ἀποστασία [page 68]
The noun ἀποστάτης (cf. LXX Dan 3 .32 ) occurs in P Revill Mιl (B.C. 130) (= Witkowski, .2 p. 96) χρήσασθαι δ᾽ αὐτοῖς ὡς ἀποστάταις ( sc. τοῖς ἐν Ἑρμώνθει ὄχλοις ), whom a certain Paon μετὰ δυνατῶν ἱκανῶν is sailing up the Nile to reduce (καταστῆσαι ). So in Syll 930 .50 (B.C. 112) τινες τῶν ἐγ Βοιωτίας ἀποστά [ται ] γεγενημένοι . In P Amh II.30 .33 ff (ii/B.C.) we read of the burning of title-deeds by Egyptian rebels, ἠναγκάσθην ὑπὸ τῶν Αἰγυπτίων ἀποστατῶν ἐνέγκαι τὰς συνγραφὰς καὶ ταύτας κατακαῦσαι . The old word ἀπόστασις , equivalent to σία (cf. 1Ma_2:15 , Act_21:21 , and see Nδgeli, p. 31), occurs in P Par 36 .13 (ii/B.C.), where a temple recluse petitions the strategus against the conduct of certain persons who had forced their way into the temple, βουλόμενοι ἐξσπάσαι με καὶ ἀγαγῆσαι , καθάπερ καὶ ἐν τοῖς πρότερον χρόνοις ἐπεχείρησαν , οὔσης ἀποστάσεως . For the adj. ἀποστατικός , see P Tor 8 .68 (B.C. 119) ἀποστατικῶι τρόπωι . In the same line αὐτοκρασίαι occurs, an illustration of the Hellenistic tendency to form new nouns in σία : see Lobeck, Parerga , p. 528 f.
