Ut bene respondet Naturae ars docta! dedisset Vincius, ut tribuit cetera - sic animam - Noluit ut similis magis haec foret: altera sic est: Possidet illius Maurus amans animam.
[Footnote: These three epigrams on the portrait of Lucrezia Crivelli, a picture by Leonardo which must have been lost at a very early date, seem to have been dedicated to Leonardo by the poet. Leonardo used the reverse of the sheet for notes on geometry.]
Hujus quam cernis nomen Lucretia, Divi Omnia cui larga contribuere manu. Rara huic forma data est; pinxit Leonardos, amavit Maurus, pictorum primus hic, ille ducum.
Naturam, ac superas hac laesit imagine Divas Pictor: tantum hominis posse manum haec doluit, Illae longa dari tam magnae tempera formae, Quae spatio fuerat deperitura brevi.
