The Ars Magna (The Great Art, 1545) is an important Latin-language book on algebra written by Gerolamo Cardano. It was first published in 1545 under the title Artis Magnae, Sive de Regulis Algebraicis Liber Unus (Book number one about The Great Art, or The Rules of Algebra). There was a second edition in Cardano's lifetime, published in 1570.
Cardano suggested drafting the text three times in order to smooth any irregularities that might indicate the hidden words. The recipient of the message must possess an identical grille. Copies of grilles are cut from an original template, but many different patterns could be made for one-to-one correspondence.
Gerolamo Cardano (Italian: [dʒeˈrɔːlamo karˈdaːno]; also Girolamo [1] or Geronimo; [2] French: Jérôme Cardan; Latin: Hieronymus Cardanus; 24 September 1501– 21 September 1576) was an Italian polymath whose interests and proficiencies ranged through those of mathematician, physician, biologist, physicist, chemist, astrologer, astronomer, philosopher, music theorist, writer, and ...
The mathematical methods of probability arose in the investigations first of Gerolamo Cardano in the 1560s (not published until 100 years later), and then in the correspondence Pierre de Fermat and Blaise Pascal (1654) on such questions as the fair division of the stake in an interrupted game of chance.

Cardano is not known to have proposed this variation, but he was a chess player who wrote a book on gaming, so the pattern would have been familiar to him. Whereas the ordinary Cardan grille has arbitrary perforations, if his method of cutting holes is applied to the white squares of a chess board a regular pattern results.
Metoposcopy was developed by the 16th century Italian polymath Gerolamo Cardano, considered to be one of the foremost mathematicians of the Renaissance. His seminal work Metoposcopia libris tredecim, et octingentis faciei humanae eiconibus complexa , illustrated with engravings of 800 foreheads, was written in 1558 and published posthumously in ...
