The vast majority of questions on this site cover recent claims, but I have not been able to find anything in the Help Center or Meta saying that a claim becomes off-topic after a certain amount of time has passed. Is there a time limit as to how recent a claim must be for it to be acceptable here?
For example, we field a lot of questions on claims made by contemporary politicians, and these sorts of claims are widely accepted as within the scope of this site. If I found a claim in the writings of Julius Caesar, a decree issued by Pharaoh Thutmose II, or a speech given by Alexander the Great, and the claim was sufficiently clear and specific, would it be on-topic, or would it be closed as too old or no longer notable?
To be clear, I'm asking in general, not asking for feedback on a specific claim that I'm thinking about posting about. I do accept that unclear or unverifiable claims of the past (e.g "I'm the smartest king in the world" or "God has cursed my enemies and blessed my upcoming victory") are not going to be acceptable regardless of how long ago they were made.
