John Skylitzes
The merarch has sometimes been identified with Abulchares, who was appointed catapan in 1064 according to the "Anonymus Barensis". This identification is based on John Skylitzes, who makes Abulchares the Byzantine commander in 1061. In fact, the latter's dating is off and he is clearly referring to the same man as the "Anonymus" under 1064 and not to the merarch who arrived in 1060.
