English borrowed the word aegis from Latin,
but it ultimately comes from the Greek noun aegis, meaning goat's skin.
In ancient Greek mythology, an aegis was something that offered physical protection.
It had been depicted in various ways,
including as a magical protective cloak made from the skin of the goat that suckled Zeus as an infant,
and as a shield fashioned by Hephaestus that bore the severed head of the Gorgon Medusa.
The word first entered English in the 15th century as a noun referring to the shield or breastplate associated with Zeus or Athena.
