aegis: [18] The notion of ‘protection’ contained in this word goes back to classical mythology, in which one of the functions or attributes of the Greek god Zeus (and later of Roman Jupiter or Minerva) was the giving of protection. This was usually represented visually as a shield, traditionally held to be made of goatskin – hence Greek aigís, the name of the shield, came to be associated in the popular imagination with aix (aig- in its stem form), the Greek word for ‘goat’. English borrowed the word directly from Latin.
[aegis etymology, aegis origin, 英语词源]
aegis (n.)youdaoicibaDictYouDict
"protection," 1793, from Latin aegis, from Greek Aigis, the name of the shield of Zeus, said by Herodotus to be related to aix (genitive aigos) "goat," from PIE *aig- "goat" (cognates: Sanskrit ajah, Lithuanian ozys "he-goat"), as the shield was of goatskin. Athene's aigis was a short goat-skin cloak, covered with scales, set with a gorgon's head, and fringed with snakes. The exact use and purpose of it is not now clear.
The goatskin would be worn with the two forelegs tied in front of the wearer's breast, or possibly with the head passed through an opening made at the neck, by the removal of the animal's head. [F. Warre Cornish, ed., "Dictionary of Greek and Roman Antiquities," London, 1898]
