 Another compilation of this kind, entitled "Περὶ τῆς ἐξ ἀρχῆς καὶ μέχρι τέλους οἰκονομίας τοῦ θεοῦ, εἰς τὸν ἄνθρωπον ἱστορία ἐπωφελής· καὶ περὶ τῆς χριστιανικῆς πολιτείας, ὅπως συνέστη· καὶ κατὰ πάντων τῶν αἱρετικῶν" or simply "De Oeconomia Dei" covering the whole province of theology in five separate books, is ascribed to the twelfth-century monk Nilus Doxopatres, related to but certainly not identical with the eleventh-century John Doxopatres; the first two books, treating respectively of Adam and Christ, are all that remain.A number of other dogmatic florilegia are still extant in manuscript form.The authors of most of them are unknown.
