Bharatiya Jyotihshastra (History of Indian Astronomy), translated by R. V. Vaidya v1.c5.18

v1.c5.18

As regards publicity of old works, it has been noticed that the Telāṅgānā and Dravidian works are not widely known in other provinces. This seems to be due to the difference of script in which they are written. The works produced in Bengal are also not available in this province. Even then, looking to the difficulties of travel and communication in ancient times, one is really surprised to see how voluminous works could reach even the remote corners of India, how works like Grahalāghava, so frequently mentioned in this book, gained currency all over the country in a very short period of time, and how even mediocre works have been popularised. This wide-spread currency of books seems to be due to the fact that astronomers used to be patronised not only by Hindu Kings but also by Muslim Emperors. Moreover, it appears that most of them could count upon liberal reception from the Vidyāpītha (Academy) at Varanasi.
