METHODIUS (†330), in his "Song of the Virgins" (II. 2). Ἄνωθεν, παρθένοι βοῆς, includes Judith and Susanna:
ὁρῶντες εἶδος εὐπρεπὲς, ὑφ᾽ ἧς
δύο κριταὶ Σουσάννας ἐμμανεῖς,
ἔρωτι λέξαν, Ὠ γύναι, κ.τ.λ.(Migne, Patr. gr. XVIII. 212).
HILARY OF POITIERS (†367), de Trin. IV. 8 (Migne, Patr. lat. 10, 101), quotes Susanna 42, "Sicut beata Sus. dicit, Deus æternus absconditorum cognitor, sciens omnia," etc.
ATHANASIUS (†373) also, in his Disc, against Arians, I. 13, quotes this popular verse (42) as "in Daniel." In the Life of Anthony, § 43, he refers to Susanna, as well as in the 'doubtful' Synopsis S.S.
EPHREM SYRUS (†378) refers both in his Ep. ad Johann. monachum, and in his 15th Parænesis, to the blessed Susanna.
GRATIAN (†383) notes on Can. XI. of Neocæsarea (315 A.D.) in Decreta I. 78, c. iv., "Daniel, we read, received the spirit of prophecy before he had arrived even at youth." The Canon itself, as given by Hefele, makes no mention of Daniel.
CYRIL OF JERUSALEM (†386) refers (Catech. I. 31) to Daniel's inspiration to rescue Susanna, and quotes v. 45 with γέγραπται γάρ.
GREGORY OF NYSSA (†396) quotes, in his Hexaëmeron (Migne, Patr. gr. XLIV. p. 71) and in his Making of Man, v. 42, twice as a prophetic writing (XXIX. 1).
AMBROSE (†397) has, Sermons XLIX. and L., "de accusato Domino apud Pilatum et de Susanna," in which he draws a parallel between them, as to silence under false charges, at considerable length (Basel, ed. 1527, III. 549).
SULPICIUS SEVERUS (†400?), in his Hist. Sacr. lib. II. § 1, gives an outline of the story of Susanna, after the events of Dan. i. and before those of chap, ii., evidently regarding it as historical.
