>>42280073 (OP)Celestia is worshipped as a motherly sun-bring deity, but when she was born it would make sense for her name to match her standing; thus, a Romanized Praenomen commemorating her birth during the morning light, and a feminine version of a Nomen commemorating Faust. It would then make sense for her to list her many titles as apart of her Cognomen, slowly becoming her Nomen as time wore on; Titles I can fathom would include: Separate titles for her takeover of each respective tribe, her modern name in title form, a title to commemorate her moving the sun, a title to commemorate her mother's ascendancy to godhood---for various political reasons---a title to commemorate piety---and before that a more modernized version of her Praenomen---a title to commemorate her duty to the sun, titles to commemorate her eternal tribunehood, and consulship, and a title to commemorate her mother-like nature regarding the state. Now we move on to true Cognomen, titles gained through military action and deeds, one should commemorate her defeating the three tribes, and thus conquering them, another to commemorate her destroying the Alicorn Cult---whom worshipped her as a god---permanently, and a last to commemorate her military actions against griffons. Now we move on to more modern titles, those garnered during the medieval stage of Equestrian history; From a human standpoint these would make most sense to be Greek names, but the Byzantines had a great desire to be named Christianly, so one must decide in their own fanon whether a monotheist cult replaced the Alicorn Cult after it's destruction within Equestrian history. I am in favor of this---to make the name longer---thus begins Celestia's monotheistic names---Due to the differences in the Byzantine court and the Roman court, Celestia would only be referred to by her Greek names, as her Roman ones are extremely heretical---Early monotheistic names to replace her Praenomen, her title to begin her Nomen, a Greek version of her original Praenomen and Nomen respectively, her title to commemorate her being, 'born-in-the-purple,' and then various monotheistic names beginning with, "Theo," to commemorate her various duties to the monotheistic God which exists in Equestria. Finally ending in her title, now become name, similar to, "Caesar;" But since Caesar is technically Celestia it would be a mesh of the two names/titles, thus ending her Greek name.
Due to my autism it is my belief this is Celestia's full name:
