Nemesius’ De natura hominis, a physiological and psychological study of man, was highly esteemed during the Middle Ages. Nemesius, who wrote in the 4th century CE, was one of the first to propose that mental processes were localized in the cells or ventricles of the brain; his comments on the heartbeat and pulse have been erroneously interpreted as an anticipation of Harvey’s theory of the circulation. English translation, London, 1636. New English translation: Nemesius on the nature of man. Translated with an introduction and notes by R. W. Sharples and P. J. van der Eijk (Liverpool: Liverpool University Press, 2008).
