Circe’s instructions continue: in the course of offering his libation, in Hādēs, to the dead, Odysseus should also offer them a prayer, promising them that, if he succeeds in getting back home to Ithaca, he will then sacrifice there a barren cow for the dead in general, O.10.522–523, and a black ram for Teiresias in particular, O.10.524–525; then, having thus prayed, he should sacrifice to the dead a black ram and a black ewe together, O.10.526–527. It is understood that the blood of the black ram and the black ewe will flow into the bothros ‘pit’ mentioned at O.10.517—and that the dead will drink from there the blood of these sacrificial animals, O.10.536–537.
