ἄχρηστος [page 99] P Tebt I. 74 .36, .70 , 75 .56 .36 (both ii/B.C.) of unproductive land. So in CPHerm 7 iii. 6 (ii/A.D.), but hiat contextus. It describes a pig in P Flor II. 127 .14 (A.D. 256) ἀλλὰ καλὸν πάλιν ἔστω , μὴ ὡς πρώην̣ καὶ λεπτὸν καὶ ἄχρηστον . Ib. 185 .7 (A.D. 254) κατεαγμένα καὶ ἄχρηστα , of panniers, and P Oxy X. 1346 (ii/A.D. ?) ἄχρηστος [γ ]έγωναι ( l. γέγονε ), of a garment. Cagnat IV. 293 .14 (Pergamon, B.C. 127 6) κατεφθαρμέ [νον . . . καὶ ] . . . γεγονὸς ἄχρησ̣[τον , of a gymnasium. The moral sense of the word comes out in P Oxy VII. 1070 .50 ff. (iii/A.D.) μὴ ἀμελήσῃς μὴ ἄρα ποτὲ θέλῃς μ̣[ε ]τὰ σ̣[ο ]ῦ [Ἡρ ]αε̣ι̣δ̣ι̣ τὴν τήρησιν τῆς ὅλης οἰκίας παραδιδόναι ἀχρήστου̣ οὔσης αὐτῆς , do not neglect this, lest indeed you choose to hand over the keeping of the whole house to Heraοs, who is unworthy (Ed.). The resemblance to Philem .11 is obvious. Vettius (p. 62 .7 ) speaks of ἄχρηστα βρέφη .
