Leonardo da Vinci's Geometric Sketches - Cylinder and Cone

Frank J. Swetz (The Pennsylvania State University)


We thank the Pennsylvania State University Libraries for allowing Convergence to publish the images above of Da Vinci’s illustrations from their copy of the beautiful facsimile of Pacioli’s De divina proportione published by Silvana Editoriale, Milan, Italy, 1982. This facsimile is of the manuscript copy of Pacioli’s Divina held by the Biblioteca Ambrosiana in Milan, one of only three Pacioli made.

For images from the 1509 printed edition of De divina proportione, see:

  • A "mathematical treasure" in Convergence providing additional information about Pacioli’s Divina proportione, along with three images from the copy housed at the University of Oklahoma Library, and
  • Another "mathematical treasure" in Convergence providing two images from the copy of Pacioli’s Divina proportione housed at Columbia University’s Butler Library.
