Sit cisterna mihi, quam vinea, malo Ravennae, cum possim multo vendere pluris aquam. Your tanks for me, Ravenna, not your vines; The waters I can sell, but not the wines. Meglio avere a Ravenna un pozzo, e non già una vigna, perché l’acqua la posso vendere a molto di più.

Martial, Epigrams, Book 3, LVI
