Table of possible combinations of numbers and letters from "The Great Art of Learning".

According to Kircher, mathematics (arithmetic equa­tions and geometry) form the foundations of the world if only because God created everything with mathe­matical precision. Using various tables and diagrams, the scientist tried to make mathematics more accessi­ble and understandable to a wide a range of people as possible. To that aim, he also created a system for mak­ing learning mathematics easier. He analysed the po­tential of various number combinations, created tables of symbol and number combinations and diagrams, and was one of the forefathers of text-deciphering mechanisms.
