Mathematical Treasure: Luca Pacioli’s Euclid’s Elements

Cynthia J. Huffman (Pittsburg State University)

The Italian mathematician Luca Pacioli, who is known for publishing an influential compendium of 15th-century mathematics, titled Sūma de Arithmetica Geometria Proportioni & Proportionalita, and a book illustrated by Leonardo da Vinci, titled Divina Proportione, also published a Latin translation of Euclid’s Elements (Linda Hall Library call number QA31.E857 1509) in 1509. Below is the title page.

Title page for Pacioli's edition of Euclid's Elements.

Notice that the title mentions Euclid of Megara. During the European Middle Ages Euclid of Alexandria (ca 325 BC–ca 265 BC) was often confused with the Greek philosopher Euclid of Megara (ca 435 BC–ca 365 BC).

The name of Campanus is also mentioned on the title page (end of 4th line to start of 5th line). This edition of Euclid’s Elements is based on Johannes Campanus’ earlier (around 1260) Latin translation, with annotations added by Pacioli. There are sections in the work labeled “Verba Campani” or “The Words of Campanus,” as in the image below.

Detail from Pacioli's Euclid, referring to Campanus.

Like the translation by Campanus, which was the standard for over 200 years, Pacioli’s version of Euclid contains 15 books. The picture below shows the end of Book 14 (decimusquartus) and the start of Book 15 (decimusquintus).

The copy of the book at the Linda Hall Library was at one time in the library of a member of the well-known Florentine family Strozzi.Below is the page with the ownership written at the top and the family coat of arms at the bottom of the page, followed by a close-up of the coat of arms.
