Greek police arrested two men last week for trying to sell several artifacts, including a bronze sculpture of emperor Alexander the Great from the 4th century B.C., for which the asking price was 7 million euros.

Police identified the suspects as a 48-year-old Thessaloniki businessman and a 51-year-old farmer, but did not provide their names.

The men were arrested last week near the town of Kavala, east of Thessaloniki, police said.

Police searched their car and found a treasure trove that included a 65-centimetre (2-foot) statue of Alexander, two bronze heads of a boy and a young man and other artifacts, including two rare Qurans.

“According to our information, the (suspects) have been trying to sell the sculptures for about a year,” senior Thessaloniki police official Dimitris Tsaknakis said “They have been asking 7 million euros for the Alexander sculpture and between 4-6 million euros for the boy’s bronze head.”

Experts say the Alexander statue appeared to come from the workshop of Lysippos, Alexander’s personal sculptor.

Chemical tests are being conducted at the Thessaloniki Archaeological Museum to see whether the sculpture is an original or a contemporary copy, since Lysippos’ workshop, which employed several artists, also produced replicas of original works.

The young boy’s bronze head, apparently part of a larger sculpture, is dated from the Roman era, in the 1st century B.C.

Police officials say it is likely the two smuggled the antiquities and the Qurans from Turkey, but at this point they are not certain about their place of origin.
