Agathocles (a-gath′o-klēz), a Sicilian Greek, one of the boldest adventurers of antiquity, born 361 B.C. By his ability and energy, and being entirely unscrupulous, he raised himself from being a potter to being tyrant of Syracuse and master of Sicily. Wars with the Carthaginians were the chief events of his life. He died at the age of seventy-two.

Ag′athon, a Greek tragic poet, a friend of Euripides, and contemporary with Socrates and Alcibiades, born about 445 B.C., died about 402 B.C. The banquet which he gave to celebrate his first dramatic victory was made the groundwork of Plato's Symposium.

Agave (a-gā′vē), a genus of plants, nat. ord. Amaryllidaceæ (which includes the daffodil and narcissus), popularly known as American aloes. They are generally large, and have a massive tuft of fleshy leaves with a spiny apex. They live for many years—ten to seventy according to treatment—before flowering. When this takes place, the tall flowering stem springs from the centre of the tuft of leaves, and grows very rapidly until it reaches a height of 15, 20, or even 40 feet, bearing towards the end a large number of flowers. The best-known species is A. americāna, known as the Maguey or 'tree of wonders', introduced into Spain in 1561, and now extensively grown in the warmer parts of this continent as well as in Asia (India in particular). This and other species yield various important products, the chief being the fibre obtained by maceration from the leaves and roots, and known commercially as American aloe, pita flax, or vegetable silk. The sap when fermented yields a beverage resembling cider, the pulque beer of the Spaniards, or is distilled into an intoxicating spirit (Mezcal or Aguardiente). The leaves are used for feeding cattle; the fibres of the leaves are formed into thread, cord, and ropes, and are also good material for paper-making; an extract from the leaves is used as a substitute for soap; slices of the withered flower-stem are used as razor-strops.

Agde (a˙gd), a seaport of southern France, department of Hérault, with a cathedral, an ancient and remarkable structure. The trade, chiefly coasting, is extensive. Pop. 9265.

Age, a period of time representing the whole

or a part of the duration of any individual thing or being, but used more specifically in a variety of senses. In law age is applied to the periods of life when men and women are enabled to do that which before, for want of years and consequently of judgment, they could not legally do. A male at twelve years old may take the oath of allegiance; at fourteen is at years of discretion, and therefore may choose his guardian or be an executor, although he cannot act until of age; and at twenty-one is at his own disposal, and may alienate and devise his lands, goods, and chattels. In English law a male at fourteen and a female at twelve may consent or disagree to marriage, but it cannot be celebrated without the consent of the parents or guardians until the parties are of age. A female at fourteen is at years of legal discretion, and may choose a guardian; at seventeen may be an executrix; and at twenty-one may dispose of herself and her lands. So that full age in male or female is twenty-one years, which age is completed on the day preceding the anniversary of a person's birth, who till that time is an infant, and so styled in law. In France majority is attained at twenty-one, whilst the marriageable age is eighteen for males and fifteen for females, subject to consent of parents or guardians. In England no one can take a seat in Parliament under twenty-one, be ordained a priest under twenty-four, nor made a bishop under thirty. In France a seat in the Chamber of Deputies may be taken only at twenty-five and in the Senate at forty. The law of Scotland divides life into three periods—pupilarity, minority, and majority. The first extends up to the time of legal puberty, that is, twelve years for a female and fourteen for a male, when they may marry; the second extends from this point up to twenty-one years, which is the time when majority is attained.

The term is also applied to designate the successive epochs or stages of civilization in history or mythology. Hesiod speaks of five distinct ages:—1. The golden or Saturnian age, a patriarchal and peaceful age. 2. The silver age, licentious and wicked. 3. The brazen age, violent, savage, and warlike. 4. The heroic age, which seemed an approximation to a better state of things. 5. The iron age, when justice and honour had left the earth. The term is also used in such expressions as the dark ages, the middle ages, the Elizabethan age, &c.

The Archæological Ages or Periods are three—the Stone Age, the Bronze Age, and the Iron Age, these names being given in accordance with the materials chiefly employed for weapons, implements, &c., during the particular period. The Stone Age of Europe has been subdivided into two—the Palæolithic or earlier, and Neolithic or later. The word age in this sense has no reference to the lapse of time—or not necessarily so—but simply refers to the stage at which a people has arrived in its progress towards civilization; thus there are races still in their stone age. The Palæolithic or earlier stone age in Europe was doubtless immensely earlier than the Neolithic, the latter being marked by implements of much greater finish than the former. See Stone Age.
