Eolopiles were primitive steam engines invented by Heron of Alexandria.

DescriptionEdit

Described as "a parlour trick" by Mickey Mouse, the Eolopile was the most famous of the steam-powered devices created by Greek-Egyptian inventor and engineer Heron of Alexandria after he copied the idea of the steam engine from Egyptian priests' tricks and stratagems. Meant to demonstrate the concept of a steam-engine and do little else, the Eolopile was a large metal globe with two bent pipes in opposite sides, which, filled with water and placed over a fire, would spin rapidly due to the spin's violent expulsion through both outlets.

Behind the scenesEdit

The Eolopile appears in the 1957 story Mickey Mouse in Magic Land.

It is closely based on the real-life Aeolipile, popularly known as "Hero's engine" due to Hero of Alexandria (also spelled, as in Disney comics lore, Heron of Alexandria) describing its construction — although, contrary to popular belief, he did not actually invent it. (The name "Aeolipile" has been spelled "Aeolipyl", or "Eolipile", but "Eolopile"" appears to have been a mistake on George Crenshaw's part.)
