Type of Spiritual Experience
J J O'Connor and E F Robertson – University of St Andrew, Biography
Dürer's final masterpiece was his Treatise on proportion which was at the proof stage at the time of his death.
Descriptive geometry originated with Dürer in this work although it was only put on a sound mathematical basis in later work of Monge. One of the methods of overcoming the problems of projection, and describing the movement of bodies in space, is descriptive geometry. Dürer's remarkable achievement was through applying mathematics to art, he developed such fundamentally new and important ideas within mathematics itself.
A description of the experience
Welcher aber ... durch die Geometria sein Ding beweist und die gründliche Wahrheit anzeigt, dem soll alle Welt glauben. Denn da ist man gefangen.
Whoever ... proves his point and demonstrates the prime truth geometrically should be believed by all the world, for there we are captured
