The analysis of Thucydides 3.30.4 (from the speech of Teutiaplos), which contains the obscure phrase To usvov Toll roA mu ou, , as well as of all occurrences of the same phrase in Greek and Latin texts confirms the reading usvov against the vv.ll. . ll . uatvov and uotvov, , and helps establishing the meaning of the proverbial expression rota (Ta) usva Toll roA mu ou. .
