Benedict of Nursia, who fulfilled much the same function in the West, took his Regula Benedicti from the writings of Basil and other earlier church fathers.
Basil visited Egypt, Coele-Syria, Mesopotamia, and Palestine in order to see for himself the manner of life led by the monks in these countries.
In the latter country and in Syria the monastic life tended to become more and more eremitical and to run to great extravagances in the matter of bodily austerities.
He sends his monks to the Sacred Scriptures; in his eyes the Bible is the basis of all monastic legislation, the true Rule.
It leaves to the superiors the care of settling the many details of local, individual, and daily life; it does not determine the material exercise of the observance or the administrative regulations of the monastery.
In 397, Rufinus who translated them into Latin united the two into a single Rule under the name of Regulae sancti Basilii episcopi Cappadociae ad monachos.
Basil's influence ensured the propagation of Basilian monachism; and Sozomen says that in Cappadocia and the neighboring provinces there were no hermits but only cenobites.
[1] The monks, as a rule, followed the theological vicissitudes of the emperors and patriarchs, and they showed no notable independence except during the iconoclastic persecution; the stand they took in this aroused the anger of the imperial controversialists.
It acquired its fame in the time of the iconoclastic persecution while it was under the government of the saintly hegoumenos (abbot) Theodore, called the Studite.
But to effect this, and to give permanence to the reformation, he saw that there was need of a more practical code of laws to regulate the details of the daily life, as a supplement to St Basil's Rules.
[2] The monastery was an active center of intellectual and artistic life and a model which exercised considerable influence on monastic observances in the East.
Theodore attributed the observances followed by his monks to his uncle, the saintly Abbot Plato, who first introduced them in his monastery of Sakkoudion.
In 885, a decree of Emperor Basil I proclaimed Mount Athos a place of monks, and no laymen or farmers or cattle-breeders are allowed to be settled there.
The Monastery of St. Catherine on Mount Sinai, built in 548, goes back to the early days of monasticism, and is still occupied by monks.
These monasteries, and others as well, were studios of religious art where the monks toiled to produce miniatures in the manuscripts, paintings, and goldsmith work.
Among the authors of hymns may be mentioned: Romanus the Melodist;[9] Andrew of Crete; Cosmas of Jerusalem, and Joseph the Hymnographer.
Owing to this the monks formed a class apart, corresponding to the upper clergy of the Western Churches; this gave and still gives a preponderating influence to the monasteries themselves.
[10] The Oratory of Saint Mark in Rossano, was founded by Nilus, as a place of retirement for nearby eremite monks.
Cardinal Bessarion, who was Abbot of Grottaferrata, sought to stimulate the intellectual life of the Basilians by means of the literary treasures which their libraries contained.
