1489.
When Cotton printed his Typographical Gazetteer, 2nd series, (Oxf. 1866) he believed that an Indulgence of 1489 (altered to 1499), in the Library of Trinity College, Dublin, was printed at Oxford. It is “a small broadside on vellum, consisting of 24 lines only, printed very closely and occupying a space of about nine inches by six.” The Indulgence is from Johannes de Gigliis alias de Liliis Apostolicus Subdiaconus, granted by Pope Innocent iii: and is dated 1499, there being no name of place or date of printing. There is no doubt that Cotton was mistaken in attributing this piece to the Oxford press.
