Word Origin & History
mantle
O.E. mentel "loose, sleeveless cloak," from L. mantellum "cloak," perhaps from a Celtic source. Reinforced and altered 12c. by O.Fr. mantel (Fr. manteau), from the L. source. Allusive use for "symbol of literary authority or artistic pre-eminence" is from Elijah's mantle [2 Kings ii.13]. As a layer of the earth between the crust and core (though not originally distinguished from the core) it is attested from 1940. The verb meaning "to wrap as in a mantle" is attested from c.1450.
