The Ecclesiastical History of Sozomen

It is said that God frequently in many other cases revealed to the princess what was about to happen, and that the most occurred to her and her sisters as witnesses of the Divine love. They all pursue the same mode of life; they are sedulous about the priests and the houses of prayer, and are munificent to needy strangers and the poor. These sisters generally take their meals and walks together, and pass their days and their nights in company, singing the praises of God. As is the custom with exemplary women, they employ themselves in weaving and in similar occupations. Although princesses, born and educated in palaces, they avoid levity and idleness, which they think unworthy of any who profess virginity, so they put such indolence far from their own life. For this reason the mercy of God is manifested and is conquering in behalf of their house; for He increases the emperor in years and government; every conspiracy and war concocted against him has been overthrown of itself.
