See evidence text
“‘‘When you have reached this spot, as I now tell you, dig a trench a cubit or so in length, breadth, and depth, and pour into it as a drink-offering to all the dead, first, honey mixed with milk, then wine, and in the third place water—sprinkling white barley meal over the whole. Moreover you must offer many prayers to the poor feeble ghosts, and promise them that when you get back to Ithaca you will sacrifice a barren heifer to them, the best you have, and will load the pyre with good things. More particularly you must promise that Teiresias shall have a black sheep all to himself, the finest in all your flocks. ”
