Pachomius established his first monastery between 318 and 323 at Tabennisi, Egypt. His elder brother John joined him, and soon more than 100 monks lived nearby. Pachomius set about organizing these cells into a formal organization. Until then, Christian asceticism had been solitary or "eremitic" with male or female monastics living in individual huts or caves and meeting only for occasional worship services. Pachomius created the community or "cenobitic" organization, in which male or female monastics lived together and held their property in common under the leadership of an abbot or abbess. Pachomius realized that some men, acquainted only with the eremitical life, might speedily become disgusted if the distracting cares of the cenobitical life were thrust too abruptly upon them. He therefore allowed them to devote their whole time to spiritual exercises, undertaking all the community's administrative tasks himself. The community hailed Pachomius as "Abba" ("father" in Hebrew), from which "Abbot" derives.
