MYREPSUS (Nicolas), was a physician of Alexandria, to whom we are under great obligations for the pains he took to collect, into a kind of pharmacopoeia, all the compound medicines which lie scattered in the works of the Greeks and Arabian writers. his work was accomplished before the beginning of the 14th century; and though written in barbarous Greek, continued for a long time to be the rule of pharmaceutical preparations in Europe. A translation of it into Latin by Leonard Fuchs is entitled Opus Medicamentorum, in Setticenis quadraginta octo digestum. There are a great many editions of this work: the best is that of Hartman Beverus, Nuremberg, 1638, 8vo.
