Same entry in ps.-Zonaras. The headword adjective, here in the neuter singular, is not otherwise attested, and is possibly a mistake for megh/raton or megh/riton. The phrase megh/rita te/kna qea/wn "much contended-for children of goddesses" (Hesiod, Theogony 240) has the textual variant megh/rata te/kna qea/wn "most lovable children of goddesses" (LSJ s.v. megh/ritos, from e)rato/s); and megh/ratos is glossed in the Etymologicum Magnum and ps.-Zonaras with the same word, mega/lws e)pe/rasta. (Compare also, here, under alpha 467, alpha 2808, epsilon 2199, epsilon 2987, iota 353.)
The word also turns up in the Vision of Dorotheus (3-4 CE) 307, though apparently as an aorist imperative of megai/rw (cf. mu 396).
