[1] In place of the more common e)to/s, the headword phrase, and the quotation of Aristophanes that follows, substitute the rare variant e)tw=s. The fact that this variant makes the quoted Aristophanes passage unmetrical suggests that this is a late-Greek homophonic variant based on the epic adjective e)tw/sios ['vain']. Same material (but with e)to/s) in Photius, Lexicon omicron650 Theodoridis, and similarly in a scholion on Plato, Republic 8.568A, where ou)k e)to/s occurs (web address 1). See also omicron 889.
[2] Aristophanes, Plutus [Wealth] 1166-1167, with minor variants (including the spelling of the headword) from the most accepted readings (see web address 2); the commentary comes from the scholia on this passage. Aristophanes' phrase translated here as 'on many rosters' is in the Greek 'under many letters'; for the system of jury empanelment in this era, involving letters of the alphabet, see D.M. MacDowell, The Law in Classical Athens (1978) 37-38.
