On one side of this ancient coin is the head of Zeus, king of the gods. On the other is a chariot drawn by galloping horses. Who might have held this coin when the Classical world was in full flower? A merchant who travelled to all the great ports of the Mediterranean? An actor who appeared in Greek dramas at the theater of Syracuse? An artist who painted frecoes in the villas of nobles and kings? There is a mystery and romance about such objects. They act as tickets to take the imagination on wondrous journeys into the vanished past.
