Chronicon (Jacob of Edessa)
The Chronicon of Jacob of Edessa (full title: The Chronicle which is a Continuation of that of Eusebius) is a universal history combining biblical history, classical chronology, and contemporary events, written in the Syriac language in the 7th century. Jacob, a Syriac Orthodox monk and bishop, worked on the Chronicon until 692 AD, and it was completed by one of his students around 710, after his death. Jacob's Chronicon served as the continuation of the earlier Chronicon of Eusebius (died 339), serving to cover the three and a half centuries that had transpired since his death. The document is lost, and its reconstruction is based on a fragmentary manuscript (British Library Additional MS 14,685) and quotations of the work by Michael the Syrian and Elijah of Nisibis.
Jacob's Chronicon, though lost, had a lasting influence on Syriac historiography, and informed chronicles from later periods, such as the Chronicle of Zuqnin. The work was also used by later medieval Syriac historians, such as Michael the Syrian and Elijah of Nisibis.
