Distortions of the Sun. 17th century diagram of the Earth explaining how the disc of the Sun appears distorted when seen close to the horizon. This effect, attributed to differential refraction, was first noted and explained by Scheiner. Line LI is the Tropic of Cancer, and line KM is the Tropic of Capricorn This woodcut illustration comes from Refractiones coelestes" by Christoph Scheiner, published at Ingolstadt in 1617."
