Saint Basil the Great in his rules addresses both men and women. Augustine of Hippo drew up the first general rule for such communities of women. It was written in the year 423 and was addressed to Felicitas, Superioress of the Monastery of Hippo, and to Rusticus, the priest whom Augustine had appointed to have charge of the nuns. In Ireland, St. Patrick instituted canons regular, and St. Bridget was the first of numberless canonesses. The monasteries of the Gilbertine Order were nearly always double, for men and women.
