This manuscript is written in a clear and legible scribal hand. The textual and visual comparison shows that its sources were manuscripts that came out from the library of Cassiano dal Pozzo (1588-1657) in Rome: P1 was used for the text (ie T2286 which is present only in L2 and P1), while G1 was used for the illustrations and the added chapters. The illustrations are based on the drawings made by Nicolas Poussin and Pierfrancesco degli Alberti before 1638. They are carefully inserted in the body of the text. Like G1, L2 contains also the so called "added chapters" and their respective images, which Cassiano dal Pozzo had requested from Milan arond 1640. The added chapters were copied from Leonardo's Manuscrit A.
L2 belonged to the Marchesa da Soragna (née Melzi, died in 1860)
