There’s a passage in Seneca’s Medea that seems to have foretold the discovery of America 1400 years before the event:

Venient annis secula seris,
Quibus Oceanus vincula rerum.
Laxet, et ingens pateat tellus
Tethysque novos detegat orbes
Nec sit terris ultima Thule.

“The times will come in later years when ocean may relax the chain of things, and a vast continent may open; the sea may uncover new worlds, and Thule cease to be the last of lands.”
