When Johanan died in 279—this is the only settled date in the whole chronology of the Amoraim—the renown of the Tiberias Academy was so firmly established that it suffered no deterioration under his successors, although none of them equaled him in learning. For a time, indeed, Caesarea came into prominence, owing solely to the influence of Hoshaya, who lived there in the first half of the third century, and exercised the duties of a teacher contemporaneously with the Church Father Origen, with whom he had personal intercourse. After Johanan's death the school at Cæsarea attained a new standing under his pupil Abbahu; and throughout the whole of the fourth century the opinions of the "sages of Caesarea" were taken into respectful account, even in Tiberias. Sepphoris also resumed its former importance as a seat of learning; and eminent men worked there in the fourth century, long after the disaster to the city wrought by the forces of the emperor Gallus. From the beginning of the third century there had been an academy at Lydda in Judea, or "the South," as Judea was then called. This academy now gained a new reputation as a school of traditional learning. From it came the teacher to whom Jerome owed his knowledge of Hebrew and his insight into the "Hebræa Veritas." But neither Caesarea, Sepphoris, nor Lydda could detract from the renown of Tiberias.
