This paper analyses the meaning of μύκλος in two passages of Lycophron’sAlexandra. The thorough study of the contexts shows that the most likely interpretation of the word in both verses is “donkey”: μύκλοις γυναικοκλῶψιν “woman-stealing donkeys” and τὸν ἐργάτην μύκλον “the hard-working donkey”. The definition “lewd” of ancient scholia, assumed by modern lexica and scholars, is nothing but anad hocexplanation of the former passage which does not suit the latter. After refuting previous etymologies, I contend that μύκλος is originally a (...) deverbative adjective in *‑lo‑built on the onomatopoetic aorist μῠκεῖν “bellow”. (shrink)
