Piri Reis
According to historians Paul Hoye and Paul Lunde, while Hapgood's work garnered some enthusiasm and praise for its thoroughness, his revolutionary hypotheses largely met with skepticism and were ignored by most scholars. In the book "The Piri Reis Map of 1513" Gregory C. McIntosh examines Hapgood's claims for both maps and states that "they fall short of proving or even strongly suggesting that the Piri Reis map and the Fine map depict the actual outline of Antarctica."
