Its most characteristic feature was one for which it is difficult to find any more exact description than the paradoxical phrase, “a _viva-voce_ literature.” It had its birth and chief development in that part of the Empire in which Christianity and Greek life came into closest and most frequent contact. It was the product of the rhetorical schools which have been already described. In those schools the professor had been in the habit of illustrating his rules and instructing his students by model compositions of his own.[144] Such compositions were in the first instance exercises in the pleading of actual causes, and accusations or defences of real persons. The cases were necessarily supposed rather than actual, but they had a practical object in view, and came as close as possible to real life. The large growth of the habit of studying Rhetoric as a part of the education of a gentleman, and the increased devotion to the literature of the past, which came partly from the felt loss of spontaneity and partly from national pride,[145] caused these compositions in the rhetorical schools to take a wider range.[146] They began on the one hand to be divorced from even a fictitious connection with the law-courts, and on the other to be directly imitative of the styles of ancient authors. From the older Rhetoric, the study of forensic logic and speech with a view to the actual practice in the law-courts, which necessarily still went on, there branched out the new Rhetoric, which was sometimes specially known as Sophistic. * * * * *
