He is thought to be the sculptor of the famous Venus de Milo statue.
According to inscriptions at the ancient city of Thespiae near Mount Helicon in Greece, he was a winner in contests for composing and singing.
Alexandros is thought to have sculpted a statue of Alexander the Great that is also displayed at the Louvre.
The attribution is based on an inscription from a now-missing plinth that was a part of the statue but was removed and "lost" due to museum politics and national pride at the Louvre in the 1820s.
The inscription and the style of its lettering cast into doubt the claim that the statue was an original by the master sculptor Praxiteles from Attica.
