn towards the other, almost like a fuse, but slow, like a slow fuse of incense. But along the way they're going to be these little threads with metal balls hanging, and so it will regular intervals burn through those those those little bits of thread and make a ball drop into a metal pan, producing a sound, and that will mark the passing of the hours. Okay, but I like all of this too because it also brings to mind this idea of like the night is. It's like it's something to keep vigil through. You know, you need this sort of sacred time keeping in place to get you from from dust to dawn. Yeah, so I found all that just super interesting. I was not familiar with with incense clocks and I don't think I'd really given much thought to combustion based time keeping as well, aside from just sort of the the obvious environmental factors, and I guess this was probably something as well. I mean you go back into into really ancient prehistoric practices. You had the camp fire burning and maybe you keep that burning all night. Maybe it's a situation where it's kept burning Um for much longer, but there is that reality of the campfire burning down as time passes after you've stopped feeding the fire and then by morning it's reduced to nothing, or very little at all. Speaking of which, it looks like our incense for this episode has burnt all the way through, so we're gonna have to call it here. But we'll be back on Thursday with another episode dealing with Incense, UH, some of the technology involved historically withincense and also other practices of pertaining to incense. So be sure to check out part two. I think it'll be a fun ride. Those are our core episodes, Tuesdays and Thursdays. On Monday's we do listener mail, on Wednesday we do a short form artifact or monster fact, and on Fridays we do weird how cinema. That's our time to set aside most serious concerns and just talk about a strange film. Huge thanks, as always, to our excellent audio producer, Seth Nicholas Johnson.
