Wouldn't the Sun have been in a different constellation 4000 years ago due to precession?

@JohnHoltz Yes, it was in the constellation of Virgo on that Gregorian date, according to my Horizons query above. But if the date is Julian, then the constellation was Leo.

Are you asking about the astronomical constellations, or are  you asking about the astrological sectors of the sky.  The question is hyper focussed, It's hard to imagine any practical use for this kind of fact.  Of course "August" didn't even exist in 2001 BC

Which calendar?  Proleptic Gregorian, or proleptic Julian?

@JamesK The concept of BC didn't exist in 2001 BC, either.

If you are asking about the [Gregorian calendar](https://en.wikipedia.org/wiki/Gregorian_calendar), then according to [this Horizons script](https://ssd.jpl.nasa.gov/api/horizons.api?format=text&COMMAND=10&CENTER=500%40399&CAL_FORMAT=B&CAL_TYPE=G&TLIST=%27BC%202001-Aug-5%2012%3A00%27&QUANTITIES=%2729%2C31%27) (made by [username_3](https://astronomy.stackexchange.com/users/16685/pm-2ring?tab=profile)), the Sun was in [Virgo](https://en.wikipedia.org/wiki/Virgo_(constellation)) on August 5, 2001 BC. If you are asking about the [Julian calendar](https://en.wikipedia.org/wiki/Julian_calendar), then according to [Universe Today](https://www.universetoday.com/18719/sun-constellation-1/#:%7E:text=But%20have%20you%20ever%20wondered,Sun%20technically%20has%20no%20constellation.), the Sun is in [Leo](https://en.wikipedia.org/wiki/Leo_(constellation)) in August, and hence would have been there on August 5, 2001 BC.
