Sæpe suo, cœlebs dixit Acerra, patri."
Joannis Audoeni, Epigr. 147. Lib. i. (nat. circa 1600.)
Again:
"Felix, quicunque dolore
Alterius disces posse carere tuo."
Tibul. lib. iii. 6. 43.
It is remarkable that the annotator on this passage in the Delphin ed., Paris, 1685, p. 327., quotes the line in question thus: "Consonat illud: Felix quem faciunt," &c., without giving the authority.
Again:
"Periculum ex aliis facere, tibi quod ex usu siet."—
Ter. Heaut. i. 2. 36. (Not 25., as in the Delphin Index.)
