Siddhantasiromani of Bhaskaracarya (English Exposition and Annotation in the light and language of modern Astronomy along with original text in Sanskrit)

It is a matter of great satisfaction and pride that keeping with its tradition the Rashtriya Sanskrit Vidyapeetha, Tirupati, has been able to bring out the revised edition of the English Exposition and Annotation of Jyotisha text, the Siddhantasiromani of Bhaskaracharya, one of the renowned astronomers that the medival India produced. The English Exposition and Annotation was authored by Dr. Arka Somayaji an erudite scholar in Jyotisha, who served this Institution with dedication for several years. Since the first edition of this work contained only the English Exposition and Annotation, it was felt that it will be more useful if the original text is also added. Hence the present edition contains the original Sanskrit work.

I am sure that the students and as well the scholars of Astronomy will equally be benefited by the present edition.

I shall take this opportunity to express sincere thanks to Prof. S.B. Raghunathacharya, former Vice-Chancellor of this Vidyapeetha, who during his tenure took the initiative to bring out this edition. I also thanks the members of the staff of the Research Department of this Vidyapeetha without the best efforts of whom the present edition would not have come so superbly.

Publisher's Note

The Vidyapeetha has been publishing a number of books on Veda and Sastra subjects over the past 30 years. The English Exposition and Annotation in the light and language of modern Astronomy on Siddhantasiromani of Bhaskaracharya by the illustrious scholar Dr. Arka Somayaji ws published by the Vidyapeetha in 1980. The book has earned the appreciation of the scholars of repute in the field of Jyotisha.

Dr. Arka Somayaji was born in a traditional Vedic scholars' family. He was a great scholar in Sanskrit, Srouta Sutras, Astronomy and Mathematics. Besides his traditional background Dr. Somayaji had a modern outlook on the dissemination of Veda and Sastra knowledge. He authored many works.

The Siddhantasiromani, now being published, is a revised edition of the first print by Dr. Somayaji. The very fact that the copies of the book were sold out in a very short time and that it has been in constant demand, itself speak volumes of the great scholarship and the authority on the subject of the editor.

Keeping in view the great demand for the precious book the Vidyapeetha decided to reprint it. It is a matter of great pleasure that the task could be completed in a short time. It is earnestly hoped that the revised print of the Siddhantasiromani will be received with appreciation by the scholarly world.
