The Carmina of Caius Valerius Catullus
We, maids and upright youths, are in Diana's care: upright youths and maids, we sing Diana.
Once thou didst profess to know but Catullus, Lesbia, nor wouldst hold Jove before me. I loved thee then, not only as a churl his mistress, but as a father loves his own sons and sons-inlaw. Now I do know thee: wherefore if more strongly I burn, thou art nevertheless to me far viler and of lighter thought. How may this be? thou askest. Because such wrongs drive a lover to greater passion, but to less wishes of welfare.
