Abstract

The Taktikon Escorialense, a list of functions compiled in the time of John I Tzimiskes, is an important source for studying the reform of the military organisation and state apparatus of Byzantium during the 10th century. Records of this reform, however, can also be found in other, literary and sigillographic sources, so its beginnings, principal stages and characteristics, and how the organisation of the provinces evolved in the 11th century, were reconstructed independently from the TE by Ahrweiler. Like many other sources of this kind, the TE has particular characteristics that lead one to ask in what measure this list of functions really reflected the transformation of the state apparatus in the 10th century. The conclusion may be drawn that this taktikon was an unfinished list of Byzantine functions and honorary titles, and, as indicated by data from other sources (first of all, sigillographic ones), it testifies only to a temporary phase in the reform carried out in Byzantium in the course of the 10th century. There are certain illogical elements in the TE, in the sequence of mentioning the functionaries; some data about the creation of new appointments mentioned in other sources, were omitted from this list of functions, etc. Despite the said shortcomings, though, the TE makes it possible to pose fresh questions, and reactivates some earlier ones connected with the problem of the transformation of the Byzantine central and provincial system, especially in the domain of the Empire's military organisation.
