Brit.

/ɪˈəʊlᵻpʌɪl/,

/eɪˈəʊlᵻpʌɪl/, U.S.

/iˈoʊlᵻpaɪl/,

/eɪˈoʊlᵻpaɪl/

Forms:

α. 1600s– aeolipile, 1600s– aeolipyle, 1600s– eolipile, 1700s– eolipyle.

β. 1600s– aeolopile, 1900s– eolopile.

Origin: A borrowing from French. Etymons: French éolipile, eolipyle, aeolipyle.

Etymology: < French éolipile (1549 in Middle French), eolipyle (1682), †aeolipyle (1546 in Middle French) < classical Latin Aeolī pilae pneumatic mechanism or toy, literally ‘doorway of Aeolus’ (Vitruvius 1. 6) < Aeolī , genitive of Aeolus (see Aeolian adj.) + pilae ( < ancient Greek πύλαι , plural of πύλη gate: see -pyle comb. form), so called on account of the fact that the vapour bursts from the opening like the winds from the opened door of the cave of Aeolus. With the β. forms compare -o- connective, and also Middle French (rare) aeolopile (1552) and (with later use) German Aeolopile (1813 or earlier).

Now chiefly historical.

An experimental or educational device comprising a container which can be filled with steam or other heated vapour which escapes through one or more narrow apertures with sufficient force to cause the container to rotate.Often considered the first steam engine, the aeolipile is said to have been invented by Hero of Alexandria. In his version of the instrument, the water is heated in a cauldron which forms the stand for the ball-shaped vessel.
