The question of the grant by the Byzantine Emperor Alexios I Komnenos of an extensive series of concessions to Venice in the late eleventh century has generated considerable attention among modern commentators. Of particular importance is the correct assessment of the date at which the generous privileges were awarded. Recent treatments of this subject have concluded that the traditional dating of 1082, which sets the Byzantine award in the context of the Norman attacks on Epirus of 1081-1085, is likely to be correct. This paper offers a rather different interpretation, arguing that the correct context for the concessions is in fact 1092. Moreover, it is stressed that this is the date provided on both the full versions of the chrysobull which survive in Latin translations. The paper sets out the case in support of this date on literary, palaeographical, numismatic and contextual grounds. Apart from having an impact. on analysis of Byzantium's relations with Venice in the eleventh century, this new interpretation also has important implications for our assessment of the Byzantine context for the First Crusade.
