In the middle there are palm trees. On the right there is a group of seven Muses, in the middle Clio (History) is sitting with her right hand raised, her left elbow reposed on a pile of books. At the bottom Melpomene (Tragedy) is reclining, she turns her bare back to the viewer, her head is turned and she seems to be contemplating the tragic mask which she holds in her left hand. At the top we see Urania (Astronomy) inspecting heaven with a telescope. It is to be noted that Asam took care to choose a representative set of Muses to fit the theme of his fresco.
