Bharatiya Jyotihshastra (History of Indian Astronomy), translated by R. V. Vaidya v2.c12.s2.t40: Vāvilāla Koccannā

v2.c12.s2.t40.1

A karaṇa work by Vāvilāla Koccannā, a Teḷanganā astronomer, belongs to Śaka 1220; and the epochal positions in it are given for the afternoon of Thursday, the New Moon day of Phālguna of Śaka 1219. I have calculated the planet’s places from the modern Sūrya Siddhānta, and they agree with the author’s places completely. It, therefore, clearly shows, that the work has been compiled with the help of the modern Sūrya Siddhānta. The work does not contain the correction to be applied to Sūrya Siddhānta according to Makaranda and other works. Mr. Warren, an European of Madras, compiled a work entitled ‘Kāla Saṃkalita’ in 1825 A.D. It incorporates the major part of this Karaṇa work and gives some information about it. It appears from this that the work is still in use in Teḷanganā, and almanacs are prepared with its help. These almanacs are known as “ Siddhānta Cāndra-Pañcāṅga.”
