were a sort of cups or vases made use of by the ancients for drinking out of, and other other purposes. Authors are not agreed as to the substance of which they were made. Some say it was a stone; some assert that it was a fluid condensed by being buried underground. All that we know concerning it is, that it was known by the name of murrha, and that Heliogabalus's chamber pot was made of it. The word is sometimes written myrrha.
