[Agorastocles] Ita me di ament, tardo amico nihil est quicquam inaequius, praesertim homini amanti, qui quidquid agit properat omnia. Sicut ego hos duco advocatos, homines spissigradissimos,May gods so love me, nothing is more unfair than having a slothful friend, even more so for a man in love, who in doing anything must all expedite. So I lead them, having called them forth, the most slow-paced men of them all, slower than freight ships [corbitae] upon a quiet sea.c. 194 BCE, Plautus, Poenulus 3.1.1–4
