Thus the Greeks called Jupiter, Supreme Mind; but having traditionally ascribed to him many base actions, they involuntarily made amends to reason, by tying up the hands of so bad a god. He is made as helpless as a king of England. Prometheus knows one secret which Jove must bargain for; Minerva, another. He cannot get his own thunders; Minerva keeps the key of them. “Of all the gods, I only know the keys That ope the solid doors within whose vaults His thunders sleep.”
The Rare Source: The line "I alone of the gods know the keys to the house where his thunderbolt is sealed" is spoken by Athena in the play "Eumenides" by Aeschylus, from the 5th century BCE. This is a very specific and unusual reference. In the play, Athena uses this statement to assert her supreme authority and to persuade a group of vengeful goddesses (the Furies) to accept a compromise.
