Pronunciation

  • IPA: /ˈiːd͡ʒɪs/[1]

Etymology

It is borrowed from Latin aegis,[2][3][4][5] from Ancient Greek αἰγίς (aigís, “the shield of Zeus”),[2][6][3][4] probably from Ancient Greek αἴξ (aíx, “goat”) (stem aig-),[2][6][4][5] since the shield was made of goatskin.[6][5] The Greek goat word comes from Proto-Indo-European *aig- “goat”.[6]

Earliest recorded meaning

The shield of Zeus or Athena, or of their Roman counterparts Jupiter and Minerva (1581 in Merriam-Webster; 1611 in Barnhart).[4][2][1]

Semantic evolution

In myth the aegis was a protective attribute, Athena's being a goatskin cloak set with a Gorgon's head;[6][3][5] so to be under someone's aegis came to mean being under their protection.[2][6] The figurative sense is first recorded in 1793.[2][6] In the 20th century the meaning widened to sponsorship or patronage, as in under the aegis of the museum.[3][4][5]
