Fra Luca Bartolomeo de Pacioli (sometimes Paccioli or Paciolo; c. 1447–1517) was an Italian mathematician, Franciscan friar, collaborator with Leonardo da Vinci, and a seminal contributor to the field now known as accounting. He is referred to as "The Father of Accounting and Bookkeeping" and he was the first person to publish a work on the double-entry system of book-keeping.

Summa de arithmetica, geometria, proportioni et proportionalita (Summary of arithmetic, geometry, proportions and proportionality) is a book on mathematics written by Luca Pacioli and first published in 1494. It contains a comprehensive summary of Renaissance mathematics, including practical arithmetic, basic algebra, basic geometry and accounting, written in Italian for use as a textbook. The Summa is the first printed work on algebra in a vernacular language, and it contains the first published description of the double-entry bookkeeping system.
