Wild speculations -- that the body of Alexander the Great lies in the mound -- continue in Greek media and in modern-day Amfipoli and Mesolakkia, the two villages closest to the mysterious mound.
It's a claim, or hope, that archaeologists and historians strongly dismiss.
History has it that after Alexander died in Babylon, now in central Iraq, in 323 B.C., his body, en route to Macedon, was hijacked by Ptolemy and taken to Egypt. The sarcophagus of the warrior king was then moved from Memphis to Alexandria, the capital of his kingdom, and there it remained until Late Antiquity.
By the fourth century A.D., the tomb's location was no longer known.
In the heated guessing game on who is buried under the colossal mound, the most viable candidates are the members of the king's immediate family, including his wife, Roxana, his young son, also named Alexander, and of course Olympias.
Other theories include Androsthenes, Laomedon and Nearchus, Alexander's admirals, Hephaestion and Antigonus Monophthalmus, generals of Alexander's army, and even Cassander, who killed Alexander's wife Roxana and his son Alexander IV to succeed the Macedonian king.
According to Chugg, the fact that the colossal statues in the mound's underground space represent female guardians, would rule out a male occupant.
"Olympias remain the leading candidate," he said.
Olga Palagia, chair of the department of archaeology at Athens University, disagrees with Chugg's interpretation and with the tomb dating altogether.
"The style of the Caryatids is archaistic, inspired by the formal language of the sixth century B.C. This style was invented in Athens in the fifth century B.C. but was initially used for reliefs or smaller statues," Palagia told Discovery News.
According to Palagia, archaistic caryatids on a colossal scale first appear in the first century B.C. in Eleusis, a shrine 15 miles north-west of Athens.
"The colossal archaistic caryatids, the colossal sphinxes, the lavish use of marble, the long vaulted corridor indicate that the Amphipolis tomb cannot date before the first century B.C," Palagia said.
"It is therefore not a Macedonian tomb, because such tombs disappear in the mid-second century B.C. when Macedonia was conquered by the Romans," she concluded.
She noted Amphipolis was the headquarters of the Roman army of Octavian, later known as Augustus, and Mark Antony during the Roman civil war against Brutus and Cassius, Julius Caesar's assassins.
The final battle took place at Philippi, 32 miles from Amphipolis, in 42 B.C. Octavian and Mark Antony were victorious.
"This battle changed the course of history because it enabled Octavian to go on to create the Roman Empire," Palagia said.
"Considering the momentous importance of the battle of Philippi and the vast amounts of both gold and manpower at the disposal of Octavian and Mark Antony, it may well be argued that the tomb of Amphipolis housed the cremated remains of the Roman generals,"
At last, another hypothesis is shaping up among scholars: the Amphipolis mound may not be a tomb at all.
"We keep using the word 'tomb' for Amphipolis but one interesting feature is the lack of a door. It may have been removed when the structure was sealed, but the lack of a door so far suggests the lack of a burial," classical archaeologist Dorothy King wrote in her blog.
According to King, the round shape of the structure, the lack of a door and the sources which all say Alexander was buried in Egypt, all suggest the Amphipolis mound was more likely a tribute to the cult of Alexander the Great.
"This is just an idea I discuss ... things could change with new finds," King told Discovery News.
