Petrus de Ibernia, also known as Peter of Ireland, was a 13th-century writer and lecturer who is believed to have taught logic and natural philosophy to Thomas Aquinas.
[3] Peter lectured in natural philosophy at the University of Naples during Thomas Aquinas's term of attendance (1239–1244).
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.
Peter of Ireland studied Moses Maimonides with a Jewish–Christian group in the 1250s.
