The result of more than three decades of dedicated scholarly research by the Forschungsstelle Gregor von Nyssa (Münster), the Lexicon Gregorianum constitutes the most comprehensive Greek-German dictionary ever of the language used by Gregory of Nyssa. It is, and will be for the foreseeable future, the only dictionary available specifically addressing the vocabulary of late Classical Greek.

Far from being a simple word list, this seminal reference work documents Gregory's complete vocabulary, taking account of the syntax, meaning and connotations of every occurrence of a key word in his writings.

The complete Lexicon Gregorianum Online will comprise 10 volumes, totaling more than 13,000 entries.

The Lexicon Gregorianum Online is an technologically advanced, indispensable tool for all philological, philosophical and theological research on Gregory of Nyssa, the Greek Church Fathers, Church history and Late Antique thought.
