Moulton & Milligan — Vocabulary of the Greek NT
βάσις. The word is common in the inscriptions for the ‘base ἢ of a statue, e.g. OG/S 7058 (ii/A.p.) τὸν ἀνδριάντα σὺν τῆι βάσει ἀνέθηκε, A/agn 02}. 17 τὸ] δὲ ψήφισμα τόδε ἀναγραφῆναι εἰς τὴμ βάσιν τῆς εἰκόνος THs’ Α[πο]λλοφάνου, See also P Lond 755 verso® (iv/a.p.) (= III. p- 222) β]άσις kal κεφαλίδες, ““base mouldings and capitals” of pillars, P Grenf I. 141° (B.C. 150. or 139) βάσιν λυχνί(ου), Sy// 540193 (B.C, 175-1) ἐργᾶται (sc. a builder contracting for a temple) τῶν λίθων πάντων τὰς βάσεις ὀρθάς, ἀστραβεῖς, ἀρραγεῖς κτλ, 7/18! τῶν λίθων πάντων τοὺς ἁρμοὺς καί τ[ὰς βά]σεις, 588787 (c. B.C. 180) λαμπὰς χαλκῆ ἐπὶ βάσεως, etc. The medical use of B. = ‘‘ foot” in Ac 37 is illustrated by Hobart, Medical Language of St Luke, p. 34f. It may have this meaning in the great magical papyrus, P Lond 121518 (ili/A.D.) (=I. p. 101) παρέστω cor τοῖς δυσὶ βάσεσιν σκιαθι. Its geometrical meaning, as the ‘‘base” of a triangle, appears with fragmentary context in P Brit Mus 372° (ii/A.p.), printed in P Tebt IT. Ῥ- 339ff., a land survey.
