Rhea is Mat(ria), Metis, Orion, married to Cronus, the time keeper. RHEA = RA, Orion.
Demeter is ''Deata > Dea > De'' plus MATRIA > MATER/METER. Thus RIA?RA/RE.
Hera is Ra in Taurus, the Age of Taurus (married to Zeus, the Bull).
Rhea, Demeter and Hera are aspects of RIA/RE/RA in various zodiac signs.
The rest of Olympians are from Atena (not Athena)'s generation - so they appear in myths with the past 2400 years.
Rhea = Orion, the Age of Orion (Anno Mundi 1 to 7,500 years ago).
Hera = Age of Taurus (c. 4,000 years ago to c. Anno Mundi 1).
Rhea = Hera = Demeter, meaning they are the same person --, RA/RIA/RE -- Matria across the zodiac.
Matria (Rhea, Hera, Demeter) is the GREAT SPHINX ..with tiger stripes sculpted on the head ...asking questions and killing the mortals who fail to answer correctly because she is MATRIA ATENA, DEATA, ultimate intelligence and wisdom, the Light that kills darkness.
