I left Milan for Rome on the 24th day of September, 1513, with
Giovanni [Footnote 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).], Francesco di
Melzi [Footnote 2,3: _Francesco de' Melzi_ is often mentioned, see
Nos. 1350.], Salai [Footnote 3: _Salai_. See No. 1519 note.],
Lorenzo and il Fanfoia.

[Footnote 4: _Lorenzo_. See No. 1351, l. 10 (p. 408). Amoretti gives
the following note in _Mem. Stor. XXIII:_ 1505. _Martedi--sera a di
14 d'aprile. Venne Lorenzo a stare con mecho: disse essere d'eta
d'anni 17 .. a di 15 del detto aprile ebbi scudi 25 d'oro dal
chamerlingo di Santa Maria nuova._ This, he asserts is derived from
a MS. marked S, in quarto. This MS. seems to have vanished and left
no trace behind; Amoretti himself had not seen it, but copied from a
selection of extracts made by Oltrocchi before the Leonardo MSS.
were conveyed to Paris on the responsibility of the first French
Republic. Lorenzo, by this, must have been born in 1487. The
sculptor Lorenzetto was born in 1490. Amoretti has been led by the
above passage to make the following absurd observations:

_Cotesto Lorenzo, che poi gli fu sempre compagno, almeno sin che
stette in Italia, sarebb' egli Lorenzo Lotto bergamasco? Sappiamo
essere stato questo valente dipintore uno de'bravi scolari del
Vinci_ (?).

_Il Fafoia_, perhaps a nickname. Cesare da Sesto, Leonardo's pupil,
seems to have been in Rome in these years, as we learn from a
drawing by him in the Louvre.
