The Da Vinci Notebooks
I left Milan for Rome on the 24th day of September, 1513, with Giovanni [2] 793 , Francesco di Melzi [3] 794 795
441:793 : 1465. 2. Giovan; it is not likely that Leonardo should have called Giovan' Antonio Beltraffio at one time Giovanni, as in this note and another time Antonio, as in No. 1464 while in No. 1458 l. 16 we find Giovan'Antonio, and in No. 1436, l.6 Beltraffio. Possibly the Giovanni here spoken of is Leonardo's less known pupil Giovan Pietrino (see No. 1467, 5).
441:794 : 2. 3. Francesco de' Melzi is often mentioned, see Nos. 1350., Salai, Lorenzo and il Fanfoia.
441:795 ; 3. Salai. See No. 1519 note.
