Eusebius, Hist. Eccles. 1. x. c. 2, 3, 4. The bishop of Caesarea, who studied and gratified the taste of his master, pronounced in public an elaborate description of the church of Jerusalem (in Vit. Const. 1. iv. c. 46). It no longer exists, but he has inserted in the Life of Constantine (1. iii. c. 36) a short account of the architecture and ornaments. He likewise mentions the church of the Holy Apostles at Constantinople (1. iv. c. 58).
