Note 152
Ancient Greek is the expression of Olympiodorus, which he seems to have borrowed from Æolus, a tragedy of Euripides, of which some fragments only are now extant (Euripid. Barnes tom. ii. p. 443, ver. 38). This allusion may prove that the ancient tragic poets were still familiar to the Greeks of the fifth century.
