First Accounting Handbook

Luca Pacioli, the mathematician who instructed Leonardo da Vinci and for a time lived in the same house, hand-wrote a remarkable textbook, the Tractatus mathematicus ad discipulos perusinos, for his students at the University of Perugia, where Pacioli taught from 1477 to 1480.

This celebrated source-book of merchant arithmetic, preserved as Vat.lat.3129 at the Vatican Library, is seen as the start of the formal study of accounting. A color scan has just been presented online, replacing a murky black and white image on the library portal. It is among the most celebrated items to emerge from the digitization program in the past week. Below is the full list of 107 items:
