81 Cierva, Juan de la
SUBJECT AREA: Aerospace[br]b. 21 September 1895 Murcia, Spaind. 9 December 1936 Croydon, England[br]Spanish engineer who played a major part in developing the autogiro in the 1920s and 1930s.[br]At the age of 17, Cierva and some of his friends built a successful two-seater biplane, the BCD-1 (C for Cierva). By 1919 he had designed a large three-engined biplane bomber, the C 3, which unfortunately crashed when its wing stalled (list its lift) during a slow-speed turn. Cierva turned all his energies to designing a flying machine which could not stall: his answer was the autogiro. Although an autogiro looks like a helicopter, its rotor blades are not driven by an engine, but free-wheel like a windmill. Forward speed is provided by a conventional engine and propeller, and even if this engine fails, the autogiro's rotors continue to free-wheel and it descends safely. Cierva patented his autogiro design in 1920, but it took him three years to put theory into practice. By 1925, after further improvements, he had produced a practical rotary-winged flying machine.He moved to England and in 1926 established the Cierva Autogiro Company Ltd. The Air Ministry showed great interest and a year later the British company Avro was commissioned to manufacture the C 6A Autogiro under licence. Probably the most significant of Cierva's autogiros was the C 30A, or Avro Rota, which served in the Royal Air Force from 1935 until 1945. Several other manufacturers in France, Germany, Japan and the USA built Cierva autogiros under licence, but only in small numbers and they never really rivalled fixed-wing aircraft. The death of Cierva in an airliner crash in 1936, together with the emergence of successful helicopters, all but extinguished interest in the autogiro.[br]Principal Honours and DistinctionsDaniel Guggenheim Medal. Royal Aeronautical Society Silver Medal, Gold Medal (posthumously) 1937.Bibliography1931, Wings of To-morrow: The Story of the Autogiro, New York (an early account of his work).He read a paper on his latest achievements at the Royal Aeronautical Society on 15 March 1935.Further ReadingP.W.Brooks, 1988, Cierva Autogiros: The Development of Rotary Wing Flight, Washington, DC (contains a full account of Cierva's work).Jose Warleta. 1977, Autogiro: Juan de la Cierva y su obra, Madrid (a detailed account of his work in Spain).Oliver Stewart, 1966, Aviation: The Creative Ideas, London (contains a chapter on Cierva).JDS -

86 πρῶτος
πρῶτος, η, ον (Hom.+; loanw. in rabb.).① pert. to being first in a sequence, inclusive of time, set (number), or space, first of several, but also when only two persons or things are involved (=πρότερος; exx. in Hdb. on J 1:15; Rdm.2 71f; Thackeray 183; s. also Mlt. 79; 245; B-D-F §62; Rob. 516; 662; and s. Mt 21:31 v.l.).ⓐ of time first, earliest, earlierα. as adj. ἀπὸ τῆς πρώτης ἡμέρας ἄχρι τοῦ νῦν Phil 1:5; cp. Ac 20:18 (on the absence of the art. [also Phil 1:5 v.l.] s. B-D-F §256; Rob. 793). ἡ πρώτη ἀπολογία 2 Ti 4:16 (MMeinertz, Worauf bezieht sich die πρώτη ἀπολογία 2 Ti 4:16?: Biblica 4, 1923, 390–94). ἡ πρ. διαθήκη Hb 9:15. τὰ πρῶτα ἔργα Rv 2:5. ἡ ἀνάστασις ἡ πρώτη 20:5f. ἡ πρώτη ὅρασις Hv 3, 10, 3; 3, 11, 2; 4. ἡ ἐκκλησία ἡ πρ. 2 Cl 14:1.—Subst. τὰ πρ. … τὰ ἔσχατα (Job 8:7): γίνεται τὰ ἔσχατα χείρονα τῶν πρώτων Mt 12:45; cp. Lk 11:26; 2 Pt 2:20; Hv 1, 4, 2. οἱ πρῶτοι (those who came earlier, as Artem. 2, 9 p. 93, 19 those who appeared earlier) Mt 20:10; cp. vs. 8. ἀπέστειλεν ἄλλους δούλους πλείονας τῶν πρώτων 21:36. Cp. 27:64. πρῶτος ἐξ ἀναστάσεως νεκρῶν the first to rise from the dead Ac 26:23. ὁ πρῶτος the first one J 5:4; 1 Cor 14:30. On the self-designation of the Risen Lord ὁ πρ. καὶ ὁ ἔσχατος Rv 1:17; 2:8; 22:13; s. ἔσχατος 2b (πρ. of God: Is 44:6; 48:12).—As a predicate adj., where an adv. can be used in English (ParJer 1:8 εἰ μὴ ἐγὼ πρῶτος ἀνοίξω τὰς πύλας; B-D-F §243; Rob. 657), as the first one = first ἦλθεν πρῶτος he was the first one to come = he came first J 20:4; cp. vs. 8. πρῶτος Μωϋσῆς λέγει Ro 10:19. Ἀβραὰμ πρῶτος περιτομὴν δούς Abraham was the first to practice circumcision B 9:7. οἱ ἄγγελοι οἱ πρῶτοι κτισθέντες the angels who were created first Hv 3, 4, 1; Hs 5, 5, 3.—1 Ti 2:13; 1J 4:19; AcPlCor 2:9.—ἐν ἐμοὶ πρώτῳ in me as the first 1 Ti 1:16.—Used w. a gen. of comparison (Ocelus Luc. 3 ἐκεῖνο πρῶτον τοῦ παντός ἐστιν=prior to the All; Manetho 1, 329; Athen. 14, 28 p. 630c codd.) πρῶτός μου ἦν he was earlier than I = before me J 1:15, 30 (PGM 13, 543 σοῦ πρῶτός εἰμι.—Also Ep. 12 of Apollonius of Tyana: Philostrat. I p. 348, 30 τὸ τῇ τάξει δεύτερον οὐδέποτε τῇ φύσει πρῶτον). So perh. also ἐμὲ πρῶτον ὑμῶν μεμίσηκεν 15:18 (s. β below) and πάντων πρώτη ἐκτίσθη Hv 2, 4, 1.—As a rule the later element is of the same general nature as the one that precedes it. But it can also be someth. quite different, even its exact opposite: τὴν πρώτην πίστιν ἠθέτησαν 1 Ti 5:12. τὴν ἀγάπην σου τὴν πρώτην ἀφῆκες Rv 2:4.—Used elliptically ἡ πρώτη (i.e. ἡμέρα sim. Polyb. 5, 19, 1; 18, 27, 2 τῇ πρώτῃ) τῶν ἀζύμων Mt 26:17. πρώτῃ σαββάτου on the first day of the week Mk 16:9. In some of the passages mentioned above the idea of sequence could be predom.β. the neuter πρῶτον as adv., of time first, in the first place, before, earlier, to begin with (Peripl. Eryth. 4; Chariton 8, 2, 4; ApcEsdr 3:11; Just., D. 2, 4) πρῶτον πάντων first of all Hv 5:5a. ἐπίτρεψόν μοι πρῶτον ἀπελθεῖν καὶ θάψαι let me first go and bury Mt 8:21. συλλέξατε πρῶτον τὰ ζιζάνια gather the weeds first 13:30. Cp. 17:10, 11 v.l.; Mk 7:27; 9:11f; 13:10; Lk 9:59, 61; 12:1 ( first Jesus speaks to his disciples, and only then [vs. 15] to the people. If one prefers to take πρ. w. what follows, as is poss., it has mng. 2a); 14:28, 31; J 7:51; 18:13; Ac 26:20; Ro 15:24 al. in NT; B 15:7; Hv 3, 1, 8; 3, 6, 7; 3, 8, 11; 5:5b. τότε πρῶτον then for the first time Ac 11:26 D. πρῶτον … καὶ τότε first … and then (Sir 11:7; Jos., Ant. 13, 187) Mt 5:24; 7:5; 12:29; Mk 3:27; Lk 6:42; IEph 7:2. τότε is correlative w. πρῶτον without καί J 2:10 v.l. Likew. πρῶτον … εἶτα (εἶτεν) first … then (Just., D. 33, 2 al.; s. εἶτα 1) Mk 4:28; 1 Ti 3:10; B 6:17. πρῶτον … ἔπειτα (ἔπειτα 2) 1 Cor 15:46; 1 Th 4:16. πρῶτον … μετὰ ταῦτα Mk 16:9, s. vs. 12. πρῶτον … εἶτα … μετὰ ταῦτα 1 Cl 23:4; 2 Cl 11:3 (in both cases the same prophetic saying of unknown origin). πρῶτον … ἐν τῷ δευτέρῳ Ac 7:12.—Pleonastically πρῶτον πρὸ τοῦ ἀρίστου Lk 11:38.—W. gen. (Chariton 5, 4, 9 cod. πρῶτον τ. λόγων=before it comes to words) ἐμὲ πρῶτον ὑμῶν μεμίσηκεν it hated me before ( it hated) you J 15:18 (but s. 1aα).—W. the art. τὸ πρῶτον (Hom. et al.; Jos., Ant. 8, 402; 14, 205) the first time J 10:40; 19:39; at first (Diod S 1, 85, 2; Jos., Ant. 2, 340) 12:16; 2 Cl 9:5. τὰ πρῶτα (Hom. et al.; Appian, Syr. 15 §64; Ps.-Phoc. 8) the first time, at first MPol 8:2.ⓑ of number or sequence (the area within which this sense is valid cannot be marked off w. certainty from the area 1aα)α. as adj. Mt 21:28; 22:25; Mk 12:20; Lk 14:18; 16:5; 19:16; 20:29; J 19:32; Ac 12:10; 13:33 v.l.; Rv 4:7; 8:7; 21:19; Hs 9, 1, 5. τὸ πρῶτον … τὸ δεύτερον (Alex. Aphr., An. p. 28, 9 Br.) Hb 10:9. On πρώτης τῆς μερίδος Μακεδονίας πόλις Ac 16:12 s. μερίς 1 and RAscough, NTS 44, ’98, 93–103.—Since πρῶτος can stand for πρότερος (s. 1 at beg.; also Mlt-Turner 32), it by no means follows from τὸν μὲν πρῶτον λόγον Ac 1:1 that the writer of Luke and of Ac must have planned to write a third book (Zahn, NKZ 28, 1917, 373ff, Comm. 1919, 16ff holds that he planned to write a third volume; against this view s. EGoodspeed, Introd. to the NT ’37, 189; Haenchen, et al.—Athenaeus 15, 701c mentions the first of Clearchus’ two books on proverbs with the words ἐν τῷ προτέρῳ περὶ παροιμιῶν, but 10, 457c with ἐν τῷ πρώτῳ περὶ παροιμιῶν. Diod S 1, 42, 1 the first half of a two-part work is called ἡ πρώτη βίβλος and 3, 1, 1 mentions a division into πρώτη and δευτέρα βίβ. In 13, 103, 3 the designation for the first of two works varies between ἡ πρώτη σύνταξις and ἡ προτέρα ς. See Haenchen on Ac 1:1).—πρῶτος is also used without any thought that the series must continue: τὸν πρῶτον ἰχθύν the very first fish Mt 17:27. αὕτη ἀπογραφὴ πρώτη ἐγένετο Lk 2:2, likewise, does not look forward in the direction of additional censuses, but back to a time when there were none at all (Ael. Aristid. 13 p. 227 D. παράκλησις αὕτη [=challenge to a sea-fight] πρώτη ἐγένετο; for interpolation theory s. JWinandy, RB 104, ’97, 372–77; cp. BPearson, CBQ, ’99, 262--82).—τὰ τείχη τὰ πρῶτα Hs 8, 6, 6 does not contrast the ‘first walls’ w. other walls; rather it distinguishes the only walls in the picture (Hs 8, 7, 3; 8, 8, 3) as one edifice, from the tower as the other edifice.β. adv., the neuter πρῶτον of sequence in enumerations (not always clearly distinguished fr. sense 1aβ) first πρῶτον ἀποστόλους, δεύτερον προφήτας, τρίτον … 1 Cor 12:28 (Mitt-Wilck. I/2, 20 II, 10ff [II A.D.] τὸ πρ. … τὸ δεύτερον … τὸ τρίτον. Without the art. 480, 12ff [II A.D.]; Diod S 36, 7, 3; Tat. 40, 1). See Hb 7:2; Js 3:17.—Not infrequently Paul begins w. πρῶτον μέν without continuing the series, at least in form (B-D-F §447, 4; Rob. 1152. For πρ. without continuation s. Plat., Ep. 7, 337b, Plut., Mor. 87b; Jos., Ant. 1, 182; Ath. 27, 1 πρῶτα μέν) Ro 1:8; 3:2; 1 Cor 11:18. S. also 2 Cl 3:1.ⓒ of space outer, anterior σκηνὴ ἡ πρώτη the outer tent, i.e. the holy place Hb 9:2; cp. vss. 6, 8.② pert. to prominence, first, foremost, most important, most prominentⓐ adj.α. of things (Ocellus [II B.C.] 56 Harder [1926] πρώτη κ. μεγίστη φυλακή; Ael. Aristid. 23, 43 K.=42 p. 783 D.: πόλεις; Ezk 27:22; PsSol 17:43; χρυσίον τὸ πρῶτον τίμιον; JosAs 15:10) ἡ μεγάλη καὶ πρώτη ἐντολή Mt 22:38; cp.

Without superl. force ἐντολὴ πρώτη ἐν ἐπαγγελίᾳ a commandment of great importance, with a promise attached Eph 6:2 (the usual transl. ‘first commandment w. a promise’ [NRSV, REB et al.] loses sight of the fact that Ex 20:4–6=Dt 5:8–10 has an implied promise of the same kind as the one in Ex 20:12=Dt 5:16. πρ. here is best taken in the same sense as in Mk 12:29 above). στολὴν τὴν πρώτην the special robe Lk 15:22 (JosAs 15:10).—ἐν πρώτοις among the first = most important things, i.e. as of first importance 1 Cor 15:3 (Pla., Pol. 522c ὸ̔ καὶ παντὶ ἐν πρώτοις ἀνάγκη μανθάνειν; Epict., Ench. 20; Mitt-Wilck I/2, 14 II, 9 ἐν πρώτοις ἐρωτῶ σε; Josh 9:2d).β. of persons (Dio Chrys. 19 [36], 35 πρ. καὶ μέγιστος θεός; TestAbr B 4 p. 108, 18 [Stone p. 64]; ApcSed 5:2; Jos., Ant. 15, 398; Just., A I, 60, 5 al. τὸν πρῶτον θεόν) ὸ̔ς ἂν θέλῃ ἐν ὑμῖν εἶναι πρῶτος whoever wishes to be the first among you Mt 20:27; Mk 10:44; cp. 9:35. πρῶτος Σίμων Mt 10:2 is not meant to indicate the position of Simon in the list, since no other numbers follow, but to single him out as the most prominent of the twelve.
