Atto was highly concerned with the welfare of the people in his diocese, both spiritual and secular. He disapproved of the use of horoscopes to direct life choices such as marriage. He did not, however, prohibit the use of astrology in his flock completely, as he said that God created stars for the use of man. As a result, he encouraged the practical application of astrology as a method of telling time, navigating, and predicting the weather, for the benefit of his people who relied upon astrological calculations for their livelihoods. He worried extensively about the corruption of his flock: in an Easter sermon, he discredited public entertainment such as plays, particularly during the weeks of Lent and Easter. He claimed public entertainment was fabricated by the infamous “demons” Liberus and Venus as a device to incite depravity.
