To be under the aegis of someone means to have their financial or moral support or to be sponsored or protected by them. 1,2

The idiom under the auspices of someone is used in exactly the same way.

"You are here under the auspices of Mr. Franklyn, but you must still pass a probationary period like everyone else," said Fran's new boss.


c. Late 1700's 1

The aegis, in early Greek myth, was the storm cloud surrounding the thunderbolt of Zeus. Later, it became the protective shield and/or armor of Zeus and then of Athena, said to be built by the fire god Hephaistos from the hide of the goat Amaltheia. 3,1

The term auspice has the same protective connotation as aegis, today. Interestingly, in ancient Greek, the term aspis, -idos meant a small shield for battle. However, the modern term derives from the Latin avis for bird and spectre, meaning "to see." Originally, this referred to observing birds in flight for the purposes of divination or, in other words, to look for omens to predict the future. The term later came to mean a favorable influence and then to the modern meaning of patronage or protection by an important person or institution. 4,1
