Disposal of the dead: Bones II

Happy Dia de Muertos (a day late)! 



Today we will briefly explore a few of the ways in which humans deal with the physical remains of their dead. In Western cultures, we predominantly bury our dead in cemeteries. In fact, this is so ubiquitous that I have met people who did not know that there were other well-accepted means of disposing of the dead beyond cremation!

There are a huge variety of ways in which people deal with their dead, and a variety of reasons, from practical to esoteric, why these practices arise. Please remember before passing judgement on any other cultures' treatment of the dead that these are frequently deeply personal, and deeply culturally ingrained traditions that may seem strange, but it is quite possible that what you would do seems just as strange to other people! For example, embalming and huge lacquered coffins (you know, like the normal kind) which keep the elements from decomposing a body kind of weird me out! Some of the ways people deal with their dead listed below are probably familiar to you. Others are likely not.
This post is meant to be a quick introduction, and by no means a comprehensive treatment of any of them. If you think of ways I have not listed, or would like to have a conversation (I would love to talk to you), please post below!

To start with, there are a number of considerations to be made when dealing with a corpse of any variety. Disease and decay are two of the big ones. It's not safe to leave a body lying around for very long, and the phobias that people develop around the dead are largely for this reason. It's natural to be afraid of handling something that can potentially kill you, even if maybe the form your phobia takes is a little more literal than it needs to be ;). So most practices around disposal of the dead are strongly tied to rituals around purity and cleanliness that would have started as (if they are not still) very literal concerns about sanitation.

There are four (very general) classifications of "burial", based on the way in which the body is disposed of. Sometimes two or more types are used in combination.

  • Earth burial
  • Air burial
  • Water burial
  • Fire "burial"

Within (or between) these overall categories of burial, there are a whole lot of variations in the exact methods by which people deal with their dead. Here are a few:



  • Traditional Western burial: in a coffin, in a cemetery (much of Europe and North America, and lots of other folks now. At the moment this is the most common form of burial)
  • Plain 'ol "stick a body in the ground" burial. Usually with a shroud, or limited grave goods. (the simplest, and traditionally most common form of burial)
  • Sky burial: Most forms of sky burial involve being laid out on a very high platform, and being consumed by birds. Sometimes the birds take everything, and sometimes the remaining bones are then buried or cremated (some Native American, some Buddhists, a few other folks)
  • Cremation: There are a whole lot of ways to cremate people. The traditional simple way to cremate people involves laying the body out on a wood platform, and setting it on fire. Then frequently the ashes are scattered to the wind (which could also be considered a form of sky burial)
  • Burial in barrows or mounds: instead of burying a body under the ground, a mound or small "hill' is built and the body is buried inside that. This kind of burial usually involves a lot of grave goods, as usually only very important people are buried in this fashion. A subset of this type of burial involves cairns, in which people are laid out inside a hollow barrow until they decompose, and then the bones are buried in the ground or totemized later. (ancient European, Native American mound builders, many others)
  • Burial in a pot: This is a thing. Like in a giant pot (Southeast Asia)
  • Partial to complete consumption of the dead: ritual cannibalism, to consume an enemy's power, or to consume the spirit of a loved one 
  • Burial in towers or pyramids or other giant structures: We really love building massive structures for our dead. Like a lot.
  • Mummification (mechanical or "natural"): Sometimes a body is buried in the sand and allowed to desiccate naturally. Several cultures have also used a variety of preservatives and organ removal to ensure this process works.
  • Bog burial: Bodies disposed of in bogs leather-ize naturally. It's pretty impressive.
  • Floating a corpse down the Ganges or another large river
  • Burial at sea
  • Viking ship burial (which is frequently 2 of the 3: earth, water, fire)
  • De-fleshing, accompanied by burial or totemization/display of bones: Flesh is actively removed, and the bones are displayed
  • Burial under the floor in your home (Catalhoyuk) 
  • Deposit remains in a cave. Frequently the same cave is used repeatedly.

  • Burial in spaaaaaace! this is totally a thing now. You too can be buried in space!

Happy Dark Sky Week


In case you haven’t heard by now, this week is National Dark Sky Week. Celebrated every April around the time of the new moon, this is a week when people all over the world turn out the lights at night to try to reduce light pollution.

What exactly is light pollution? This is the excess, unnatural light caused by human society that makes the night sky brighter than it should be. Light pollution is annoying for astronomers or anyone else trying to enjoy the awe-inspiring beauty of the stars and nearby planets at night through a telescope.  But beyond that, it also wastes energy, disrupts sleeping patterns, negatively affects nocturnal wildlife, and even disrupts the growth pattern of some plants and trees. So for the rest of the week, do your best to turn down the lights at night, and turn off what you’re not using. Spread the word! And while you’re at it, go outside and appreciate the amazingness that is the Night Sky. For more information, check out this page on Wikipedia:

In honor of Dark Sky Week, let me share with you an astronomical coincidence. Did you know that the Sun and the Moon are almost exactly the same size? … Well, actually they aren’t. But at some point in life you’ve probably noticed that they appear to be the same size, at least when viewed from the surface of the earth. This fact is most apparent during a total solar eclipse, when the Sun, Moon and Earth align in such a way that the sun is almost perfectly blocked out by the profile of the Moon.

It turns out that this is actually one of the more interesting coincidences in astronomy (at least as far as earthlings are concerned). As we all know, the Sun is the largest body in our solar system, and is much, much larger than the Moon. How much larger? Well, the diameter of the Moon is about 3,475 kilometers (or about 2,160 miles, for those of you still using the imperial system). For comparison, the diameter of the Sun is a whopping 1.39 million kilometers (or about 865,000 miles). That means the Sun is almost exactly 400 times wider than the Moon. So why do they look the same size, you ask? Well, it’s simple geometry! The Moon is about 370,000 kilometers (~230,000 miles) away from the Earth, while on average the Sun is about 150 million kilometers (~93 million miles) away from the Earth. This means that the Sun also happens to be roughly 400 times farther away from the Earth than the Moon is.

The end result? When viewed from Earth, the Sun and Moon appear to be the same size. If not for this happy coincidence, we would not be able to enjoy the magic of a solar eclipse, which every so often gives us a dark sky in the middle of the day.
