larger than the arch of Titus. As a specimen of the triumphal arches, a drawing of the arch of Drusus is given in the preceding page. [Illustration: Arch of Drusus at Rome] ARCUS (βιός, τόξον), the bow used for shooting arrows, is one of the most ancient of all weapons, but is characteristic of Asia rather than of Europe. In the Roman armies it was scarcely ever employed except by auxiliaries; and these auxiliaries, called _sagittarii_, were chiefly Cretes and Arabians. The upper of the two figures below shows the Scythian or Parthian bow unstrung; the lower one represents the usual form of the Grecian bow, which had a double curvature, consisting of two circular portions united by the handle. When not used, the bow was put into a case (τοξοθήκη, γωρυτός, _corytus_), which was made of leather, and sometimes ornamented. It frequently held the arrows as well as the bow, and on this account is often confounded with the _pharetra_ or quiver. [Illustration: Arcus, Bow. (From paintings on vases.) Corytus, Bow-case. (From a Relief in the Vatican, Visconti, iv. tav. 43.)] ĀRĔA (ἅλως, or ἁλωά), the threshing-floor, was a raised place in the field, open on all sides to the wind. Great pains were taken to make this floor hard; it was sometimes paved with flint stones, but more usually covered with clay and smoothed with a roller. ĂREIOPĂGUS (ὁ Ἄρειος πάγος, or hill of Ares) was a rocky eminence, lying to the west of, and not far from the Acropolis at Athens. It was the place of meeting of the council (Ἡ ἐν Ἀρείῳ πάγῳ βουλή), which was sometimes called _The Upper Council_ (Ἡ ἄνω βουλή), to distinguish it from the senate of Five-hundred, which sat in the Cerameicus within the city. It was a body of very remote antiquity, acting as a criminal tribunal, and existed long before the time of Solon, but he so far modified its constitution and sphere of duty, that he may almost be called its founder. What that original constitution was, must in some degree be left to conjecture, though there is every reason to suppose that it was aristocratical, the members being taken, like the ephetae, from the noble patrician families. [EPHETAE.] By the legislation of Solon the Areiopagus was composed of the ex-archons, who, after an unexceptionable discharge of their duties, “went up” to the Areiopagus, and became members of it for life, unless expelled for misconduct. As Solon made the qualification for the office of archon to depend not on birth but on property, the council after his time ceased to be aristocratic in constitution; but, as we learn from Attic writers, continued so in spirit. In fact, Solon is said to have formed the two councils, the senate and the Areiopagus, to be a check upon the democracy; that, as he himself expressed it, “the state riding upon them as anchors might be less tossed by storms.” Nay, even after the archons were no longer elected by suffrage, but by lot, and the office was
