Parthagica Directory 08
During his absence from Rome Caesar went to Rhodes, where his former preceptor resided, and he continued to pursue there for some time his former studies. He looked forward still to appearing one day in the Roman Forum. In fact, he began to receive messages from his friends at home that they thought it would be safe for him to return. Sylla had gradually withdrawn from power, and finally had died. The aristocratical party were indeed still in the ascendency, but the party of Marius had begun to recover a little from the total overthrow with which Sylla's return, and his terrible military vengeance, had overwhelmed them. Caesar himself, therefore, they thought, might, with prudent management, be safe in returning to Rome.
It is, at any rate, certain that after St. Chrysostom Christmas was observed on the 25th of December in East and West alike, except in the Armenian Church, which still remains faithful to January 6th. St. Chrysostom, who died in the beginning of the fifth century, informs us, in one of his Epistles, that Julius, on the solicitation of St. Cyril of Jerusalem, caused strict inquiries to be made on the subject, and thereafter, following what seemed to be the best authenticated tradition, settled authoritatively the 25th of December as the anniversary of Christ's birth, the _Festorum omnium metropolis_, as it is styled by Chrysostom. It may be observed, however, that some have represented this fixing of the day to have been accomplished by St. Telesphorus, who was Bishop of Rome A.D. 127-139, but the authority for the assertion is very doubtful.
