Note 36 — Chapter II · ISLANDS OF THE BLEST TRANSLATION
W. B. (William Bernard) Hillis translation
ἠέρα ἑσσάμενοι 125 (cf. 223; Ξ 282) is a naive equivalent for “invisible” as Tzet. correctly explains. This is how it is to be understood regularly in Homer whenever there is mention of envelopment in a cloud and the like.
