Martial (Epigram iii. 56, 57) plays on the trick of the knave who had sold him wine instead of water; but he seriously declares that a cistern at Ravenna is more valuable than a vineyard. Sidonius complains that the town is destitute of fountains and aqueducts, and ranks the want of fresh water among the local evils, such as the croaking of frogs, the stinging of gnats, etc.
