(ξέστης/xéstēs). From the turn from the 3rd cent. BC to the 2nd onwards, the term xestes is recorded as a Greek term for the Roman sextarius, a fluid and dry measure of capacity (= c. 0.546 l) corresponding to 1/48 of an amphora , 1/6 of a congius or 2 heminae, 4 quartarii and 12 cyathi. In late Antiquity Egypt, 72 xestai/sextarii corresponded to an artábē, which was subdivided into 48 choínikes. Hence a choínix can be equated with 11/2 xestai/sextarii.
