(Subst.adj.adj.) : Argŏs, n. (only nom. and acc.), more freq. in the plur. Argi, ōrum, m. (Varr. L. L. 9, § 89 Müll.: Graecanice hoc Argos, cum Latine Argei; cf. Prob. p. 1447 P.; Phocae Ars, p. 1707 P.), = Ἄργος.
* Argos, the capital of Argolis, in the Peloponnesus, sacred to Juno, also called Argos Hippium and Argos Dipsium or Inachium, Plin. 4, 5, 9; 7, 56, 57; cf. Mann. Gr. p. 641 sq.: quaerit Argos Amymonen,Ov. M. 2, 240; so id. ib. 6, 414; Hor. C. 1, 7, 9: securum per Argos,Ov. H. 14, 34; so Luc. 10, 60: patriis ab Argis Pellor,Ov. M. 14, 476; 15, 164; Verg. A. 7, 286; Hor. S. 2, 3, 132; id. Ep. 2, 2, 128; id. A. P. 118; Liv. 34, 25 et saep.—The acc. Argos, occurring in the histt., is best considered as plur., since the sing. seems rather to belong to the poets and geographers (e. g. Plin. above cited); cf. Daehne and Bremi ad Nep. Them. 8, 1.
* Poet., Argos is sometimes put for the whole of Greece, Luc. 10, 60.—Hence
* Derivv., the adjj.
* Argīvus, a, um (i. e. ArgiFus from ArgeiFos, like Achivus from Ἀχαιός), of Argos, Argive, Plaut. Am. 1, 1, 53: Argivus orator,Cic. Brut. 13, 50: augur,i.e. Amphiaraus,Hor. C. 3, 16, 12 —An epithet of Juno (as in the Iliad Ἀργεία is an appel. of Here) as tutelary goddess of Argos, Verg. A. 3, 547.
* Poet. for Greek or Grecian in gen.: castra,Verg. A. 11, 243: phalanx,id. ib. 2, 254: ensis,id. ib. 2, 393: Thalia,Hor. C. 4, 6, 25 (cf. id. ib. 2, 16, 38: Graja Camena).—And so Argivi for the Greeks: classis Argivūm,Verg. A. 1, 40; 5, 672; Hor. C. 3, 3, 67; Val. Max. 5, 1, ext. 4.
* Without digamma, Argēus (Argī-), a, um, Argive or Grecian: Argia sacerdos,Cic. Tusc. 1, 47, 113 (B. and K., Argiva): Tibur Argeo positum colono (cf. Serv. ad Verg. A. 7, 670), Hor. C. 2, 6, 5 K. and H.; so, Tibur Argeum,Ov. Am. 3, 6, 46 Merk.
* Argŏlis, ĭdis, f., = Ἀργολίς.
* Argive: Alcmene,Ov. M. 9, 276: puppis,id. R. Am. 735.
* Argus, a, um, adj., Argive: Argus pro Argivus, Plaut. Am. (prol. 98): Amphitruo natus Argis ex Argo patre,Non. p. 487, 31. (So the much-contested passage seems to be better explained than when, with Gronov. Observv. 4, 298, Argo is considered as abl. from Argos, begotten of a father from Argos, to which Argis in the plur. does not correspond.)
