We can picture to ourselves how it must have startled the refined Græco-Egyptian world of Alexandria when occasionally some man, long lost to society and forgotten by his friends, reappeared in the streets and squares of the city, with attenuated limbs and mortified countenance, with a dark hair-cloth tunic for his only clothing, with a reputation for exalted sanctity and spiritual wisdom, and vague rumours of supernatural revelations of the unseen world; like another John Baptist sent to preach repentance to the luxurious citizens; or fetched, perhaps, by the Alexandrian bishop to give to the church the weight of his testimony to the ancient truth of some doctrine which began to be questioned in the schools. Such men, when they returned to the desert, were frequently accompanied by numbers of others, whom the fame of their sanctity and the persuasion of their preaching had induced to adopt the eremitical life. It is not to be wondered at that these new converts should frequently build, or select, their cells in the neighbourhood of that of the teacher whom they had followed into the desert, and should continue to look up to him as their spiritual guide. Gradually, this arrangement became systematised; a number of separate cells, grouped round a common oratory, contained a community of recluses who agreed to certain rules and to the guidance of a chosen head; an enclosure wall was generally built around this group, and the establishment was called a _laura_. The transition from this arrangement of a group of anchorites occupying the anchorages of a laura under a spiritual head, to that of a community living together in one building under the rule of an abbot, was natural and easy. The authorship of this coenobite system is attributed to St. Anthony, who occupied a ruined castle in the Nile desert, with a community of disciples, in the former half of the fourth century. The coenobitical institution did not supersede the eremitical; both continued to flourish together in every country of Christendom.[2] The first written code of laws for the regulation of the lives of these communities was drawn up by Pachomius, a disciple of Anthony's. Pachomius is said to have peopled the island of Tabenne, in the Nile, with coenobites, divided into monasteries, each of which had a superior, and a dean to every ten monks; Pachomius himself being the general director of the whole group of monasteries, which are said to have contained eleven hundred monks. The monks of St. Anthony are represented in ancient Greek pictures with a black or brown robe, and often with a tau cross of blue upon the shoulder or breast.
