As stated by Frati and Segarizzi in regards to ms. Venice, BNM, It. II.2, the compendium is not the same as Taddeo Alderotti's (Frati and Segarizzi 1909: 192). This is - at least for the moment - the only extant witness for such work. The text is divided into 10 books (not 12, as it usually happens within the manuscript tradition of Taddeo's compendium).
