ἴσος. In BGU II. 6465 (a.D. 193) ἵνα πάντες ἰδιῆτα[ι] (1. εἰδῆτε) καὶ ταῖς ἴσαις ‘Apfeats ἑορτάση[τα]ι (1. ἑορτάσητε) Wilcken (Chrest. Τ. p. 570) understands the reference to be not to the same eae days, but to the same length of time, viz. 15 days as stated later in the document. “equal cain? quality, cf. P Strass I. 32: (a. D. 261) ζυγὸν δὲ ἐνάγων παρά σοι τὸν ἐπιτηδειότερον αὐτῷ παράσχες, τὸν ἴσον σεαυτῷ ποιήσας εἰς τὰ παρά σοι ἔργα. The neut. is common 85 ἃ subst. = “ΠΟΡΥ,᾿ e.g. P Lond 1222 (A.D. 138) (=III. p. 126), a letter enclosing a copy of a rescript, and | requesting that another Eapy should be given to a certain woman—rd ἴσον δι ὑπηρέτου μεταδοθῆναι t[q] διά [σου δηλ[ουμέϊνῃ Θερμουθαρίωι, and similarly P Tebt II. 3015: (A.D. 190) ἔσχον τούτου [τὸ ἴ]σον ἄχρι ἐξετάσεως, “1 have received a copy of this [a notice of death] for investigation.” For τὰ ἴσα, as in Lk 65", cf. P Ryl IT. 657 (B.c. 67?) els τὸ βασιλικὸν τὰ toa, ‘the same sum to the Treasury,’’ and for ἴσα used adverbially (as in Phil 2°, cf. Job 117%, 301%), see the curious nursery alphabet P Tebt II. 278°% (early i/A.D.)— ἴσα otra ἦρκε, κάλλιστον ἱμάτιν, ‘just so he stole it, my lovely garment.” This usage survives in MGr Yo(t)o μέ (1.4. μετά), “till,’’ “up to” (Thumb Handb. p.111). Cf. also the adverbial phrase ἐξ ἴσου, as in P Fay 34" (A.D. 161) κατὰ μῆνα τὸ αἱροῦν ἐξ ἴσου, ‘in equal monthly instalments” (Edd.), 24. 9317 (a.D. 161), a/., and ἐπ᾽ ἴσηι kal ὁμοίηι, “upon equal and similar terms,” as in Syil 16227 (end of iv/B.c.).
