This is the critical edition of the earliest extant Byzantine world chronicle, the Chronographia by Ioannes Malalas (Malalas' = Syrian for 'rhetor' or 'scholar'). Iohannes Malalas was born approximately in 490 in or near Antiochia and died approximately in 570/580. He wrote his chronicle in the contemporary colloquial Greek. The edition comprises the Prolegomena which give information about the handwritten tradition of the Chronographia, the edition of the text with a rich apparatus fontium and a precise apparatus criticus as well as the indices planned in the CFHB. The edition replaces that one of Dindorf (1813 in the corpus of Bonn). It offers a more complete text in so far as it contains for the first time the first book and uses the translation of the Slavic Church in the 10/11th century for the textual construction.
