In the upper central arch there are again two levels. Below, David with his harp is clearly visible.

There is a monk beside him who could be Dom Bougler. Behind them there is a casket of sorts, and two angels can be seen lifting up its lid. Though one might think that this is the tomb of Our Lady, in fact it represents the Arc of the Allianc (Foederis Arca). Above, Christ raises his mother above the golden Propitiatory where God manifested himself in the Old Testament. It too is carried by two cherubim. All of this makes this representation of the Assomption highly original: instead of bringing Mary to her throne in heaven (as is seen in traditional scenes), here Christ raises her up to the very glory of God.
