Petrus de Ibernia, also known asPeter of Ireland, was a 13th-century writer and lecturer who is believed to have taught logic and natural philosophy toThomas Aquinas.^[1][2]

Peter of Ireland is mentioned by the Aquinas' biographers Wilhelm of Tocco and Peter Calo.^[3]

Peter lectured innatural philosophy at theUniversity of Naples duringThomas 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 ametaphysical one, despite his vocation being natural philosophy.

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

Peter of Ireland studiedMoses Maimonides with a Jewish–Christian group in the 1250s.^[1]
