Saint Jerome, Saint Mary Magdalene and Saint John the Baptist in the desert

In the centre, kneels Saint Jerome who, characterized by his peculiar attributes (a lion, a cardinal's hat and a book), beats his chest with a stone in front of the crucifix. On the right, among the rocks, an extremely emaciated Sain Mary Magdalene, clothed in her long hair, is engrossed in solitary prayer. On the left, Saint John the Baptist as a child.
