Petrus de Ibernia, also known as Peter of Ireland, writer and lecturer, fl. 1224–1252

Career

Peter lectured in natural philosophy at the University of Naples during Thomas Aquinas's term of attendance (1239–1244). he was the author of 'Determinatio magistralis', "on the question that the bodily organs have been created in order that they might carry out their functions, of the functions, created for the benefit of the organs." Peter felt this question to be purely a metaphysical one, despite his vocation being natural philosophy.

In 1260 he presided over a dispute on physics held before Manfred of Sicily.
