The third tells of Joseph and Jacob and is full of Egyptian local colour, a group of pyramids occurring twice.

On the wall are subsidiary scenes, such as Joseph before Pharaoh, the incident of Benjamin's sack with the cup in it, and the scene of the lean kine devouring the fat, which they are doing with tremendous spirit, all beginning simultaneously from behind.
The last dome relates the story of Moses, but it is by an inferior artist and does not compare with the others.

The miracle of the manna on the wall is, however, amusing, the manna being rather like melons and the quails as large as pheasants.

On the extreme left a cook is at work grilling some on a very open fire.

Another inferior mosaic on the north side of the atrium, represents S.Christopher with his little Passenger.
It is a pity that Titian's delightful version in the Doges' Palace could not have been followed.
The atrium is remarkable not only for its illustrations to Genesis.
