Question

What might have been the measures taken by our
ancestors to ascertain time at night?​

Answer 1

Answer:

Telling time during the night needed a new strategy where relying on shadows wasn't an option. The Egyptians developed the first astronomical tool, the merkhet- a string with a weight to measure a straight line. Astronomers would align two of these with the North Star and mark a north- south line.

Answer 2

Answer:

Explanation:

A candle clock was used by ancient Chinese to measure time at night time; a candle with uniform dimension was used to measure time as the rate at which it would burn for every hour was constant, so markings were made for every inch or so to measure time.
