Here at O.11.029–036, Odysseus continues to follow the instructions of Circe as articulated earlier at O.10.521–537: 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.11.030–031, and a black ram for Teiresias in particular, O.11.032–033. And then, after having performed this prayer and these promises for all the dead, he sacrifices the two sheep that he and his companions have brought with them from the island of Circe: he cuts their throats, O.11.034–035, and then he lets their blood flow into the shallow bothros ‘pit’ that he has dug, O.11.036. Unlike O.10.526–527, where the sheep are said to be one black ram and one black ewe, those details are omitted here at O.11.034–035. Conversely, the detail at O.11.035–036 about the blood that flows into the bothros ‘pit’ from the cut throats of the sheep had been omitted at O.10.526–527. Likewise omitted at O.10.536–537—though it is implied—is the picturing of the dead in the act of actually drinking from the pit this blood that has flowed there from the cut throats of the sheep. Such drinking cannot happen, as Circe had instructed, until Teiresias arrives at the scene, O.10.536–537. And now that the blood has actually flowed into the pit, the instructions of Circe must be followed: no drinking of blood can be allowed until Teiresias arrives at the scene and drinks first, O.11.049–050. Teiresias finally gets to have his drink of blood only in O.11.095–098. Once he has his drink, Teiresias will make mental contact with Odysseus. See already the comment on O.10.490–495.
