Bharatiya Jyotihshastra (History of Indian Astronomy), translated by R. V. Vaidya v2.c15.s2.4

v2.c15.s2.4

Copernicus compiled his work in Śaka 1465. Prior to this date European astronomy was practically in the same condition as astronomy in India. The great difference between the two, however, was that the European science was progressive while ours was stagnant. It was not very long before Copernicus, that Gaṇeśa Daivajña and his father Keśava Daivajña, both of them research-loving scholars, were flourishing in our country. But with the advent of Copernicus, European astronomy passed through such a tremendous change that while the science of the by-gone days was comparable to the newly grown sapling of the Banyan tree, the latter-day-science was the Banyan tree itself, towering in the full-grown majesty of centuries, yielding shade and shelter to thousands. Ours has merely clung to the status quo ante .*
