Saints Jerome, Michael, John the Baptist and Luke Standing in a Landscape with Attributes

A pen and ink drawing showing four saints standing side by side in a landscape. Each one of them is represented by his attribute, all on their saints' feet. On the far left is Saint Jerome in a cardinal attire, reading a book, with a lion sitting by his feet. Next to him is St. Michael, also known as St. Michael the Archangel. He is a winged figure, holding a long cross in both hands aimed at a dragon at his feet. Third from left is Saint John, wearing a camel skin robe cut to his thighs, holding a cross, and a lamb standing by his side. On the far right, Saint Luke is standing, holding an open book, with a winged ox by his side.
