[Footnote: This passage was first published by AMORETTI in _Memorie
Storiche_ Cap. X: Una sua opera da riportarsi a quest' anno fu il
bagno fatto per la duchessa Beatrice nel parco o giardino del
Castello. Lionardo non solo ne disegno il piccolo edifizio a foggia
di padiglione, nel cod. segnato Q. 3, dandone anche separatamente la
pianta; ma sotto vi scrisse: Padiglione del giardino della duchessa;
e sotto la pianta: Fondamento del padiglione ch'e nel mezzo del
labirinto del duca di Milano; nessuna data e presso il padiglione,
disegnato nella pagina 12, ma poco sopra fra molti circoli
intrecciati vedesi = 10 Luglio 1492 = e nella pagina 2 presso ad
alcuni disegni di legumi qualcheduno ha letto Settembre 1482 in vece
di 1492, come dovea scriverevi, e probabilmente scrisse Lionardo.

The original text however hardly bears the interpretation put upon
it by AMORETTI. He is mistaken as to the mark on the MS. as well as
in his statements as to the date, for the MS. in question has no
date; the date he gives occurs, on the contrary, in another
note-book. Finally, it appears to me quite an open question whether
Leonardo was the architect who carried out the construction of the
dome-like Pavilion here shown in section, or of the ground plan of
the Pavilion drawn by the side of it. Must we, in fact, suppose that
"_il duca di Milano_" here mentioned was, as has been generally
assumed, Ludovico il Moro? He did not hold this title from the
Emperor before 1494; till that date he was only called _Governatore_
and Leonardo in speaking of him, mentions him generally as "_il
Moro_" even after 1494. On January 18, 1491, he married Beatrice
d'Este the daughter of Ercole I, Duke of Ferrara. She died on the
2nd January 1497, and for the reasons I have given it seems
improbable that it should be this princess who is here spoken of as
