Bonaventure (b. 1221 as John of Fidanza) was an Italian medieval scholastic theologian and philosopher, the eighth Minister General of the Order of Friars Minor. He was a Cardinal Bishop of Albano. He was canonized on 14 April 1482 by Pope Sixtus IV and declared a Doctor of the Church in the year 1588 by Pope Sixtus V. He is known as the "Seraphic Doctor" (Latin: "Doctor Seraphicus"). Many writings believed in the Middle Ages to be his are now collected under the name Pseudo-Bonaventura.
Nicholas Love's Mirror is the most important work of Middle English literature you've never heard of. It's a devotional text that summarizes and comments on the Gospels, based on a earlier Latin devotional ... so it's not exactly a direct translation of Scripture, but close enough that Love felt the need to get special permission from Archbishop Arundel, who had outlawed English Bible translation in the wake of John Wyclif's heresy trials (at least according to Love himself, whose account of Arundel's enthusiastic response is debated). Only the Wycliffite Bible itself, the Canterbury Tales, and another devotional called The Prick of Conscience have more extant copies in Middle English. Clearly this was an important work of literature in England in the early 15th century. And this edition is an incredible achievement. Michael Sargent collated all 64 extant manuscripts, located in libraries around the world, to produce this definitive text.
