Ω, ὦ, τό,
twenty-fourth and last letter of the Ionic alphabet, ἀπὸ ἄλφα ἕως.ω. [[ “Corpus Glossariorum Latinorum” iii 283 (9th c.AD)] Refs 9th c.AD+]; thence used as a symbol of the end, the last, ἐγώ εἰμι τὸ ἄλφα καὶ τὸ ὦ (not τὸ ὦ μέγα) [[ NT.Rev.1.8, +others] NT]:—as a numeral ώ = 800, but ωνυμ = 800, 000. The epichoric _Attic dialect_ 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 usually = 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 (perispomenon accusative to [[ 2nd c.AD(?): Helladius Epigrammaticus cited in Phot. p.530B.), compare 5th c.BC: Achaeus Tragicus 33.3, 5th-6th c.BC: Plato Philosophus “Phaedrus” 244d, “Cra.” 420b, “Tht.” 203c ] Refs 5th c.BC+]: after the loss of the distinction between long and short vowels, ο and ω had the same pronunciation; they begin to be confused in Papyri of [[3rd c.BC ] Refs 3rd c.BC+](οἰκωνόμου [[ “PRev.Laws” 50.22 (3rd c.BC))] Refs 3rd c.BC+], but the name ω μέγα appears first in later Greek, [[ 9th c.AD: Theognostus Grammaticus “Can.” 13; κατὰ σχῆμα διπλοῦ ω ¯ ἤτοι μεγάλου 12th c.AD: Eustathius Episcopus Thessalonicensis 869.26; οἱ δὲ περὶ Ἀρίσταρχον αὐτὸ τὸ ποτήριον ω ¯ μέγα εἶναί φασιν, ὁποῖν ἴσως τὸ κατὰ δύο ῡ ἐσχηματισμένον [prev. author] 869.29 ] Refs 9th c.AD+]; ἐν τῷ ω ¯ μεγάλῳ under omega (in a lexicon), [[ [prev. author] 1828.49: διὰ τοῠ ω ¯ μεγάλου 2nd c.AD: Herodianus Grammaticus “Epim.” 208. ] Refs 2nd c.AD+]
