NEMESIUS, a Greek philosopher who embraced Christianity, and was made bishop of Emefa in Phœnicia, where he had his birth: he flourished in the beginning of the fifth century. We have a piece by him, intitled De natura hominis, in which he refutes the fatality of the Stoics and the errors of the Manichees, the Apollinarists, and the Eudomians; but he espouses the opinion of Origen concerning the pre-existence of souls (A). This treatise was translated by Valla, and printed in 1535. Another version was afterwards made of it by Ellebodus, and printed in 1665; it is also inserted in the Bibliotheca patrum, in Greek and Latin. Lastly, another edition was published at Oxford in 1671, folio, with a learned preface, wherein the editor endeavours to prove, from a passage in this book, that the circulation of the blood was known to Nemefius; which, however, was since shown to be a mistake by Dr Freind, in his History of Physic.
