Sometimes the best attempts at understanding the universe turn out to be bad science but deserve to survive because they are simply beautiful. This fresco of the night sky painted by Francisco Gallego in 1474 is just such an example. It covers part of the ceiling of the old university library and is located just off the plaza that separates the university’s graduate school from its undergraduate campus. Working without the benefit of the explorations by Copernicus and Galileo, the artist attempted to merge myth, science, and religion by enjambing astrology and night-sky astronomy. You’ll have to wait a few minutes after entering for your eyes to adjust to the low light, but the vision is the very definition of magic.
