But the fame my genius has won shall not perish with time: genius claims a glory that knows no death.

[At non ingenio quaestium nomen ab aevo
Excidet: ingenio stat sine morte decus.]

Propertius (50–16 BC) Roman elegiac poet [Sextus Propertius]

Elegies, Book 3, Elegy 2, l. 25ff (3.2.25–26) [tr. Goold (Loeb) (1990)]

Telling Cynthia his literary genius will provide a more lasting memorial to her beauty than mere material monuments.

Because of the (ironic) corruption of the manuscripts of Propertius and speculating from internal references, some 19th Century scholars (e.g., Lachmann) argued for a different division of the elegies into books, thus the translations noted which instead label this as Book 4, Elegy 2.
