CHRYSORORAS, Demetrius, supposed to have been born at Thessalonica, devoted himself chiefly to philosophy and theology. Several of his works have been preserved in manuscript, including a hundred letters to the emperor Manuel Palæologus, a treatise on the procession of the Holy Spirit, a dialogue against Demetrius Cydonius, and an eulogy on St Demetrius. (See Bibliotheca Græca, tom. xi. p. 411.)
