The notable geometers educated at this school included Jean-Charles della Faille, André Tacquet, and Theodorus Moretus.
His book, "Opticorum Libri Sex philosophis juxta ac mathematicis utiles," or "Six Books of Optics," is useful for philosophers and mathematicians.
It was published by Balthasar
I Moretus in Antwerp in 1613 and illustrated by the famous painter Peter Paul Rubens.
It included one of the first studies of binocular vision.
It also gave the names we now use to stereographic projection and orthographic projection, although the projections themselves were likely known to Hipparchus.
This book inspired the works of Desargues and Christiaan Huygens.
He died in Antwerp, aged 50.
