Sisyadhi Vrddhida Tantra of Lall (Set of 2 Books)

The work is issued in two Parts, Pt. I contain the Text and an old commentary thereon, and Pt. H contains its Translation with Mathematical Notes and a number of useful Indices, including a Glossary of Technical terms.

The work of editing and translating into English of sisyadhivrddhida with critical annotations was taken up by the late Dr. (Mrs) Bina Chatterji whose scholarship in this field is already well known. While the work of printing was in progress, and 32 pages had been printed, Dr. Chatterji passed away in January 1978. After her demise, we took the help of two other scholars in the field, namely, Prof. K. S. Shukla and Prof. K. V. Sarma towards the publication of the work. They have taken utmost care in their work and have given dedicated service towards the press-processing, printing, proofreading, preparing indices etc. of the work. The Academy is indeed very grateful to these two scholars for their valuable cooperation in the work. Without their help, the work could not have been published so early. We hope that this publication also will receive the approbation of scholars like the other publications of the Commission.

The Khaodakhadyaka was published by me in October 1970 and, soon after, my study of the Sisyadhivrddhida commenced. This plan was facilitated by the timely financial assistance extended to me by the Indian National Science Academy with effect from November 1971, for which I am extremely grateful to the Academy.

The Sisyadhivrddhida had already been published by Sudhakara Dvivedi in A.D. 1886, but that edition was based only on one manuscript and could not, therefore, be called a critical edition. The present edition has been prepared after collating twenty manuscripts, of which one is from the Bodleian Library, Oxford, and another from the Statsbibliothek, Berlin (W. Germany). The remaining manuscripts are from different libraries in India. The present edition gives also the commentary by Malliknrjuna Sari, available only for the First Part. The translation provided is intended to give an intelligible rendering of the text and the Notes to interpret, in terms of modern science, the mathematical calculations involved in the textual verses.

I take this opportunity to express my gratitude to Professor David Pingree, Brown University, U.S.A., who after learning that I desired to bring out an edition of the ..isyadhivrddhida, very kindly sent me a list of the manuscripts of the work, I thank all the libraries which extended their cooperation not only by sending me copies of the manuscripts required but also by making it possible for me to visit those institutions to collect materials for my study. I am also grateful to Dr. K. S. Shukla, Professor of Mathematics, at Lucknow University, who was always ready to help me to solve my difficulties with the text. I must also mention with gratitude the assistance offered by Dr. M. L. Sharma, Head of the Department of Astronomy, Sampurnanand Sanskrit Vishvavidyalaya, Varanasi, in the matter of checking some of the examples in the commentary. My thanks are due also to Dr K.V. Sarma, Director-Professor of the Vishveshvaranand Institute, Hoshiarpur, for the wholesome suggestions and advice he gave me towards the presentation of the volume.

In all humility, I place this work before the learned world and fervently hope that in spite of its shortcomings, it will still be of some use to the study of the history of Indian astronomy.
