Notes on Some Less Familiar British Astronomical and Astrological Manuscripts
No TL;DR found
Abstract
The following notes are primarily, although not exclusively, concerned with manuscripts seen in the summer of 1957 at the British Museum, London, and Bodleian Library, Oxford. At first the treatment will be topical, considering such matters as the time of the vernal equinox, astronomical terminology, calendars and eclipses, computus, mansions of the moon, lists of fixed stars, signs of the zodiac, position and movement of the sun, astronomical tables, and weather prediction. Then, after noting two manuscripts of Thebit ben Corat, a so-called Summa astrologia, and identifying a so-called Liber astronomicus, three astrological manuscripts will be described, and a fourth composite manuscript, of which the first component is astrological, and the third and last component, astronomical.
