The Greek alphabet as given above originated in Ionia, and was adopted at Athens in 403 B.C. The letters from A to T are derived from Phoenician and have Semitic names. The signs Υ to Ω were invented by the Greeks. From the Greek alphabet are derived the alphabets of most European countries. The ancients used only the large letters, called
a. Before 403 B.C. in the official Attic alphabet E stood for ε, η, spurious ει (6), O for ο, ω, spurious ου (6), H for the rough breathing, ΧΣ for Ξ, ΦΣ for Ψ. Λ was written for γ, and [lins ] for λ. Thus:
|ΕΔΟΧΣΕΝΤΕΙΒΟ[lins ]ΕΙΚΑΙΤΟΙΔΕΜΟΙ||ἔδοξεν τῇ βουλῇ καὶ τῷ δήμῳ.|
|ΕΓΙΤΕΔΕΙΟΝΕΝΑΙΑΓΟΤΟΑΡΛΥΡΙΟ||ἐπιτήδειον εἶναι ἀπὸ τοῦ ἀργυρίου.|
