50. See Panegyr. Vet. ix. [viii.] 2. Omnibus fere tuis Comitibus et Ducibus non solum tacite mussantibus, sed etiam aperte timentibus; contra consilia hominum, contra Haruspicum monita, ipse per temet liberandae urbis tempus venisse sentires. The embassy of the Romans is mentioned only by Zonaras (1. xiii. [c. 1.]), and by Cedrenus (in Compend. Hist. p. 270 [ed. Paris; vol. i. p. 474, ed. Bonn]); but those modern Greeks had the opportunity of consulting many writers which have since been lost, among which we may reckon the Life of Constantine by Praxagoras. Photius (p. 63) has made a short extract from that historical work.
