Bharatiya Jyotihshastra (History of Indian Astronomy), translated by R. V. Vaidya v2.c15.s1.41.2

v2.c15.s1.41.2

These three words, occurring where they do, not upon the outskirts of the Hindu science, but in its very centre and citadel, amount of themselves almost to full proof of its Greek origin ; taken in connection with the other concurrent evidences, they form an argument which can neither be set aside nor refuted. Moreover, the Hindu treatises and commentaries often refer to the yavanas, “Greeks” or “Westerners,” and to “Yavanācāryas,” “the Greek (or Western) teachers” ; and floating traditions* are met with, to the effect that some of the Siddhāntas were revealed to their human promulgators in Romaka-city, that is to say, at Rome. Farther witness to the same truth, deducible from other coincidences of the two systems, we pass unnoticed here". The question relating to the days of the week has been considered before (p. 275). The *horās* and the days of the week have nothing to do with the knowledge of the true places and motions of planets, even though they did not originate with us. *Kendra* and *liptā* will be dealt with later. In conclusion Whitney observes : "The question next arises, when and in what manner the knowledge of astronomy was communicated from Greece to India. In reply to this, only probabilities offer themselves, yet in some points the indications are pretty distinct.
