India has a strong and ancient tradition of astronomy, which seamlessly merges with the current activities in Astronomy and Astrophysics in the country. While the younger generation of astronomers and students are reasonably familiar with the current facilities and the astronomical research, they might not have an equally good knowledge of the rich history of Indian astronomy. This particular volume, brought out as a part of the Platinum Jubilee Celebrations of Indian National Science Academy, concentrates on selected aspects of historical development of Indian astronomy in the form of six invited chapters. Two of the chapters – by Balachandra Rao and M.S. Sriram – cover ancient astronomy and the development of calculus in the ancient Kerela text Yuktibhasa. The other four chapters by B.V. Sreekantan, Siraj Hasan, Govind Swarup and Jayant Narlikar deal with the contemporary history of Indian astronomy covering space astronomy, optical astronomy, radio astronomy and developments in relativistic astrophysics. These chapters, written by experts in the field, provide an in-depth study of the subject and make this volume quite unique.

The Siamese Manuscript holds the distinction of being the very first document relating to Indian Astronomy to reach Europe in a pristine form. Some fragments of Indian Astronomy had undoubtedly reached Europe in earlier times, but those tidbits were likely received in a highly altered form due to difficulties in translation, and the so-called cultural barrier. The Siamese Manuscript helped overcome this barrier by being a compendium of Indian astronomical knowledge in plain Siamese. The timing of the arrival of the manuscript in Europe was significant. After a couple hundred years the Renaissance was finally bearing fruit, and European intellectual prowess was at a peak. The deeper principles of Indian Astronomy, which had gone over the heads of the Greeks and the Arabs who first encountered them, could now be fully understood and appreciated for the first time by people outside India.

Indian scientific achievements in the early twentieth century are well known, with a number of heralded individuals making globally recognized strides in the field of astrophysics. Covering the period from the foundation of the Asiatick Society in 1784 to the establishment of the Indian Association for the Cultivation of Science in 1876, Sen explores the relationship between Indian astronomers and the colonial British. He shows that from the mid-nineteenth century, Indians were not passive receivers of European knowledge, but active participants in modern scientific observational astronomy.

This volume presents a collection of some of the seminal articles of Professor K. S. Shukla who made immense contributions to our understanding of the history and development of mathematics and astronomy in India. It consists of six parts: Part I constitutes introductory articles which give an overview of the life and work of Prof. Shukla, including details of his publications, reminiscences from his former students, and an analysis of his monumental contributions. Part II is a collection of important articles penned by Prof. Shukla related to various aspects of Indian mathematics. Part III consists of articles by Bibhutibhusan Datta and Avadhesh Narayan Singh—which together constitute the third unpublished part of their History of Hindu Mathematics—that were revised and updated by Prof. Shukla. Parts IV and V consist of a number of important articles of Prof. Shukla on different aspects of Indian astronomy. Part VI includes some important reviews authored by him and a few reviews of his work. Given the sheer range and depth of Prof. Shukla’s scholarship, this volume is essential reading for scholars seeking to deepen their understanding of the rich and varied contributions made by Indian mathematicians and astronomers.

Throughout the Indian subcontinent there are territories and areas wherein culture, geography, and the archetypal cosmos interact with each other to create a sacredscape that is infused with meaning, cultural performances and transcendent power. These sacred sites possess extensive mythological associations where believed that spirit can cross between different realms. In a broad perspective such studies falls within the realm of cultural astronomy, which has two broad areas, viz. archaeoastronomy, concerned with the study of the use of astronomy and its role in ancient cultures and civilizations; and ethnoastronomy that studies the use of astronomy and its role in contemporary cultures. The seven essays in this volume deals with the critical appraisal of studying cultural astronomy and cosmic order and its implications in India, illustrated with case studies like heritagescape of Khajuraho, where stone speaks; manescape of Gaya, where manes come and bless the devotees; Deviscape of Vindhyachal, where goddess resorts; Shivascape of Kashi, where Shiva dances in making order; Shaktiscape of Kashi, that possesses the spatial ordering of goddesses; and Naturscape of Chitrakut, where mother earth blesses.

The mysteries of the fifth Canto of the Srimad Bhagavatam have long puzzled students of Vedic cosmography and astronomy. Confronted with a description of the universe that seems much at variance with the information provided by our senses and standard astronomical calculations, foreign observers and even Indian commentators from the middle ages up to the present have concluded that the Bhagavatam`s account elaborated in other Puranas must be mythological. On the other hand the same persons have been much impressed with vedic astronomical treatises the jyotisasastras which provide remarkably accurate measurements of the solar system.
