This painting is one of the pinnacle panels of the now dismembered altarpiece painted by Ugolino di Nerio for the Franciscan church of Santa Croce, Florence. According to a nineteenth-century drawing attributed to Humbert de Superville, it was placed above the paired Sts James the Greater and Philip (Staatliche Museen, Berlin).

The prophet Isaiah is unfurling a sroll bearing the remains of an inscription from Isaiah 7:14.
