in antiquity, a liquid measure among the Greeks and Romans. The Roman amphora contained forty-eight sextaries, and was equal to about seven gallons; one pint English wine-measure; and the Grecian or Attic amphora contained one third more. Amphora was also a dry measure, likewise in use among the Romans, and contained three bushels.

Amphora, among the Venetians, the largest measure used for liquids. It contains four bigorzas, the bigorza being four quarts, the quart four fachies, and each fachie four leras; but, by wholesale, the amphora is fourteen quarts, and the bigorza three quarts and a half.

Amphora, in astronomy, a name sometimes used for one of the twelve signs of the zodiac, more usually called aquarius. See Aquarius.
