ĀRISTOCRĂTĬA (ἀριστοκρατία), signifies literally “the government of the best men,” and as used by Plato, Aristotle, Polybius, &c., it meant the government of a class whose supremacy was founded not on wealth merely, but on personal distinction. That there should be an aristocracy, moreover, it was essential that the administration of affairs should be conducted with a view to the promotion of the general interests, not for the exclusive or predominant advantage of the privileged class As soon as the government ceased to be thus conducted, or whenever the only title to political power in the dominant class was the possession of superior wealth, the constitution was termed an oligarchy (ὀλιγαρχία), which, in the technical use of the term, was always looked upon as a corruption (παρέκβασις) of an aristocracy. In the practical application of the term aristocracy, however, the personal excellence which was held to be a necessary element was not of a higher kind than what, according to the deeply-seated ideas of the Greeks, was commonly hereditary in families of noble birth, and in early times would be the ordinary accompaniments of noble rank, namely, wealth, military skill, and superior education and intelligence. It is to be noted that the word ἀριστοκρατία is never, like the English term aristocracy, the name of a class, but only of a particular political constitution.

ARMA, ARMĀTŪRA (ἔντεα, τεύχεα, Hom.; ὅπλα), arms, armour. Homer describes in various passages an entire suit of armour, and we observe that it consisted of the same portions which were used by the Greek soldiers ever after. Moreover, the order of putting them on is always the same. The heavy-armed warrior, having already a tunic around his body, and preparing for combat, puts on—1. his greaves (κνημῖδες, ocreae); 2. his cuirass (θώραξ, lorica), to which belonged the μίτρη underneath, and the zone (ζώνη, ζωστῆρ, cingulum), above; 3. his sword (ξίφος, ensis, gladius), hung on the left side of his body by means of a belt which passed over the right shoulder; 4. the large round shield (σάκος, ἀσπίς, clipeus, scutum), supported in the same manner; 5. his helmet (κόρυς, κυνέη, cassis, galea); 6. he took his spear (ἔγχος, δόρυ, hasta), or in many cases, two spears. The form and use of these portions are described in separate articles, under their Latin names. The annexed cut exhibits them all. Those who were defended in the manner which has now been represented are called by Homer aspistae (ἀσπισταί), from their great shield (ἀσπίς); also angemachi (ἀγχεμάχοι), because they fought hand to hand with their adversaries; but much more commonly promachi (πρόμαχοι), because they occupied the front of the army. In later times, the heavy-armed soldiers were called hoplitae (ὁπλίται), because the term hopla (ὄπλα) more especially denoted the defensive armour, the shield and thorax. By wearing these they were distinguished from the light-armed (ψιλοί, ἄνοπλοι, γυμνοί, γυμνῆται, γυμνῆτες), who, instead of being defended by the shield and thorax, had a much slighter covering, sometimes consisting of skins, and sometimes of leather or cloth; and instead of the sword or lance, they commonly fought with darts, stones, bows and arrows, or slings. Besides the heavy and light-armed soldiers, another description of men, the peltastae (πελτασταί), also formed a part of the Greek army, though we do not hear of them in early times. Instead of the large round shield, they carried a smaller one called the pelté (πέλτη), and in other respects their armour, though heavier and more effective than that of the psili, was much lighter than that of the hoplites. The weapon on which they principally depended was the spear. The Roman legions consisted, as the Greek infantry for the most part did, of heavy and light-armed troops (gravis et levis armatura). The preceding figure represents two heavy-armed Roman soldiers. All the essential parts of the Roman heavy armour (lorica, ensis, clipeus, galea, hasta) are mentioned together, except the spear, in a well-known passage of St. Paul (Eph. vi. 17).

ARMĀRĬUM, originally a place for keeping arms, afterwards a cupboard, in which were kept not only arms, but also clothes, books, money, and other articles of value. The armarium was generally placed in the atrium of the house.

ARMILLA (ψάλιον, ψέλιον, or ψέλλιον, χλιδών, ἀμφιδέα), a bracelet or armlet, worn both by men and women. It was a favourite ornament of the Medes and Persians. Bracelets do not appear to have been worn among the Greeks by the male sex, but Greek ladies had bracelets of various materials, shapes, and styles of ornament. They frequently exhibited the form of snakes, and were in such cases called snakes (ὄφεις) by the Athenians. According to their length, they went once, twice, or thrice round the arm, or even a greater number of times. The Roman generals frequently bestowed armillae upon soldiers for deeds of extraordinary merit.
