Archaeologists working to uncover a large tomb in Amphipolis, Greece have discovered a large floor mosaic within the tomb. This mosaic is important, because many experts think it covers a grave that holds a member of Macedonian royalty. This find is very exciting, and comes a mere two days after bones found in Greece were confirmed to be those of Alexander the Great’s father.

According to The Guardian, the mosaic measures three by four and half meters wide, and covers the entire floor of the antechamber. The picture itself is made up of an assortment of colored pebbles, and depicts an image of horseman driving a two horse chariot after Hermes. Hermes was the Greek god of travel and also served as the guide to the underworld. These signs, along with the mosaic’s location, serve to provide evidence that the picture covers a grave of some sort.

There is much speculation on who rests in the tomb, but many agree that it is most likely someone who had relation to Alexander the Great. Some think it is one of his contemporaries, while there is also speculation that it could also be the burial site of one of his relatives. Possibly his mother, Olympias or even his wife, Roxana. However, as of right now who the grave belongs to is unknown.

The mosaic has been dated back to the last quarter of the fourth century BC (somewhere between 325 and 300 BC) which would place it during Alexander’s time. This is the reason for the speculation that the grave contains one of his contemporaries. This is an important find for archaeologists, and serves as another key piece to uncovering the past. As for Alexander himself, while many experts believe that he was buried somewhere in Egypt, no evidence of his tomb has yet to been found.
