"The Greek word laura is employed by writers from the end of the fifth century to distinguish the monasteries of Palestine of the semi-eremitical type. The word signifies a narrow way or passage, and in later times the quarter of a town. We find it used in Alexandria for the different portions of the city grouped around the principal churches; and this latter sense of the word is in conformity with what we know of the Palestine laura, which was a group of hermitages surrounding a church.
Although the term laura has been almost exclusively used with regard to Palestine, the type of monastery which it designated existed, not only there, but in Syria and Mesopotamia; in Gaul; in Italy; and among the Celtic monks. The type of life led therein might be described as something midway between purely eremitical inaugurated by St. Paul the first hermit- and purely cenobitical life. The monk lived alone though depended on a superior, and was bound only to the common life on Saturdays and Sundays, when all met in church for the solemn Eucharistic Liturgy."
