Historical Hindu astronomy (Jyotiṣa) develops as a discipline of Vedanga or one of the "auxiliary disciplines" associated with the study of the Vedas. The oldest extant text of astronomy is the treatise by Lagadha, dated variously to the Mauryan era (final centuries BCE).
Indian astronomy flowered in the 6th century, with Aryabhata, whose Aryabhatiya represented the pinnacle of astronomical knowledge at the time, and significantly influenced medieval Muslim astronomy. Other astronomers of the classical era who further elaborated on Aryabhata's work include Brahmagupta, Varahamihira and Lalla.
An identifiable native Indian astronomical tradition remains active throughout the medieval period and into the 16th or 17th century, especially within the Kerala school of astronomy and mathematics.
Famous quotes containing the words indian and/or astronomy:
“A red-headed woodpecker flew across the river, and the Indian remarked that it was good to eat.”
—Henry David Thoreau (18171862)
“Awareness of the stars and their light pervades the Koran, which reflects the brightness of the heavenly bodies in many verses. The blossoming of mathematics and astronomy was a natural consequence of this awareness. Understanding the cosmos and the movements of the stars means understanding the marvels created by Allah. There would be no persecuted Galileo in Islam, because Islam, unlike Christianity, did not force people to believe in a fixed heaven.”
