Chronographiae quae Theophanis Continuati nomine fertur Liber quo Vita Basilii Imperatoris amplectitur

The life of Emperor Basil I (867–886), the founder of the Macedonian Dynasty, is the only extant secular biography in Byzantine literature; in its importance and as an instance of the genre it is comparable to Einhard’s Vita Caroli Magni. Composed in the circle of scholars around Basil’s grandson Constantine VII Prophyrogennitos and at his instigation as early as 957 and 959, the Vita Basilii is one of the main sources for the cultural and political history of Byzantium and its neighbours in the 9th and 10th centuries. Previous editions (whether from the 17th or 19th centuries) were based on secondary manuscripts; they are not reliable, because of their arbitrary conjectures and a large number of unjustified additions from a parallel source. The present edition is based on Vaticanus gr. 167, the source of all extant manuscripts, and the insertions made by the earlier editors are removed. In producing the new text, the editor also had access to the draft edition he rediscovered which the famous Byzantinist Karl de Boor prepared around 1903.
