[225] ἑῆος: in the reading of G ἑοῖο we have a reflex of the controversy among the Alex. critics whether ἑῆος or ἑοῖο was to be read in many passages in Hom., Aristarchus favouring ἑῆος, Zenodotus ἑοῖο. ἑῆος is the gen. of ἐΰς (with altered breathing). Apollon. Lex. explains ἑῆος by ἀγαθοῦ, προσηνοῦς. This is the only passage outside Hom. where ἑῆος occurs, and Buttmann says, "Ap. followed the old explanation, προσηνοῦς, which suits this case perfectly well, as Pelias wished Acastus not to leave him." For the Homeric usage v. Buttm. Lexil., Leaf on Il. 1. 393, Monro H. G. 255, La Roche Textkr. 233. As we find πατρὸς ἑοῖο five times in Ap. without any further trace of ἑῆος, Rzach and Brugmann regard ἑῆος in this passage as a gloss due to Aristarchus' recension of Hom., and ἑοῖο as the genuine reading. Merkel is inclined to the same view.
