The second opinion as to the authorship is found in no writer of any name. It occurs only in two places: a poem falsely ascribed to Tertullian, and a fragment published by Muratori, on the Canon, the authorship of which is unknown, and the original language of which is still a matter of dispute. The fragment says, “The Pastor was written very lately in our times, in the city of Rome, by Hermas, while Bishop Pius, his brother, sat in the chair of the Church of the city of Rome.”
