Pietro Antonio Crespi Castoldi (Busto Arsizio 7 February 1557 - 10 November 1615) was an Italian historian and Catholic priest.
He was born on 7 February 1557 in Busto Arsizio, and was ordained a priest in 1581 by Charles Borromeo.
[1] He remained priest at Morazzone until 1589, when he returned to Busto Arsizio, to curate the Basilica of Saint John the Baptist, after an epidemic hit much of the congregation.
[citation needed] In 1614 he wrote “De oppido Busti relationes”.
Written in Latin, it became one of his most important works, and was translated by Luigi Belotti into Italian from 1925 to 1927.
