The first known compendium of theological anthropology with a Christian orientation, De natura hominis presents a physiological and psychological study of man, based on Galenic and Platonic ideas and Christian doctrine; theorising that the spiritual life of man is conditioned by the body's natural limitations. It was one of the first works to propose that mental processes were localised in the cells in the cells of the brain. Nemesius (fl. fourth-century) appears to have been a physician before turning to life in the church, becoming Bishop of Emesa in present-day Syria. His comments on the heartbeat and pulse have been commonly erroneously interpreted as anticipation of Harvey's theory of the circulation. The editio princeps of the Greek text appeared in 1565.
