This scene is a detail of the fresco cycle in the Room of the Ark. Billowing clouds of aromatic incense surround the Ark of the Covenant, which is being carried in a solemn procession into the city of Jerusalem. The high priest of the Temple leads the pageant with the tabernacle containing the sacred Tablets of the Law.
This isn’t really related to any current lessons, but since we just finished studying Moses and the Ark of the Covenant and the tablets of the Ten Commandments, I thought you’d be interested. (And I just found it, and I think it’s really cool!) Thanks to the Web Gallery of Art for sharing the fresco and the description.
