What is an Aeolipile?

An Aeolipile
Special thanks to George P.
from Ottawa for the tip.
According to a NASA kid's site on the history of flight, an aeolipile is an ancient Greek invention demonstrating one of the first examples of steam power.
This was another of Mad's seemingly endless examples of repeating obscure images or words from issue to issue for no apparent reason but to add texture or confusion to an already dense magazine. Below are five examples from five different issues.
