καὶ τῇ ὧν λέγεις καὶ φθέγγῃ ἡρωικῇ ἀληθείᾳ ἀρκούμενος, εὐζωήσεις → and satisfied with heroic truth in every word and sound which you utter, you will live happy
Latin > English (Lewis & Short)
păcĭo: ōnis, f.,
I a contract, covenant (ante-class. for pactio): pacionem antiqui dicebant, quam nunc pactionem dicimus: unde et pacisci adhuc et paco in usu remanet, Fest. p. 250 Müll. (perh. too, ap. Fest. s. v. nuptias, p. 170, instead of ratio we should read pacio, acc. to the conject. of Dac. on the preced. passage).
