"Stellarium only allows years from -99999 to 99999 (but entering negative years is a bit tricky ... play with it). "
Okay so I don't know what the trick is to go into negative numbers - it let me go back to 00 (link and image below) but when I tried to go further it bounced me into the 1800's. Must be somewhere online where the trick that displays negative years is described.
