[1] He may be the Girolamo di Pacchia mentioned by Vasari in his chapter on il Sodoma.
He painted frescoes on the Birth of the Virgin and the Annunciation for the church of San Bernardino.
He is recorded as having been a designer for pageants, and was active in the Sienese resistance against Florence.
One of his most important works is a tempera on panel representing the Madonna and Child with Saints, was once housed in the Church of Santi Margherita e Matteo in Ortignano Raggiolo, in the province of Arezzo.
Pacchiarotti's role in the Sienese resistance inspired Pacchiarotto, and How He Worked in Distemper, the title poem of a collection of the same name by Robert Browning, published in 1876.
