A Roman liquid measure containing six sextarii (Carm. de Pond.
72), or the
eighth part of the amphora. It was equal to the χοῦς
Greeks, about 5.76 pints.
There is a congius in existence, known as the Farnese congius, but now at Dresden, bearing
an inscription which states that it was made in the year A.D. 75, according to the
standard measure in the Capitol, and that it contained, by weight, ten pounds. This congius is
one of the means by which the attempt has been made to fix the weight of the Roman pound. See
Cato tells us that he was wont to give to each of his slaves a congius of wine at the
Saturnalia and the Compitalia. Pliny relates, among other examples of hard drinking, that
Novellius Torquatus of Mediolanum obtained a cognomen (tricongius
“a nine-bottle man”) by drinking three congii of wine at one sitting
