Herodotos, The Histories 4.72ff
When a Scythian dies his nearest kin lay him upon a waggon and take him round to all his friends in succession: each receives them in turn and entertains them with a banquet, whereat the dead man is served with a portion of all that is set before the others; this is done for forty days, at the end of which time the burial takes place. After the burial, those engaged in it have to purify themselves, which they do in the following way. First they well soap and wash their heads; then, in order to cleanse their bodies, they act as follows: they make a booth by fixing in the ground three sticks inclined towards one another, and stretching around them woollen felts, which they arrange so as to fit as close as possible: inside the booth a dish is placed upon the ground, into which they put a number of red-hot stones, and then add some hemp-seed. Hemp grows in Scythia: it is very like flax; only that it is a much coarser and taller plant: some grows wild about the country, some is produced by cultivation: the Thracians make garments of it which closely resemble linen; so much so, indeed, that if a person has never seen hemp he is sure to think they are linen, and if he has, unless he is very experienced in such matters, he will not know of which material they are. The Scythians, as I said, take some of this hemp-seed, and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy, and this vapour serves them instead of a water-bath; for they never by any chance wash their bodies with water. Their women make a mixture of cypress, cedar, and frankincense wood, which they pound into a paste upon a rough piece of stone, adding a little water to it. With this substance, which is of a thick consistency, they plaster their faces all over, and indeed their whole bodies. A sweet odour is thereby imparted to them, and when they take off the plaster on the day following, their skin is clean and glossy.
