Gauging the volume of storage jars, particularly drug
jars, probably served to facilitate the sale or proper dis
tribution of the jars' contents. The jars whose dimen
sions are published fall into general groups according to
size: roughly one quarter of the jars measure between 17
and 18.5 cm high, slightly more than half of the jars mea
sure between 21 and 25 cm high, and three measure be
tween 27.5 and 33.5 cm high. Rather than simple height
measurements, however, it is the relative volume or ca
pacity of jars that appears to be most significant. One
scholar has shown that the volume of jars belonging to a
verifiable set relate to one another proportionally. In ad
dition, it seems that these measurements of capacity
