History of the Peloponnesian War

The same winter the Athenians, according to their ancient custom, solemnized a public funeral of the first slain in this war in this manner.

Having set up a tent, they put into it the bones of the dead three days before the funeral; and everyone bringeth whatsoever he thinks good to his own.

When the day comes of carrying them to their burial, certain cypress coffins are carried along in carts, for every tribe one, in which are the bones of the men of every tribe by themselves. There is likewise borne an empty hearse covered over for such as appear not nor were found amongst the rest when they were taken up.
