So I came into watching SU about 2 weeks ago and marathoned the entire thing with in the first 2 days of watching. Since then I have been delving into just about everything that I can about this show.
That being said I think I just come to a 'theory' about the overall homeworld hierarchy arc. But first, how I came to this theory. I was thinking that every if every gem on homeworld has a specific task to be done (Quart-warrior Peridot-engineer ect.) then what do Lapises (Lapii?) do? People I've seen answer with that of a teachers or libertarians, do to her role in Mirror Gem and her stone be associated with that of knowledge. But then why do gems, a race that are created at maturity at 'birth' and, presumably, know what they should do as long as they have been told, with a guidance from some leader figure, need teachers? Also, why wings? Answer, Lapii are messengers, they can travel through space quickly (as she was able to get to homeworld in less than a year) on their own and give information. Which makes Lapii winged messengers, they are essentially Hermes of homeworld and this got me thinking.
1. Lapis in John Lennon glasses acting like Paul Shaffer is a hilarious mental image
2. If I'm right about this Greek God thing then there are many parallels to be made.
Sapphire's cycloptic future vision much like the Fates/Graeae and the cyclops that traded his eye to see the future. The architecture of the sea/sky spires and the Sky arena.
Not only that but we could easily assume things about some of the characters based on this. Blue Diamond is like that of Athena, as for the two characters that followed her are associated with knowledge and wisdom (Sapphire and Lapis). Yellow Diamond as Ares, as she's willing to destroy a planet for a weapon, and fight a war against Pink Diamond (as Jasper said that she fought Rose's arms for in the first war for earth). Pink Diamond of Artemis or Hera, for her love of the earth and willingness to protect it with her life. And what little we know of White Diamond I can only assume as Zeus, but lack any actual anything to back this up other than her diamond is always on top in the Sky arena.
