Word History

Etymology

borrowed from French & Latin; French bolide, borrowed from Latin bolid-, bolis, borrowed from Greek bolid-, bolís "hunting javelin, bolt (of lightning), throw of dice," derivative of bol- (in bolḗ or bólos "throw, cast"), nominal derivative from the base of bállein "to throw" — more at devil entry 1

Note: The word "bolide" is owed ultimately to the Roman natural historian pliny the Elder. Pliny used Latin bolis, plural bolides, as one of several terms describing "prodigies in the heavens" (caelestia prodigia) in his Natural History (2.37). For meteors in general he employs the word facēs (literally, "torches"), which "are only seen when they are falling" ("non nisi cum decidunt visae"). While some facēs are only burning in their front part, the bolidēs burn continually and hence leave a longer track ("bolis vero perpetua ardens longiorem trahit limitem"). While Pliny's other terms for his heavenly prodigies are fairly straightforward (facēs "torches," lampades "torches, lamps," trabēs "beams"), the Greek loanword bolis has no other record of use in Latin. In Greek it is a sparsely attested word, and it is uncertain what sense Pliny had in mind.
