If it's a natlang, then there should be more than this book as evidence of its existence. I find it strange that there are no other historical accounts of this script.

But it does raise an interesting question: Why did the author choose a catalog rather than a religious text? Maybe he was trying to preserve the language or perhaps expand its vocabulary were it a conlang.
