Let us eat and drink, for tomorrow we die

When the rich give a party and the meal is finished, a man carries round among the guests a wooden image of a corpse in a coffin, carved and painted to look as much as the real thing as possible, and anything from eighteen inches to three foot long; he shows it to each guest in turn, and says: 'Look upon this body as you drink and enjoy yourself; for you will be just like it when you are dead.'

Herodotus - Histories (II, 78)
