How does this artwork elucidate its Description?
The fresco portrays the last episode in Moses' life, in two sectors: a foreground one including two scenes, and a background one, with three further scenes and, on the right, a landscape. Moses is always recognizable through his yellow garments and the green cloak, as in the rest of the cycle. The artist made an extensive use of gold painting.
On the background Moses, on the Mount Nebo, receives by an angel the command baton, which gives him the authority to lead the Israelites towards the Promised Land. Below, Moses descends from the mountain with the baton in his hand, similarly to Cosimo Rosselli's Descent from Mount Sinai nearby. In the foreground, on the right, is a 120-year-old Moses  speaking at the crowd while holding the baton and a Holy Book: rays of light stem from his head. At his feet is the Ark of the Covenant, opened to show the Twelve Tables and the vase of the Manna. In the center, the procession includes a woman holding a child on her shoulders, wearing silk,  an elegant youth portrayed from behind and a naked man sitting. The latter two characters are attributed to Luca Signorelli, as well as the man with a stick next the throne of Moses.
On the left is the appointment of Joshua as Moses' successor; the former kneels to receive the command baton, while the prophet has  his cloak opened, showing a red-lined interior. Finally, on the left background, is the corpse of Moses on a shroud, surrounded by the dismayed Israelites.
