In February 54 b.c. Cicero concludes a missive to his brother with a passing and – for us – tantalizing remark: Lucreti poemata ut scribis ita sunt, multis luminibus ingeni, multae tamen artis. sed cum veneris. virum te putabo si Sallusti Empedoclea legeris; hominem non putabo. Quintus had, it seems, read De rerum natura, or at least parts thereof, just before he left Rome for an undisclosed location nearby, and he shared his enthusiasm with his brother per codicillos. Meanwhile, he was corresponding with Julius Caesar, whose staff in Gaul he was about to join. When, a few months later, he was stationed with Caesar, he was involved in another literary affair, this time concerning his brother who wrote to him, inquiring about his autobiographical De temporibus suis:
quo modo nam, mi frater, de nostris versibus Caesar? nam primum librum se legisse scripsit ad me ante, et prima sic ut neget se ne Graeca quidem meliora legisse; reliqua ad quendam locum ῥᾳθυμότερα (hoc enim utitur verbo). dic mihi verum: num aut res eum aut χαρακτὴρ non delectat?(Q. fr. 2.15.5)
