Pepe Carvalho, the central character of the series of detective novels written by Manuel Vázquez Montalbán, has a next-door neighbour named Enric Fuster. Fuster is a fellow gastronome, a confidant, and an occasional advisor. He has the peculiarity that he rarely travels any further from Barcelona than to his home village. Carvalho poetically describes this quirk in a number of the books as being similar to the beliefs of the Chaldeans, as in this example:
Like the Chaldeans who thought that the world ended with the mountains that encircled them, Enric Fuster, along with everyone else from the Maestrazgo, thought that anything beyond his own horizon was intergalactic.
[Southern Seas, translated by Patrick Camiller (1986), bolding mine.]
Is there a classical authority that describes the Chaldeans as believing this?
