The mosaic, dated to the last quarter of 4th century BC (325-300 BC), adorns the floor of an antechamber leading to the tomb at the Kasta Hill burial complex in the ancient city of Amphipolis.
It covers an area of 4.5 by 3 meters and shows two male figures and a chariot pulled by two white horses.
The charioteer is a bearded man with a laurel wreath upon his head; running ahead of the chariot is the ancient Greek god Hermes in a hat and cloak.
The mosaic is made up of tiny pebbles that are white, black, gray, blue, red and yellow in color.
It isn’t completely intact – a circular part about 0.8 m in diameter near the center of the mosaic is missing.
The Greek archaeologists say that the tomb, together with the mosaic, is the work of Alexander the Great’s architect and technical adviser, Dinocrates of Rhodes.
They believe it contains the remains of a contemporary of Alexander, may be his general or relative – his mother, Olympias, or his wife, Roxana.
