This work, which is not extant (although its title appears in one of the oldest mss. of Tertullian, the Codex Agobardinus), is mentioned by St. Jerome in his Commentary on Ezekiel, chap. xxxvi.; in the preface to his Comment. on Isaiah, chap. xviii.; and in his notice of Papias of Hierapolis (Oehler).
