The extant work which goes under the name of the ‘Chronicle of Pseudo-Zachariah’ is a copy or, more probably, an abridgement, in Syriac and originally in twelve books, of a chronicle or ecclesiastical history of the eastern Roman empire from the 440s to the middle of the sixth century composed in Greek in 568/569 with an anti-Chalcedonian bias, which contains a large amount of valuable historical information. Books iii–vi, which narrate the reigns of the emperors Marcian, Leo and Zeno replicate, apparently with little change, the Ecclesiastical history of Zacharias of Mytilene (CPG 6995), the friend and biographer of Severus, who was the dissident bishop of Antioch from 512 to 518, while books vii–x, which narrate the reign of Anastasius and the early years of Justinian (down to 536/537), reproduce, and presumably copy closely, equally excellent sources for the period from 491 onwards. (The fragmentary book x, the lost book xi and the fragmentary book xii presumably went down to the death of Justinian in 565.) Pseudo-Zachariah is therefore of central importance for modern historians of the early Byzantine period, so that it is most welcome to have a modern annotated English translation of the edition by E. W. Brooks in the Corpus Scriptorum Christianorum Orientalium lxxxiii–lxxxiv=Scriptores Syri ³ 5–26 (Paris 1919–21), which was accompanied only by a Latin translation (CSCO lxxxvii–lxxxviii=Scriptores Syri 41, 42 [Paris 1924]), made by a group of excellent scholars and preceded by an introduction which discusses both the extant text and Zachariah of Mytilene helpfully and at length. For good and obvious reasons the largely unhistorical sections which occupy the whole of the first two books and the beginning of the third are not translated in their entirety, as is the rest of the work (pp. 95–455); instead they are summarised and analysed, but translated only in part (pp. 75–92).
