response: The earliest autograph for a famous figure is of El Cid in 1098.
original_response: The actual oldest know autograph is back from 1098, it was the historical figure of El Cid.
history: I have over 2000 autographs. I see. That means you collected many famous people's signatures. Yeah, I wonder what this hobby is called? The hobby would be known as philography, collecting autographs. Oh I see. I wonder what the oldest one is out there? The oldest "autograph" out there is on a Sumerian table made of clay. It is dated to around 3100 BC. That's really cool to learn. Is there anything else historical about them?
knowledge: No ancient written autographs have been found, and the earliest one known for a major historical figure is that of El Cid from 1098.
