MERNOMUS, John Henry, was born in 1590 at Helmsstadt, where he afterwards professed physic, and died at Lubeck in 1655, having been, for some time, first physician at that place. He was the author of several learned works on medical subjects, particularly, 1. Jugurandum Hippocratis, Greek and Latin, 1643, in 4to.; and, 2. De Usu Flagrorum in Re Medica, Leyden, 1639. In the literary world he is known by a work, entitled Mæcenas, sive de C. Cilnii Mæcenatis Vita, Moribus, et Rebus gestis, Leyden, 1653, in 4to.; in which he has quoted almost every passage in the ancient authors where any thing is said of or allusion is made to Mæcenas, but has employed neither method nor criticism, and hence cannot lay claim to any higher merit than that of a mere collector.
