Note the Ionic ending -ης. This grammatical form is used in many Byzantine texts (Psaltes, Grammatik, 143). Zacos-Veglery (no. 2078b) have published seals of the same individual but from a different boulloterion. Cf. DO Seals 2, no. 8.6.

The island of Euboia, lying off the northeast coast of Boeotia, retained its ancient name in the Middle Ages; it also went by the name of its capital, Euripos. See ODB II, 736-37; Koder-Hild, Hellas, 46; and Koder, Negroponte, 63.
