Moulton & Milligan — Vocabulary of the Greek NT
ἀστήρικτος ““Nestorius, presbyter, lies here, who shone a star among the Churches of God.’’ One might suspect the ultimate origin of the phrase in Plato’s exquisite epitaph on his friend Aster— ᾿Αστὴρ πρὶν μὲν Rapes ἔνι ζωοῖσιν ἑῷος, νῦν δὲ θανὼν λάμπεις ἕσπερος ἐν φθιμένοις. Other instances οἵ ἀστήρ are P Petr ITI. 1345 (anastronomical fragment relating to the 36 decans presiding over the ten days’ periods), P Par 1 (Eudoxus treatise, ii/B.c.) in the Opening acrostic 2° χρόνος διοικῶν ἀστέρων γνωρίσματα, P Leid Wii τῶν ζ ἀστέρων (magic), 7. V χει, 5 ἀστὴρ ἀπὸ κεφαλῆς, etc. But we cannot quote it from papyri outside those on astrological or astronomical subjects and magic. It survives, however, in MGr ἀστέρας. oy) ἀστήριτος. Mayor (on 2 Pet 214) cites Longinus ii. 2, ἀστήρικτα καὶ ἀνερμάτιστα ‘‘unstable and unballasted (Roberts): this should be added to Grimm’s Anthology citation. We do not trouble much about vernacular warrant for words in 2 Pet. It occurs six times in Vettius Valens, in the phrase a. λογισμοῦ ‘unstable in judgement.
