Answer:
Eratosthenes observed shadows cast by a vertical stick during the noon time in the summer solstice.
Explanation:
Eratosthenes, one of the first to believe in the spherical Earth theory, tried to prove his belief in the same by measuring the radius of the Earth. In an attempt to do so, he measured the shadow of a vertical stick during the noon of the summer solstice. This enabled him to find the primary Earth's radius estimation by observing this, followed by a series of calculations using a set of formulae.
