Rhea was the daughter of Uranus and the mother of Zeus, a titaness of Greek mythos.  Beginning as an all-female krewe, Rhea has been a popular part of the pageantry in Jefferson parish from its inception.  Besides being the first krewe to roll along Veterans Memorial Boulevard in Metairie,  for several years it was one of the only krewes from the suburban realms to stage its balls in the Municipal Auditorium in the city proper.  Each year a special celebrity guest rides with the Rheans.  The krewe features a series of family floats, mini-floats for the ladies of the court and the officers, and a special streetcar float for the ladies-in-waiting.
Rhea leads the way for what is now known as Super Parade Sunday in Jefferson Parish, an event that nearly eclipses the crowds in Orleans Parish on Mardi Gras Day.

This krewe shares a Greek theme with the krewes of Adonis, Aphrodite, Argus,  Atlas,  Endymion, Hermes,  Iris,  Jason,  Morpheus,  Muses, Okeanos,  Orpheus,  Pegasus, Proteus,  Morpheus,  Pygmalion,  Sparta, and  Zeus.
