Hermas, author of The Shepherd of Hermas, was the brother of Pope Pius I (as the Liberian Catalogue, the poem against Marcion, and the Muratorian fragment all state). Theodor Zahn has shown that the work of Hegesippus may still have been extant in the sixteenth and seventeenth centuries in three Eastern libraries, saying: "We must lament the loss of other portions of the Memoirs which were known to exist in the seventeenth century."
