The Roman amphora being equal to the cubic foot, and containing 80 librae of water, is one of the strongest cases of such relations, being often mentioned by ancient writers.
Pliny states the Egyptian talent at 80 librae = 396,000; evidently = the Abydus lion talent, which is divided by 100, and the mina is therefore 3960, or 50 x 79.2.
It also passed into Italy, but in a smaller multiple of 35 drachmae, or 1/4th of the Greek mina; 12 Italian weights (44) bearing value marks (which cannot therefore be differently attributed) show a libra of 2400 or 1/4th of 9600, which was divided in unciae and sextulae, and the full-sized mina is known as the 24 uncia mina, or talent of 120 librae of Vitruvius and Isidore (18) = 9900.
In literature it is constantly referred to; but we may notice the "general mina" (Cleopatra), in Egypt, 16 unciae=6600; the Ptolemaic talent, equal to the Attic in weight and divisions (Hero, Didymus); the Antiochian talent, equal to the Attic (Hero); the treaty of the Romans with Antiochus, naming talents of 80 librae, i.e.
