The right hand altar is dedicated to Our Lady. The title under which she is venerated here is Santa Maria del Buon Rimedio, which is a special devotion of the Trinitarians. The modern altarpiece (1926) by Felice Casorati shows The Madonna giving a slave's ransom to St John; the detailing is very well done, especially the vase of flowers featured. The saint is wearing the Order's distinctive white habit.
