The Prophet Isaiah is a fresco located in Basilica di Sant'Agostino, an early Renaissance church in Rome.

It is an Italian Renaissance painting, influenced by Michelangelo's work on the Sistine Chapel ceiling.

[2] Johann of Goritz (also Gorizius), from Luxembourg, commissioned Raphael to paint the prophet Isaiah in fresco on a pillar in the Basilica di Sant'Agostino.

[4] The altar included this fresco of Isaiah and a marble grouping of Virgin with St. Anne by Andrea Sansovino.

[5] At the dedication of the church, a steady stream of literary friends honored Corycius with verses that were later published in the 1524 book Coryciana by Blosius Palladius, later Bishop of Foligno.
