The mosaic in the rectangular part of the room depicts the Greek legend of Arion. Arion was a famous poet of Corinth in Greece. He decided to attend a musical competition in Sicily, which he won, but on return from Sicily the avaricious sailors plotted to kill Arion and steal the rich prices he carried homewards. Arion was given the choice of suicide, allowing a proper burial on land, or being thrown in the sea to perish. He asked for permission to sing a last song.
