#1 When did Superman start using the exclamation "Great Rao!", or mentioning Rao as a diety, generally?
Related to this - when did we find out that Krypton's sun was called Rao?
#2 I recently picked up John Ostranders 1995 Gotham Nights II 4 issue miniseries, set largely on Paris Island, an amusement park located off the coast of Gotham (or in the Bay, or whatever.)
When was this 'Paris Island' first mentioned?
Rao's name is used as the kryptonian name for God in the wedding sequence at the end of the marriage of the Earth Two Superman story in Action Comics #484.
Yeah Gotham seems to have a lot of islands that appear and disappear with regularity. One of the magicians should really look into it.
I'd be curious as to the first appearance of Blackgate Prison. We always saw Arkham Asylum -- which I believe is an early '70s development -- but it stands to reason that there ought to be a garden-variety penitentiary for those Gotham-area crooks who aren't crazy.
According to the The Krypton Chronicles mini (1981) Rao was originally a sun-god, but he was later reinterpreted monotheistically (by a prophet named Jaf-El) and dis-identified with the sun. In the marriage rite depicted in Action Comics #484 the marrying couple invoke Rao, the maker of the sun and moons, while exchanging bracelets. The final issue of The Krypton Chronicles depicts an earlier form of the rite in which the couple invoked "the glory of Rao, the sun" and "the mistress of the moons, Yuda" while exchanging bracelets "representing our two moons".
