Angiolo Agostino Mazzinghi was a 15th-century Italian Carmelite friar and priest from Florence. Born in 1385, he became a prominent figure within his order, serving as a teacher of theology in both Florence and Frascati. He was deeply committed to the Carmelite Rule and played a significant role in the reform of the Our Lady of the Wood observance. Known for his intense devotion to the Eucharist and the Virgin Mary, he spent his final years in quiet contemplation before passing away in his home city in 1438.
