LĪBRA

or AS, a pound, the unit of weight among the Romans and Italians. The uncial division, which has been noticed in speaking of the coin As, was also applied to the weight.—(See Tables at the end.) The divisions of the ounce are given under Uncia . Where the word pondo , or its abbreviations P. or POND. , occur with a simple number, the weight understood is the libra . The name libra was also given to a measure of horn, divided into twelve equal parts ( unciae ) by lines marked on it, and used for measuring oil.
