He noted that in the mosaic scene, Philip is depicted at about his age at death, which was forty-seven. He died in 336BC, twenty years before the death of Olympias in 316BC.
"All the human portraits in the mosaic therefore need to be consistent with the year 336BC in order for them to work as a group portrait of the members of the royal family," Chugg said.
Therefore, Olympias would have been in her mid thirties in 336 B.C. Rendering her more youthful could be seen as a compliment to the deceased.
"Hermes looks like a young, clean shaven man of about 20 and there is something curiously familiar about him to me," Chugg said.
The riddle has a simple solution, says the researcher.
"The male member of the royal family who was twenty when Philip died and who pre-deceased Olympias was their only son, Alexander the Great," Chugg said.
He noted there is a family resemblance between Hermes and Persephone. "It is not difficult to believe that they are mother and son," Chugg said.
At the press conference, Mendoni confirmed that the scene of the abduction of Persephone strengthens the theory that the occupant of the massive tomb is a member of the Macedonian royal family.
