Detegat Orbes, nec sit terris

Ultima Thule.”

2ndly, to the island of Atlantis, described by Plato, in the Timæus, as lying in the Atlantic, opposite the Pillars of Hercules, and exceeding in size the whole of Africa and Asia.

And 3rdly, to the imaginary island of St. Brandan, seen at intervals far out in the Atlantic by the inhabitants of the Canary Islands.
