The work is very much shorter than the
Chronicle of 754. It contains little Spanish history; the first 14 sections contain very brief mentions of the
Visigothic kings up to the reign of
Suintila (621-631), taken from the
Historia de regibus Gothorum, Vandalorum et Suevorum of
Isidore of Seville. The remainder of the content consists of alternating sections dealing with the
Byzantine Emperors and the parallel leaders of the Arabs beginning with
Muhammad. These sections perhaps derive from the
Chronicon Mundi of
John of Nikiû and from Arabic or Syriac works which have not survived. Some of these sections contain very brief mentions in passing, of the
Arab invasions of North Africa, Spain, France, and parts of the Middle East. Little if any of the content is original; the value of the work lies in what it reveals of the author and his times. ==Author==
