Astro-Challenge: Adventures in Daytime Astronomy
It's one of the stranger observations in ancient literature.
A curious account comes to us by the 1st century AD Roman scholar Pliny the Elder, concerning the exploits of Greek philosopher Thales of Miletus, who notes that:
"The Sun's radiance makes the fix'd stars invisible in the daytime, although they are shining as much as in the night, which becomes manifest at a solar eclipse and also when the star is reflected in a very deep well."
