Others regard the "ante-ilha" etymology as unsatisfactory, on the basis that "ante", in geographical usage, suggests it sits opposite another island, not a continent. As a result, alternative etymological theories of Antillia abound. One theory was that "Antillia" is merely a poorly-transcribed reference to Plato's "Atlantis

Each congregation founded a city, namely, Aira, Anhuib, Ansalli, Ansesseli, Ansodi, Ansolli and Con, and once established, burnt their caravel ships as a symbol of their autonomy. The reporting of this settlement comes courtesy of a young couple who eloped back to Europe on a rare trading ship and reported the seven cities as a model of agricultural, economic and cultural harmony. Centuries later, the island became known as a proto-utopian commonwealth, free from the disorders of less favoured states.

 proposed a solution to the riddle of Antillia in his bestseller 1421: The Year China Discovered America. Menzies analyzed the representations of Antilla on the various pre-Columbian maps, paying special attention to the conflicting names for the "seven cities" on the various maps. In Menzies' words, after decoding of the names of the "seven cities":
Menzies goes on to claim that "these names and maps are unequivocal proof that the islands were continuously settled by the Portuguese from before 1447 until 1492, the time of Columbus's first voyage." Menzies proposes an explanation for why the old maps locate Antillia in the Atlantic Ocean rather than the Caribbean Sea, arguing that the combination of the Portuguese dead-reckoning navigation technique and the Atlantic ocean currents caused navigators to mis-calculate Antillia's location on their maps. Menzies' claims and arguments about Antillia have not been recognized by professional historians.
