Ægis, Greek mythology.
The goatskin breastplate or shield of Zeus(King of the gods) or Athena (goddess of wisdom). The shield, Ægis, when carried by Athena has the head of Medusa, retaining its powers of petrification, attached to the center.

The shield offered protection and security - to be under the ægis of someone, or something, is to be under its protection.
In WWII, foreign ministers entered warring territories under the ægis of diplomacy.
