Epitome from Nagy 2015§92:
Menelaos, narrating for Telemachus and the assembled company the tale of his own homecoming from Troy, explains why the gods had temporarily checked the winds that could bring him back home in the final phase of his sea voyage, O.04.351–362. At one point in the tale, Menelaos is stranded on the island Pharos, offshore from Egypt O.04.354–360. And, in telling this part of the tale, the explanation that he gives for his temporary failure to sail on and to reach his homeland is this: because (352: ἐπεί) he had not performed a hecatomb. On the word hekatombē ‘hecatomb’, referring to a sacrificial slaughtering of one hundred cattle, see the comment on O.04.351–353.
