Moulton & Milligan — Vocabulary of the Greek NT
ἀΐδιος. Syil 306 (ii/B c.—Delphi) ὅπως ὑπάρχῃ ἁ δωρεὰ εἰς πάντα τὸν χρόνον ἀΐδιος. In OG/S 565: (iii/B.c., the Canopus inscription of Ptolemy III.) it is ordained to pay τιμὰς ἀϊδίους in all the temples to Queen Berenice, who els θεοὺς μετῆλθεν shortly before. So 26. 248° (ii/B.C., Antiochus Epiphanes) τὰ καλὰ τῶ[ν] ἔργων els ἀΐδιομ. μνήμην ἀνάγων. In 74. 3831 Antiochus I. of Commagene (i/s.c.) claims περὶ δὲ ἱερουργιῶν ἀϊδίων διάταξιν πρέπουσαν ἔποιησάμην. The phrase τ. ἀΐδιον χρόνον is common in the inscriptions, e.g. Sy// 968 (iv/B.c.). The adjective has been restored in the late P Lond 113® (vi/a.p.) (=I. p. 202) τὴν ἀϊδί[α]ν ἰσχύν : otherwise we cannot quote papyri— possibly the word was only appropriate to the stiffer language of inscriptions.
