Aguillon (or Aguelon), Francois D

Aguillon (Or Aguelon), Francois D', a Belgian Jesuit, was born at Brussels in 1567. He first introduced the study of mathematics among the brothers of the Low Countries, taught philosophy at Douay, and theology at Antwerp, where he was rector of the college. He died at Seville in 1617. He wrote, Opticorum Lib. VI Philosophicis juxta ac Mathematicis Utiles (Antw. 1613, fol.). This work contains the first mention of stereographic projection. This was known from the time of Hipparcus, but had never received a name. Aguillon worked on catoptrics and dioptrics until his death. See Hoefer, Nouv. Biog. Generale, s.v.
