Germanus is thought by some authorities to have introduced the Gallican liturgy into Britain; he certainly established schools of learning, colleges and monasteries, where study was the principal work accomplished. During the Roman occupation of the country, there were no doubt professors of Greek and Latin in all the chief cities, possibly at London, York, and Caerleon; for it is not probable that the edict of Gratian, which required all the chief cities of the Empire to maintain such professorships, should not have been in force in Britain. But after the withdrawal of the Roman legions, it became difficult to keep up these professorships; and hence the foundation of monasteries, as schools of learning for the training of youths for the service of the Church, was suggested by Germanus; and to this end he consecrated Dubricius archbishop of Llandaff, and Daniel bishop of Bangor, besides appointing Iltutus to a place which took his name--Llan Iltut. The former founded colleges at Hentland-on-the-Wye (where he had a thousand pupils), and Llancarfan, or Llanfeithin, Caerworgorn, and Caerleon. The word _bangor_ in Welsh is simply a name for any college; and towards the end of the 5th century all Christian societies began to assume that epithet, _ban_, high; _côr_, circle or congregation. The word is written variously (in MSS.), "Ban Cor," "Banchor,"and "Bangor." Bangor Garmon, or the College of Germanus, at Llanveiltrin, in Glamorgan, was founded by him in 460. The congregation instituted by the Emperor Theodosius in Caer Worgorn having been destroyed by the Irish in the middle of the 5th century, was restored by Germanus, who placed Iltutus over it. This is now called in Welsh, "Llanilltyd Vawr," in Glamorganshire. According to the Triads, it contained no less than two thousand four hundred members, one hundred being employed every hour in order that the praise and service of God might be continued day and night without intermission. Gildas, the historian, and Talhaiarn, the bard, are said to have been educated there; and S. Cadvan and S. Padarn, the companions of S. Germanus, were among the members of the college until their appointment to similar work elsewhere. The College of S. Cadoc was also founded under the direction of Germanus and Catog, who preferred a life of study and religion to succession to his father's principality.
