Pietro da Cortona
The main altar was designed by Giovanni Battista Contini in 1684, and is surmounted by a large canvas, "Ss. Ivo, Leone, Pantaleone, Luca, e Caterina d'Allessandria in gloria di angeli", started by Pietro da Cortona (1661), and completed by Giovanni Ventura Borghesi after Cortona's death.
