Bishop of Emesa ([Homs], late 4th - early 5th century) in Syria. A learned prelate for whom little is known. He is probably identical with the provincial governor of Cappadocia (between 383 and 389) to whom  Gregory of Nazianzus sent three letters  (in 385) and a poem, inviting him to convert to Christianity. Flourished around 340-400, baptized by 390, he is known by his philosophical work entitled On the Nature of Man (De natura hominis). Written in all probability in the last decade of the 4th century, it could be characterized as the epitome of Christian anthropology. Based on the eclectic assimilation of the wisdom of Antiquity, Nemesius combined, in a synthetic way not clearly advanced before him, medicinal, philosophical and theological approaches on the nature of mankind following the syncretic spirit of his time. Familiar with pagan philosophy, having an excellent knowledge of medical science, Nemesius acquired his extensive education probably outside an ecclesiastical environment, as it is proved by the adoption of heterodox doctrines (e.g., the "Preexistence" of the Soul). His work was widely influential in both East and West. Maximus the Confessor (7th c.) was the first who namely mentioned him.
