Maestro Leonardo of Florence.

[Footnote: So Leonardo writes his name on a sheet with sundry short
notes, evidently to try a pen. Compare the signature with those in
Nos. 1341, 1348 and 1374 (see also No. 1346, l. 33). The form
"Lionardo" does not occur in the autographs. The Portrait of the
Master in the Royal Library at Turin, which is reproduced--slightly
diminished--on Pl. I, has in the original two lines of writing
underneath; one in red chalk of two or three words is partly
effaced: _lionardo it... lm_ (or _lai_?); the second written in
pencil is as follows: _fatto da lui stesso assai vecchio_. In both
of these the writing is very like the Master's, but is certainly
only an imitation.]
