The epichoric Att. and other alphabets of the Inscrr. had used o in differently to represent the sounds of the later ο and ω : Ω is a differentiated form of ο, and, though usu. = ω, was used in the Ionic islands of Paros, Thasos, and Siphnos with the value ο, while O or O represented the sound ω. The name of the letter was τὸ ὦ (perispom. acc. to Hellad. ap. Phot. p.530B. ), cf. Achae. 33.3 , Pl. Phdr. 244d , Cra. 420b , Tht. 203c : after the loss of the distinction betw. long and short vowels, ο and ω had the same pronunciation; they begin to be confused in Papyri of iii B. C.( οἰκωνόμου PRev.Laws 50.22 (iii B. C.)), but the name ω μέγα appears first in later Greek, Theognost.
