Liritzis, Ioannis
Ioannis Liritzis, is an archaeologist at the University of the Aegean who has proposed that the ancient Greeks journeyed across the Atlantics far as Canada. Liritzis presents his argument in a paper, co-authored with astronomer Panagiota Preka-Papadema, philosopher Konstantinos Kalachanis, meteorologist Chris G. Tzanis, and information technology consultant Panagiotis Antonopoulo(a).

Their claim is based primarily on the writing of Plutarch(b).
Although Liritzis does not link his theory with the story of Atlantis, he does express his views on Plato’s narrative in a later paper(c).
