What is the mythological origin of the word opulent?

Answer 1

The reason is seems mythological is because the Titan Opis, wife of Saturnus, is also called "Ops". The Roman and their predecessors used the same logic in naming their deities as the Greeks did. Ops, like her Greek counterpart Rhea, was a personification of the Earth, and to the Romans, all wealth and abundance came from the Earth.
