Is it possible to see stars in the daytime from the bottom of a deep and narrow shaft?

No, it was actually fairly far from the Little Dipper at that time. Here is a chart of the axial precession over time. The pyramids were mostly built between 3000 and 2000 BC. Thuban is the star that was quite close to the pole in 3000 BC, and it was close enough for that role for about 600 years on either side of that date.

Obviously IDNRC. Thanks for the correction.

Vega, the fifth-brightest star in the night sky, also sometimes takes a turn as the Pole Star. During those times, it must be really hard to convince people that the pole star isn’t the brightest star.
