Italian organist and composer. A licensed
butcher, he was however cathedral organist in Florence from
1432 until his death and visited Naples and Siena. He was
highly esteemed by his contemporaries, including Dufay, with
whom he corresponded, as well as Lorenzo il Magnifico. None of
his compositions, regarding which he was excessively
self-critical, survive, but he left after his death, and may
himself have copied, the important MS, beautifully ornamented,
containing no fewer than 352 works by the Italian masters of
the preceding 14th century, which today is considered the most
important and extensive source of music for this period and is
known as the Squarcialupi Codex.
