QUADRANTAL, or AMPHŎRA QUADRANTAL, or AMPHŎRA only, was the principal
Roman measure of capacity for fluids. A standard model of the
_Amphora_ was kept with great care in the temple of Jupiter in the
Capitol, and was called _amphora Capitolina_. It contained 5·77
imperial gallons, or a little more than 5¾ gallons, or than 5 gallons
and 6 pints.
