On the balustrade of this section sits an old man presenting a Greek book of mathematics. Next to him stands a younger scholar holding in his hands a sunring, a simple type of sundial with the time scale marked on the inside of the ring, identifying this scholar as a representive of gnomonics (the science of sundials).

The mechanical arts and mining are presented on the balustrade above the large arch to the Peace Wing. Three men use measuring instruments to investigate the nature of water.

On view are the signs for Mercury (quicksilver) and Mars (iron).
