Reading a book that's set in fantasy Ireland/vikings. Sure you use that familiar setting as shorthand so you don't have to define the world.

"That's a caravel on the horizon"

What, what? *Frantic googling*

Vikings raided, traded with, and settled parts of Europe from the 8th to 11th centuries.
Caravels were ships used by the Spanish and Portuguese in the 15th and 16th centuries.

Thought so. Your history is bad.
