by Roderick Webster (Author)

Editorial Reviews

Product Description
The astrolabe was the most sophisticated astronomical instrument of the pre-telescopic age, and one of the most beautiful instruments of any age. Combining a simple observational tool with an elegant analogue computer, it was used for everything from time-telling to surveying, from casting a horoscope to converting among equatorial, ecliptic, and horizon coordinate systems. It was also one of the finest products of mathematically informed craftsmen. In medieval and Renaissance Europe it was emblematic of the astronomer's profession, and often of a nobleman's erudition. In the Islamic world it aided travelers with their daily prayers. Today astrolabes are among the most highly prized instruments of early science.

The Adler Planetarium & Astronomy Museum in Chicago is home to one of the world's three or four great collections of astrolabes. In this volume Roderick and Marjorie Webster, Adler Curators Emeriti, present the Western astrolabes from the Adler's collection. The earliest of these instruments dates from the thirteenth century; others are from the workshops of the greatest craftsmen of the Renaissance. All are described here and illustrated lavishly with photographs showing the front, the back, and additional details such as the maker's signature. Introductory essays by the Websters and Sara Schechner Genuth explain the use of the astrolabe and its role in cultural and social history, while the appendices and bibliography provide information essential to the specialist.

Inaugurating the multi-volume catalogue of the Adler's collection, this book lovingly documents the Western astrolabes, astrolabe-quadrants, and mariner's astrolabes at the Adler.

About the Author
Roderick Webster (1915-1997) was a foundry engineer, educated at the U.S. Naval Academy and the University of Michigan. His wife, Marjorie Webster, an archaeologist, received her education at Sarah Lawrence College and the University of California at Berkeley. Their interest in the Adler Planetarium and its collection of scientific instruments started in 1962 when they volunteered to serve as supervisors of the collection. They were volunteers for the next 35 years. From 1962 to 1969 they took care of the collection and in 1969 they were appointed co-curators. In 1991 they were named Curators Emeriti of the collection. Since then they have remained very active in the Adler Planetarium & Astronomy Museum. Both were members of many scholarly societies and traveled widely to attend meetings and study collections of scientific instruments. Roderick and Marjorie Webster served as Trustees of the Adler Planetarium, and Roderick Webster was Chairman of the Board of Trustees from 1986 to 1989.

Sara Schechner Genuth is a scholar-in-residence at the American Institute of Physics and a research fellow at the National Museum of American History. She operates a consulting business, Gnomon Research, that provides curatorial and historical support to museums, private collectors, educators, and others. From 1983 until 1990, she served as Curator of the History of Astronomy Collection at the Adler Planetarium & Astronomy Museum. She continues as a principal investigator and editor of the Adler's instrument catalogues.

He received a Ph. D. in Mathematics from New York University and has written and edited books and articles in the fields of horology, Group Theory, and the history of mathematics. He was founding editor (with Harold Edwards) of The Mathematical Intelligencer, General Editor of the catalogue projects of The Collection of Historical Scientific Instruments, Harvard University, and The Time Museum, Rockford, Illinois, and is a fellow of The New York Academy of Sciences.

5.0 out of 5 stars Alla scoperta delle radici della scienza, April 30, 2000

By	Antonio Comi (Parma (Italia)) - See all my reviews

Conoscere la scienza implicita negli astrolabi non è solo impresa scientifica, ma anche operazione culturale. Si tratta di ripercorrere le radici culturali della nostra civiltà. Padre Dante Alighieri e il suo Paradiso diverranno più comprensibili. Il cielo più affascinante.
