Калифорния как владения халифа:

http://en.wikipedia.org/wiki/Calafia
...The name of Calafia was likely formed from the Arabic word khalifa (religious state leader) which is known as caliph in English and califa in Spanish. Similarly, the name of Calafia's monarchy, California, likely originated from the same root, fabricated by the author to remind the 16th-century Spanish reader of the reconquista, a centuries-long fight between Christians and Muslims which had recently concluded in Spain.
...Putnam also wrote that The Song of Roland held a passing mention of a place called Califerne, perhaps named thus because it was the caliph's domain, a place of infidel rebellion.<16>
