Perseus was indeed the founder of a new dynasty at Mycenae, c. 1290 b.c., his violation of the neighboring goddess's grove must have marked the end of an ancient rite — possibly of regicide — there practiced. The myth of his miraculous birth from the golden shower of Zeus then would have been of great moment, as validating his act in terms of a divine patriarchal order of belief that was now to supplant the old, of the mother-goddess in whom death is life. Perseus, we are told, was conceived of Zeus miraculously by the princess Danae of Argolis
Campbell reads Danaë's conception by the golden shower as a mythic charter for the displacement of matriarchal goddess-religion by patriarchal Olympian authority, making Perseus's miraculous birth the ideological foundation of a new dynastic and religious order.
