Athanasius the' Apostolic entrusted Didymus the Blind to head the school , from about 315 to 398 . He lived during the tempestuous age of Arianism and the Council of Nicea . Amongst his pupils were St . Gregory Nazianzus , St . Jerome and the historian Rufinus . It is interesting to know that he cared for the welfare of the blindd , as he had been blind from the age of four - by promoting a system of embossed or engraved writing for them , for the first time' in history .

Then the zeal and the knowledge began to fade , and within them a great institution .
