[193] ἕως scanned as a trochee represents of course an original “ἧος” (“εἷος” acc. to the rule of our MSS.), clearly by an error in transcription of an old Attic (“Η”)“ΕΟΣ”. This is the only scansion of the word in Il. except in 17.727; the alternative form “εἵως” is equally “ἧος” (but “τέως” is u- in 19.189, 24.658). In Od. the scansions u- or - (synizesis) are commoner. See van L. Ench. pp. 550 f.
