Analysis
This 17th-century manuscript was probably compiled in Milan as it is suggested to the letters “A.M.” written on its spine. The letters “A.M.” have traditionally been interpreted as the initials of Ambrogio Mazenta, the Milanese owner of numerous original manuscripts by Leonardo who visited Rome around 1640 and who was involved in Cassiano dal Pozzo’s editorial project on Leonardo’s Treatise on Painting (Barone 2011). The watermark on the added pages to the manuscript is similar to watermarks documented in Cassiano dal Pozzo’s library, suggesting that RC1 was compiled elsewhere but then made available to Cassiano in Rome (Barone 2011). The textual and visual comparison suggests that RC1 is similar to R1 and VB, two other 17th century copy emanating from Cassiano’s library.
