Inca Astronomy and Astrology: The History of the Inca’s Measurements of the Planets and Stars

Though the Spanish physically conquered them in quick fashion, the culture and legacy of the Inca Empire has continued to endure throughout the centuries in both Europe and South America, due in no small part to the fact they were one of the most advanced and sophisticated cultures on the continent. Like the Aztecs, the Spanish burned much of the Inca’s extant writings, but it is estimated that as many as 35 million once fell under their banner, and the empire’s administrative skills were so sharp that they kept accurate census records. Their religion, organization, and laws were also effectively centralized and tied to the rulers of the empire, and their military mobilization would have made the ancient Spartans proud. After the Spanish conquest, several rebellions in the area attempted to reestablish the proud Inca Empire over the next two centuries, all while famous Europeans like Voltaire glorified the Inca Empire in optimistic artistic portrayals.

The sun was the main element present in the Inca worldview, so Inti, the sun god, was worshipped above all others and, even though the different parts of the empire were allowed to practice their individual beliefs, they were encouraged to venerate the sun. The connection with the sun even extended to their kings since they were considered to be the sons of the sun. Naturally, this meant astronomy was a key component of the Incas’ beliefs, and in addition to the sun, the Inca observed the moon, stars, constellations, and some planets, all of which became integral parts of their cosmology. The Cusco Valley was the heart of the Inca Empire, and many of the Inca's settlements have been found to contain important astronomical elements, providing clear evidence of the importance astronomy had among the Inca.
