Astronomy and Astrology in the Medieval Islamic World
This collection of studies by Edward Kennedy looks first at questions of spherical astronomy, celestial mapping and planetary models, and then deals with astrological calculations. Throughout the author emphasises the importance of advances in mathematics for understanding the development of medieval Arabic sciences. This collection of studies based on previously unexploited manuscript sources in Arabic and Persian. They were written by authors from the 9th through the 15th centuries, whose locations reached from south China in the east through Central Asia, the Middle and Near East, and North Africa, to Spain in the west. The topics are predominately astronomical rather than astrological. The former include eclipse predictions, problems in spherical astronomy, non-ptolemaic planetary theory, and the achievements of Ulugh Beg and his observatory. Astrological subjects treated are the method of calculating the ascendant, and how to determine astrological houses and lots. An astrological history of the career of Genghis Khan is also described.
A Survey of Islamic Astronomical Tables
The source material for the study of medieval oriental astronomy consists of Byzantine Greek, Sanscrit, Hebrew, Arabic, Persian, and Turkish astronomical and astrological manuscripts. If one desires to build up a detailed picture of Islamic astronomy, one can choose material from these available manuscripts. Of these manuscripts it is possible to isolate a group of works, the "zijes". A "zij" consists of the numerical tables and accompanying explanation sufficient to measure time and to compute planetary and stellar positions, appearance, and eclipses. This paper is a survey of the number, distribution, contents, and relations between "zijes" written in Arabic or Persian during the period from the 8th through the 15th centuries. Illustrations. Oversize.
Edward Kennedy
In this groundbreaking biography of Edward Kennedy, historian and journalist Burton Hersh combines a lifetime of research and reporting with a lively mixture of never–before–told anecdotes (including the definitive version of the incident at Chappaquiddick, the details of which Kennedy himself filled in for Hersh shortly after it occurred) to create a broad yet unfailingly intimate portrait of the politician who would be universally acknowledged as one of the twentieth century's greatest American legislators. Hersh was acquainted with Kennedy since his college days, and the result here is a unique series of revelations that serve to reinterpret the senator's public and private personas. ...
The Melon-shaped Astrolabe in Arabic Astronomy
The astrolabe was for many centuries the most popular of all astronomical instruments. Invented during the Hellenistic period, it proliferated in medieval times, especially in the lands of Islam and consequently also in Europe. The melon-shaped astrolabe is a special form of astrolabe. Unlike the commonly known planispheric instrument, it does not depend on stereographic projection. A description of its principles is to be found in the introduction and in the texts edited here. Making the instrument required elaborate mathematical procedures, which are themselves of considerable historical interest. Presented here are extended texts by Habash al-Hasib (9th century) and al-Biruni (d. 1048), t...
