ὁ περὶ τοῦ δοῦλον εἶναι π€ντα φαῦλον, ᾧ ἐξῆς ἐστιν ὁ περὶ τοῦ π€ντα σπουδαῖον ἐλεύθερον εἶναι. These two works formed originally the two halves of a single work, in which the subject was treated from its two sides,—the slavery of the wicked man and the freedom of the good man. The first half is lost; but the second half is extant, and is given by Mangey (II. 445–470). A long fragment of the extant second half is given also by Eusebius, in his Præp. Evang. VIII. 12. The genuineness of the work has been disputed by some, but is defended with success by Lucius, Der Essenismus, p. 13–23, Strasburg, 1881 (Schürer, p. 85).
