NICOLAUS, surnamed Myrepsus, or "the ointment-maker," the author of a Greek pharmaceutical work, flourished in the thirteenth century at the court of the Emperor John III. His treatise is known to the public only in the form of a Latin translation entitled De Compositione Medicamentorum. Its value is almost cancelled by the fact that it places the most absurd monkish charms and talismans in the category of remedies, and is little else than a compilation from Nicolaus Præpositus, and other medical writers. Yet it has found a place in the second volume of H. Stephens's Medicae Artis Principes, fol., Paris, 1567, and has since been reprinted.
