From a copy in the Boston Public Library (facsimile), Internet Archive (scan)
1560
An exquisite book is the folio Livre de Perspective de Jehan Cousin Senonois, Maistre Painctre à Paris, printed at Paris in 1560 by Jean Le Royer, originally an engraver, but appointed by Henri II Imprimeur du Roy ès Mathématiques. Its title-page with an elaborate and sumptuous printers’s mark is followed by a great decorative engraving, presenting the five Corps Réguliers de Géométrie in a magnificent encadrement. This folio is printed chiefly from a mellow roman font, with running-titles set in a large lower-case letter.
