co-authored with Peter Isépy, Cyril’s Glossary as a Source for Ps.-Zonaras’ Lexicon

On the basis of new material, the present article aims to re-examine the date of origin of the so-called Lexicon Tittmanianum or Lexicon Ps. Zonarae, and the identity of its author. Moreover, in the case of one of its numerous sources, the so-called Lexicon Cyrilli, the article aims to determine the version of the ‘Cyril’ Lexicon from which the Lexicon of Ps.-Zonaras originated. In the light of our research, which shows a connection with a branch of the Cyrillic tradition that widely circulated outside Constantinople during the Latin occupation, the origin of the Lexicon Ps. Zonarae in the first half of the 13th century in the Greek East, i.e. in the Empire of Nicaea, seems quite probable.
