The (; originally spelled ; "Book of the Three Scriptures") is a 1274 epic poem by Bonvesin da la Riva () written in the Lombard language.

It is composed of quatrains with only one rhyme. With this poem Bonvesin takes a distinguished place among the precursors of Dante. The book is constructed with skill and symmetry, and deserves the attention of Dante scholars.
