ARX signifies a height within the walls of a city, upon which a citadel was built, and thus came to be applied to the citadel itself. Thus one of the summits of the Capitoline hill at Rome is called Arx. The Arx was the regular place at Rome for taking the auspices, and was hence likewise called auguraculum; or, more probably, the auguraculum was a place in the Arx.
AS, or Libra, a pound, the unit of weight among the Romans. [[Libra].]
AS, the unit of value in the Roman and old Italian coinages, was made of copper, or of the mixed metal called [Aes]. It was originally of the weight of a pound of twelve ounces, whence it was called as libralis and aes grave. The oldest form of the as is that which bears the figure of an animal (a bull, ram, boar, or sow). The next and most common form is that which has the two-faced head of Janus on one side, and the prow of a ship on the other (whence the expression used by Roman boys in tossing up, Capita aut navim.) Pliny informs us, that in the time of the first Punic war (B.C. 264-241), in order to meet the expenses of the state, this weight of a pound was diminished, and asses were struck of the same weight as the sextans (that is, two ounces, or one-sixth of the ancient weight); and that thus the republic paid off its debts, gaining five parts in six; that afterwards, in the second Punic war, in the dictatorship of Q. Fabius Maximus (B.C. 217), asses of one ounce were made, and the denarius was decreed to be equal to sixteen asses, the republic thus gaining one half; but that in military pay the denarius was always given for ten asses; and that soon after, by the Papirian law (about B.C. 191), asses of half an ounce were made. The value of the as, of course, varied with its weight. Before the reduction to two ounces, ten asses were equal to the denarius = about 8½ pence English [[Denarius]]. Therefore the as = 3·4 farthings. By the reduction the denarius was made equal to sixteen asses; therefore the as = 2⅛ farthings. The as was divided into parts, which were named according to the number of ounces they contained. They were the deunx, dextans, dodrans, bes, septunx, semis, quincunx, triens, quadrans or teruncius, sextans, sescunx or sescuncia, and uncia, consisting respectively of 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1½, and 1 ounces. Of these divisions the following were represented by coins; namely, the semis, quincunx, triens, quadrans, sextans, and uncia. After the reduction in the weight of the as, coins were struck of the value of 2, 3, 4, and even 10 asses, which were called respectively dussis or dupondius, tressis, quadrussis, and decussis. Other multiples of the as were denoted by words of similar formation, up to centussis, 100 asses; but most of them do not exist as coins. In certain forms of expression, in which aes is used for money without specifying the denomination, we must understand the as. Thus deni aeris, mille aeris, decies aeris, mean respectively 10, 1000, 1,000,000 asses. The word as was used also for any whole which was to be divided into equal parts; and those parts were called unciae. Thus these words were applied not only to weight and money, but to measures of length, surface, and capacity, to inheritances, interest, houses, farms, and many other things. Hence the phrases haeres ex asse, the heir to a whole estate; haeres ex dodrante, the heir to three-fourths. The as was also called in ancient times assarius (sc. nummus), and in Greek τὸ ἀσσάριον. According to Polybius, the assarius was equal to half the obolus.
ASCĬA (σκέπαρνον), an adze. The annexed cut shows two varieties of the adze. The instrument at the bottom was called acisculus, and was chiefly used by masons.

ASCLĒPIEIA (ἀσκληπίεια), the name of festivals which were probably celebrated in all places where temples of Asclepius (Aesculapius) existed. The most celebrated, however, was that of Epidaurus, which took place every five years, and was solemnized with contests of rhapsodists and musicians, and with solemn processions and games.
ASCŌLĬASMUS (ἀσκωλιασμός, the leaping upon the leathern bag, ἀσκός) was one of the many kinds of amusements in which the Athenians indulged during the Anthesteria and other festivals in honour of Dionysus. Having sacrificed a he-goat to the god, they made a bag out of the skin, smeared it with oil, and then tried to dance upon it.
