Audience Chamber - below the astronomer mosaic is a mosaic showing seasonal farming scenes surrounding the protectress Medussa - spring Ceres teaching Triptolemus to plough; summer Achilles frightens a girl when it is revealed that he is a man; Autumn mad king Lycurgus with his double headed axe chases Ambrosia, the gods save her by turning her into an encircling vine; winter Attis as a well wrapped shepherd is receiving water for his sheep. The mosaic at the bottom of the picture depicts the sea, the merman has a steering oar and a bowl of oysters; the sea can be frightening but it can also be tamed, the oar and the tritons holding the shepherds crook and flute are to show that we are in control.
