Yes I've read the article on UESP
. It doesn't answer this question. I'm aware that it does say the Elder Scrolls both don't exist and have always existed, but that comes from Paarthurnax in Skyrim, who loved being unnecessarily vague (and freely admitted he was avoiding direct answers to keep you talking for longer) so I'm not convinced that means there wasn't a point where the scrolls first came to be, or at least first appeared within the Mundus.
But I can't find any mention of when or how that happened. Were they created by elves, men or some other race? Or were they created by something else and elves or men discovered them? Either way, when did that happen? There must presumably have been a time before the races of Tamriel knew about the Elder Scrolls, and a point where they were created, summoned, sent, discovered or whatever and then men and elves learned how to read and use them. But everything I can find seems to skip over all of that and just focus on how and why they're used and what they say.
I suppose the simple question is: What is the earliest chronological mention of the Elder Scrolls?
