Petrarch, Familiar Letters
22.2.12-13 (tr. Aldo S. Bernardo):
I have read Virgil, Flaccus, Severinus, Tullius not once but countless times, nor was my reading rushed but leisurely, pondering them as I went with all the powers of my intellect; I ate in the morning what I would digest in the evening, I swallowed as a boy what I would ruminate upon as an older man. I have thoroughly absorbed these writings, implanting them not only in my memory but in my marrow, and they have so become one with my mind that were I never to read them for the remainder of my life, they would cling to me, having taken root in the innermost recesses of my mind.
legi apud Virgilium apud Flaccum apud Severinum apud Tullium; nec semel legi sed milies, nec cucurri sed incubui, et totis ingenii nisibus immoratus sum; mane comedi quod sero digererem, hausi puer quod senior ruminarem. hec se michi tam familiariter ingessere et non modo memorie sed medullis affixa sunt unumque cum ingenio facta sunt meo, ut etsi per omnem vitam amplius non legantur, ipsa quidem hereant, actis in intima animi parte radicibus.
