Caesarius of Nazianzus
Caesarius Of Nazianzus, a younger brother of Gregory Nazianzen, was educated first at Alexandria, whence he proceeded to Constantinople, where he obtained high honors, resisted the attempts of the Emperor Julian to win him from the faith, and died under Valens in 368. He was distinguished for his proficiency in physics and mathematics. Gregory delivered his funeral sermon (Oratio funebris in laudem ,Caesarii fratris, Or. 8), in which his piety and devotion are lauded. According to Suidas, he wrote contra Gentes, and four Dialogues are given as his in the Latin editions of St. Gregory and in the Bibliotheca Patrum. — Ullmann, Life of Gregory, p. 132; Cave, s. a. 362.
