Sawai Jai Singh and His Astronomy


Book Description

Sawai Jai Singh the statesman astronomer of 18th century India designed astronomical instruments of masonry and stone, built observatories prepared a Zij or a text for astronomical calculations and sent a fact-finding scientific mission to Europe. His high precision instruments were designed to measure time and angles to the very limit of naked eye observing.




Celestial Mirror


Book Description

Explore the eighteenth-century Indian astronomical observatories called the Jantar Mantars, massive, stunning structures built to observe and understand the heavens Between 1724 and 1730, Maharaja Sawai Jai Singh II of Jaipur constructed five astronomical observatories, called Jantar Mantars, in northern India. The four remaining observatories are an extraordinary fusion of architecture and science, combining elements of astronomy, astrology, and geometry into forms of remarkable beauty. The observatories’ large scale and striking geometric forms have captivated the attention of architects, artists, scientists, and historians worldwide, yet their purpose and use remain largely unknown to the public. In this book, Barry Perlus’s visually driven exploration brings readers to the Jantar Mantars and creates an immersive experience. Panoramas plunge the viewer into a breathtaking 360-degree space, while pages of explanatory illustrations describe the observatories and the workings of their many instruments. The book provides the experience of visiting the sites, the historical context of the Jantar Mantars, and an understanding of their scientific and architectural innovations.




Handbook of Archaeoastronomy and Ethnoastronomy


Book Description

How human communities interpret what they perceive in the sky is vital in fulfilling humankind’s most basic need to comprehend the universe it inhabits, both from a modern scientific perspective and from countless other cultural standpoints, extending right back to early prehistory. Archaeoastronomy, which is concerned with cultural perceptions and understandings of astronomical phenomena, is a rich cross-disciplinary field. The central aim of “Handbook of Archaeoastronomy” is to provide a reliable source for theory, method, interpretation and best practices that will give a definitive picture of the state of the art research in this field for serious scholars regardless of the discipline(s) in which they are qualified. It will be equally suitable for those already contributing to the field and those interested in entering it. Also included are studies in ethnoastronomy, which is concerned with contemporary practices related to astronomy, particularly among modern indigenous societies. A major part of this MRW is comprised of a set of wide-ranging archaeoastronomical case studies both geographically and through time, stretching right back to Palaeolithic days, and also in terms of the types of human society and nature of their astronomical ideas and practices. However, these are chosen in order to best illuminate broader issues and themes, rather than to attempt, for example, to provide systematic coverage of recent ‘discoveries.’ Thematic articles cover general themes such as cosmologies, calendars, navigation, orientations and alignments, and ancient perceptions of space and time. They also highlight various aspects of the social context of astronomy (its relationship to social power, warfare, etc) and how we interpret astronomical practices within the framework of conceptual approaches. There are also discussions of broad issues such as ethnocentrism, nationalism, and astronomical dating. The “methods and practices” articles cover topics from field methodology and survey procedures to social theory, as well as providing broad definitions and explanations of key concepts. We are also including a number of “disciplinary perspectives” on approaches to archaeoastronomy written by leading figures in the constituent fields. These articles cover material that, generally speaking, would be familiar to graduates in the relevant discipline but, critically, not so to those with different backgrounds.







Searching the Heavens and the Earth


Book Description

Jesuits established a large number of astronomical, geophysical and meteorological observatories during the 17th and 18th centuries and again during the 19th and 20th centuries throughout the world. The history of these observatories has never been published in a complete form. Many early European astronomical observatories were established in Jesuit colleges. During the 17th and 18th centuries Jesuits were the first western scientists to enter into contact with China and India. It was through them that western astronomy was first introduced in these countries. They made early astronomical observations in India and China and they directed for 150 years the Imperial Observatory of Beijing. In the 19th and 20th centuries a new set of observatories were established. Besides astronomy these now included meteorology and geophysics. Jesuits established some of the earliest observatories in Africa, South America and the Far East. Jesuit observatories constitute an often forgotten chapter of the history of these sciences.

Jantar Mantar, Maharaja Sawai Jai Singh’s Observatory in Delhi


Book Description

The Delhi Jantar Mantar is an enigma. Its huge and arresting forms evoke awe even today when architecture seems to consist primarily of strange shapes and proportions. Most people who see it are left with many questions. • What is it really? • Why is it called Jantar Mantar? Is it linked to the performance of some mystical religious rites? • How were its gigantic structures made? • Do they form part of a maze? Are they forerunners of abstract art installations? • Or are they buildings? If so, what is this strange architectural style, so different from the other buildings of its time? • How, if at all, is it linked to astronomy? This informative history and fi eld guide explains all this and more. Based on over a decade of extensive research, it uses archival images, photographs, drawings and sketches, to unravel how the 300 year old Jantar Mantar Observatory looked and worked in the past. Each instrument of the Jantar Mantar is explained separately as a guided ‘walk’. The book includes information on traditional Indian astronomy, and on the political and cultural background of this ‘royal observatory’ established by Maharaja Sawai Jai Singh II. It not only traces its transformation into ‘an archaeological monument’, but also charts the way ahead by which the Delhi Jantar Mantar’s historical function may be revived and conserved for future generations. Carry this book to the Jantar Mantar and walk around the instruments with it. Or read it before and after your visit to understand one of the world’s most unusual and intriguing works of architecture.




About Time


Book Description

One of Smithsonian Magazine's Ten Best History Books of 2021 A captivating, surprising history of timekeeping and how it has shaped our world. For thousands of years, people of all cultures have made and used clocks, from the city sundials of ancient Rome to the medieval water clocks of imperial China, hourglasses fomenting revolution in the Middle Ages, the Stock Exchange clock of Amsterdam in 1611, Enlightenment observatories in India, and the high-precision clocks circling the Earth on a fleet of GPS satellites that have been launched since 1978. Clocks have helped us navigate the world and build empires, and have even taken us to the brink of destruction. Elites have used them to wield power, make money, govern citizens, and control lives—and sometimes the people have used them to fight back. Through the stories of twelve clocks, About Time brings pivotal moments from the past vividly to life. Historian and lifelong clock enthusiast David Rooney takes us from the unveiling of al-Jazari’s castle clock in 1206, in present-day Turkey; to the Cape of Good Hope observatory at the southern tip of Africa, where nineteenth-century British government astronomers moved the gears of empire with a time ball and a gun; to the burial of a plutonium clock now sealed beneath a public park in Osaka, where it will keep time for 5,000 years. Rooney shows, through these artifacts, how time has been imagined, politicized, and weaponized over the centuries—and how it might bring peace. Ultimately, he writes, the technical history of horology is only the start of the story. A history of clocks is a history of civilization.







Expounding the Mathematical Seed. Vol. 1: The Translation


Book Description

In the 5th century, the Indian mathematician Aryabhata wrote a small but famous work on astronomy in 118 verses called the Aryabhatiya. Its second chapter gives a summary of Hindu mathematics up to that point, and 200 years later, the Indian astronomer Bhaskara glossed that chapter. This volume is a literal English translation of Bhaskara’s commentary complete with an introduction.
