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