gibbon (n.)
long-armed ape of the East Indies, 1770, from French gibbon (18c.), supposedly from a word in the French colonies of India but not found in any language there. Brought to Europe by Marquis Joseph-François Dupleix (1697-1763), French governor general in India 1742-54. The surname is Old French Giboin, from Frankish *Geba-win "gift-friend," or in some cases a diminutive of Gibb, itself a familiar form of Gilbert.

polytheism (n.)

"belief in more gods than one," 1610s, from French polythéisme (16c.), formed from Greek polytheia "polytheism," polytheos "of or belonging to many gods," from polys "many" (from PIE root *pele- (1) "to fill") + theos "god" (from PIE root *dhes-, forming words for religious concepts).

The various modes of worship, which prevailed in the Roman world, were all considered by the people, as equally true; by the philosopher, as equally false; and by the magistrate, as equally useful. And thus toleration produced not only mutual indulgence, but even religious concord. [Gibbon]
