Konstantinos Sismanidis concedes that he has "no proof but just strong indications" to back up his theory, presented today at a conference marking the 2,400th anniversary of the philosopher's birth.
Aristotle (384-322 BC) was a pupil of Plato and one of history's most influential thinkers.
Sismanidis said the structure unearthed in the ruins of Stageira, 70 kilometers east of Thessaloniki, was once a public monument where Aristotle was honoured after his death. No human remains were found there.
