Nicholas of Amiens

Nicholas of Amiens (Nicholaus Ambianensis) (1147 – c.1200) was a French theologian, a pupil of Gilbert de la Porrée.
He is known for a single major work, the "De arte catholicae fidei"; it is modelled after "Euclid's Elements". Some still attribute it to Alain of Lille, a question that has divided scholars since the nineteenth century.
