Ancient Greek mosaics were initially made with rounded pebbles, and then with tesserae which gave more colour and a flat surface. They were popular in the Hellenistic period, at first as decoration for the floors of palaces, but eventually for private homes.

The figure on the right is Alexander the Great and the figure on the left wielding a double-edged axe is Hephaestion, one of Alexander’s loyal companions.
