Luis de Granada was a prominent Spanish Dominican friar, theologian, and writer who lived from 1504 to 1588. Born in Granada to a poor family, he joined the Dominican Order at age nineteen and later studied at the prestigious Colegio de San Gregorio in Valladolid. He achieved great success as a preacher for forty years, eventually moving to Portugal where he served as the Prior Provincial. Throughout his life, he maintained an ascetic lifestyle, donating all proceeds from his extensive literary output to the poor.
