Arzew (anc. Arsenarial), a seaport in Algeria, 26 miles from Oran. It exports a large quantity of grains, and has salt-works. Many Roman remains are found in the neighbourhood.

As, a weight of 12 ounces, the same as a pound or libra, in use in ancient Rome. It was divided into 12 ounces or unciae. The coin is said to have weighed 12 ounces in the time of Tullus Hostilius (q.v.), but it was eventually reduced to only half an ounce. It was stamped with the two-faced Janus on one side and with a ship's prow on the other.
