Descripción

Back of the Book

The author has gone through and summarized all important studies and researches done on the pillar during the last century and a half. He shows how scholarly and scientific studies have shorn the Iron Pillar of Practically all elements of Bafflement mystery and incredulity that have surrounded this ancient monument all along. He has also pointed out few gaps to be filled like the Pillar’s original location and whereabouts for some six centuries before it was installed at Mehrauli. This study can undoubtedly by termed as the most comprehensive thus far on the famous pillar.

From the Jacket

To what extent had science and technology (S&T) flourished in ancient India? Generally there are tow extreme views on this. One is that even today modern science has not surpassed what was known or practiced in ancient India. The other is that there is hardly anything worthwhile which could be claimed as ancient India’s achievement in S&T. Such Contrasting views persist because a majority of scientific ideas and technological descriptions found scatted in the old texts do not always lend themselves to unambiguous interpretation. Of course, mere references to mentions and/or pronouncements in ancient texts like the Vedas the Puranas and the epics would not be sufficient to establish unequivocally India’s scientific heritage in today’s context. These references/mentions and also the interpretations based on them need to be examined for their scientific basis and content using rigorous criteria and established methodologies of modern science. This is precisely the aim of Vigyan prasar Series of Monographs on India’s Scientific Heritage. Each publication under this series will deal with specific Indian achievements in a particular field of S&T as studied and examined critically by eminent scientists/technologists working in the field.

The present monograph is second under this series. The first one was on the Iron Pillar in Delhi. The Bronze Icons of South India particularly those form the Chola dynasty cast by the cire perdue process are known worldwide for their antiquarian value, aesthetic beauty iconography and perfection in casting. However to the discerning observes of these bronzes the most striking feature is the methodology the ancient artisans developed probably over a period of several centuries to arrive at the right combination of the metals to form the requisite alloy the procedure for casting and the repair and finishing technology.

The monograph looks at these celebrated bronze icons form both scientific and technological standpoint also laying special emphasis on the artistic accomplishments. The major challenge before scientists is to preserve this unique Indian heritage for future generations. The authors have discussed in detail about characteristics and conservation. The authors have also discussed their own investigation on some icons cast in 11th and 16th centuries in an attempt to establish procedures for fingerprinting these icons necessary for conservation. The monograph would be useful to historians artists art lovers scientists who study and analyze ancient objects and lay-persons.

Preface

It gives me great pleasure to pen these few lines by way of introduction to this second Monograph in Vigyan Prasar’s series of Monographs on India’s Scientific Heritage. Alluringly entitle as where gods come Alive this handy volume is based on a thorough scientific and technological study of the Bronze icons of South India particularly from the period of Chola Kings which are rightly admired the world over today for their aesthetic beauty sophisticated iconography and unbelievable perfection in casting as well as finishing. This study was undertaken over a period of years finishing. This study was undertaken over a period of years by a few dedicated metallurgists and materials scientist associated appropriately enough with one of India’s most prestigious and best equipped Research and Development Laboratories Viz the Indira Gandhi Center for Atomic Research (IGCAR for Short) at Kalpakam South India.

Despite their long association with the same institution viz, IGCAR the three authors of this highly informative and extremely attractive Monograph belong to three successive generations of Indian scientists and technologies. Prof. Dr. C.V. Sundaram who retired some years ago as Director IGCAR was earlier Head Metallurgy Division Bhabha Atomic Research Center (Famous nationally and internationally as BARC) Bombay and adorned until very recently the Homi Bhabha Chair at the National Institute of advanced studies, Bangalore. A Chemical Metallurgist renowned for his outstanding contributors in Nuclear Metallurgy Prof. Sundaram could encourage and motivate his younger colleagues to undertake finger printings of these precious icons mostly form the temples of Tamil Nadu utilizing the best of non-destructive testing facilities developed at IGCAR over two decades Dr. Baldev Raj now Director Metallurgy and Materials Group IGCAR was the Dynamic and inspiring leader behind these prolonged investigation on the centuries old bronze images of gods and Goddesses cast by the so called Lost wax process. Among the younger scientists Shri C. Rajagopalan of the Non Destructive testing division of IGCAR has been an enthusiastic participant in the numerous related experiments at Kalpakkam and else where. Thus it was Vigyan Prasar’s good fortune that a fine blend of experience expertise and youth could be harnessed to fashion this impressive literary edifice.

A special feature of this volume is the report on the author’s trip to the village of Swamimalai not far from Thanjavur in Tamil Nadu and on their direct observation of the age old art and science of casting bronze icons still very much alive as a traditional village vocation. The concerned families lay claim to their descent from the artisans who cast bronze icons for the famous brithadeeshwara Temple built by King Rajaraja Chola nearly a thousand years ago.

Vigyan Prasar’s grateful thanks are due not only to the three authors but also to Dr. Jawahar Dhar, CSIR Emeritus Scientist associated with the Indian national Science Academy for going through the final manuscript meticulously and giving many valuable suggestions for improving it before the actual printing.

The undersigned is beholden to Dr. Narender K. Sehgal Director, Dr. Subodh Mahanti, Editor Cum-Chief (publication) and their many colleagues at Vigyan Prasar for their continued interest and constructive involvement in bringing out this second volume of the project namely the Monograph Series on Indian’s Scientific heritage.
