Book excerpt: The Brill Dictionary of Gregory of Nyssa is the fruit of wide-ranging collaboration between experts in Philology, Philosophy, History and Theology. These scholars shared the desire to develop a comprehensive reference work that would help attract more people to the tudy of the 'Father of Fathers' and assist them in their work. Gregory of Nyssa's thought is at once quintessentially classic and modern, as it speaks directly to the contemporary reader. As interest in Gregory has increased along with the number of works devoted to him, the need for a comprehensive introduction and bibliographical reference work has arisen. In order to meet this need, more than forty scholars from various disciplines and perspectives have contributed to this work. In two hundred articles, the Brill Dictionary of Gregory of Nyssa provides a symphonic vision of the studies on Gregory of Nyssa and his thought.
