Since you could reasonably add (1750 B.C.) to the headline, you should. What's the oldest year reference record for a successful story? I once tried "Epic of Gilgamesh (2100 B.C.)" but it got no votes.
Wikipedia entries generally don't have years added to them, as they are not the original text, but rather text about the text. If you linked to the original text (or a translation will do), then the original year makes sense (unless the translation's date is more important).
