I recently learned that ἥλιος is the ancient Greek word for sun, and of course this got me thinking about the poem at the beginning of Days of Future Passed, which invokes the mythological figure with the same name: "Brave Helios, wake up your steeds."
In thinking about the poem, I realized that there's internal rhyme in the line "The mighty light of ten thousand suns" and that the repetition of -ight helps indicate that strength.
