註釋
The main purpose of this work is to obtain and assess a large body of observations of solar eclipses from medieval records (roughly the period from 400 to 1200), and to use the observations in improving our knowledge of the motion of the solar system. Catalogues of various types of data are given in the appendices including but not limited to lunar eclipses, comets, novae, famines, and earthquakes.
