Leonardo mentions the Pazzi family several times. In a memorandum in the Codex Arundel he writes: «Go to the Pazzi house [...]» and in Madrid Ms. II: «Cornazano de re militari, Guglielmo de’ Pazi has it». Evidently he frequented their home, situated in the piazza that still today bears their name, and was called "courtyard" for the vast garden that stretched from Borgo degli Albizi to Via dell’Oriuolo.
Of course Leonardo followed the vicissitudes of the conspiracy against the Medici in 1478, as shown by the famous drawing of the "Hanged man" in Bayonne, and studied Brunelleschi's architecture in the Pazzi Chapel in Santa Croce.
