Who wrote the passage on the Poneglyph at Skypiea?


In chapter 507 the Straw Hat crew meets Rayleigh for the first time. It was
then that Robin asked whether Roger was able to understand the ancient
language used on the poneglyphs, because at Skypiea she had come across a
poneglyph with a passage written on it, supposedly signed by Roger. Yet
Rayleigh said that they were merely pirates and that Roger could not match the
intellect of those of Ohara. So then in the end, who did write the passage?

It seems that we finally know. Oda revealed in chapter 818 that...

> Oden was able to read the language and write on the stones.
