εἴκοσι [page 183]
εἴκοσι , and not εἴκοσιν , is the regular form in the papyri even before a vowel, as in the best MSS. of Act_1:15 , e.g. BGU II. 644 .19 (A.D. 69) εἴκοσι ἤ , ib. I. 267 .11 (A.D. 199) εἴκοσι ἀριθμῷ , P Grenf II. 59 .11 (A.D. 189) εἴκοσι ἀπό . Crφnert Mem.Herc. p. 141 n. .2 notes only one exception, P Grenf II. 75 .7 (A.D. 305) τάλαντα εἴκοσιν , ἃ πλήρωσέν ( l. ἐπλήρωσέν ) μοι : see also Mayser Gr. p. 239.
In Preisigke 1931 (ostracon A.D. 69) the word is written ἴκοσι : so 1932. For ἡ εἰκοστή as a tax of 5 per cent. on the rent of an οἰκόπεδον cf. P Petr II. 11 (2) .4 (mid. iii/B.C.) (= III. p. 112) ἀπογέγραμμαι δὲ ἐπὶ τελώνιον τὸ οἰκόπεδον φέρον ἐν [οίκιο ]ν (δραχμῶν ) ῑζ̄ (ἡμισείας ), ἵνα ἐκ τοσούτου φέρωμεν τὴν εἰκοστήν : see further Wilcken Ostr i. p. 363 f., and for a similar succession duty see Hunt in P Oxy VIII. p. 192.
