ὀρθός [page 456] ὀρθός is used of standing hay in P Lond 1165 .2 (ii/A.D.) (= III. p. 191) [χόρτ ] ᵒ χλωροῦ ὀρθοῦ : cf. ib. 755 verso .2 (iv/A.D.) (= III. p. 221) where standing columns (ἑστῶτες corrected from ὀρθοί ) are contrasted with those that have fallen (χαμαὶ κείμενοι ). In Syll 540 .18 (B.C. 175 1) ποιῶν ὀρθὰ πάντα πρὸς κανόνα διηνεκῆ , we have the meaning straight. The metaphorical use of the adj. is seen in PSI V. 549 .8 (B.C. 42 1) ὀρθὴ στήσομαι ἀπέναντί σου , with reference to the attitude of a servant to her mistress, and BGU I. 248 .9 (i/A.D. : see ib. II. 594 note) διὰ γὰρ τὴν [σ ]ὴ [ν ] πρόν [ο ]ια [ν ] ἐν ὀρθῶι μέλλει γείνεσθαι ( l. γίνεσθαι ) : cf. P Oxy III. 490 .16 (A.D. 124) καὶ ἔστιν μου ἡ σφραγὶς Ἁρποχράτου ὀρθοῦ , the signature of a witness, Kaibel 397 .1 μαρτύριον ὀρθοῦ βίου , and OGIS 329 .10 (mid. ii/B.C.) ἀπ᾽ ὀρθῆς , from the right (way) : Heb_12:13 . MGr ὀρθός (ὀρτός in Eastern dialects : Thumb Handbook p. 18), straight, correct ; steep. The last meaning recalls the cognate Lat. arduus : ὀρθός , however, had originally an initial, and probably also a medial, digamma ( * Ϝορθός , * Ϝορθ Ϝός ) (Boisacq, p. 711).
