Abstract It is well known that the historical texts composed under the Macedonian dynasty (Theophanes Continuatus, Genesios, but also Leo the Deacon, Manuel protospatharios, John Skylitzes or even Michael Psellos) display certain element, which can be seen as attempts to make a clean break with the past; the formalist style of unbroken historical narrative was largely rejected in favour of historical biography in which the influence of rhetorical methods is self-evident. It is not known which criteria tipped the balance in favour of such a development, though we would do well to consider both the influence of Antiquity, and the close ties that bound biography to hagiography, which from the empire's very beginnings (Vita Constantini) also served as a uniquely Byzantine mode of promoting the image of the emperor. It may be legitimate to speak of a new type of historical writing which is specifically designed for the extremely beautified career of its subject and constitutes a contemporary movement which manifested itself in various cultural contexts.
