 AGATHODAEMON, in Greek mythology, the "good spirit" of cornfields and vineyards. It was the custom of the Greeks to drink a cup of pure wine in his honour at the end of each meal (Aristophanes, Equites, 106). He was also regarded as the protecting spirit of the state and of individuals. He was often accompanied by  (good fortune), and in this aspect may be compared with the Roman Bonus Eventus (Pliny, Nat Hist. xxxvi. 23), and Genius. He is represented in works of art in the form of a serpent, or of a young man with a cornucopia and a bowl in one hand, and a poppy and ears of corn in the other.

AGATHODAEMON, of Alexandria, map designer, probably lived in the 2nd century Some MSS. of the Geography of Ptolemy contain twenty-seven maps, which are stated to have been drawn by Agathodaemon of Alexandria, who “delineated the whole world according to the eight books of Ptolemy’s geography.” As Ptolemy speaks of  to accompany his treatise, these maps were probably the work of a contemporary acting under his instructions. About 1470 Nicolaus Doris, a Benedictine monk, brought out a revised edition of them, the names being inserted in Latin instead of Greek.

AGATHON (c. 448–400 ), Athenian tragic poet, friend of Euripides and Plato, best known from his mention by Aristophanes (Thesmophoriazusae) and in Plato's Symposium, which describes the banquet given to celebrate his obtaining a prize for a tragedy (416). He probably died at the court of Archelaus, king of Macedonia. He introduced certain innovations, and Aristotle (Poetica, 9) tells us that the plot of his  was original, not, as usually, borrowed from mythological subjects.

AGATHYRSI, a people of Thracian origin, who in the earliest historical times occupied the plain of the Maris (Maros), in the region now known as Transylvania. Thyrsi is supposed to be a Scythian form of  (Trausi), a Thracian tribe mentioned by Stephanus of Byzantium. They are described by Herodotus (iv. 104) as of luxurious habits, wearing gold ornaments (the district is still auriferous) and having wives in common. They tattooed their bodies (picti, Aeneid iv. 136), degrees of rank being indicated by the manner in which this was done, and coloured their hair dark blue. Like the Gallic Druids, they recited their laws in a kind of sing-song to prevent their being forgotten, a practice still in existence in the days of Aristotle (Problemata, xix. 28). Valerius Flaccus (Argonautica vi. 135) calls them Thyrsagetae, probably in reference to their celebration of orgiastic rites in honour of some divinity akin to the Thracian Dionysus. In later times the Agathyrsi were driven farther north, and their name was unknown to the Romans in their original home.

AGAVE, a large botanical genus of the natural order Amaryllidaceae, chiefly Mexican, but occurring also in the southern and western United States and in central and tropical South America. The plants have a large rosette of thick fleshy leaves generally ending in a sharp point and with a spiny margin; the stout stem is usually short, the leaves apparently springing from the root. They grow slowly and flower but once after a number of years, when a tall stem or “mast” grows from the centre of the leaf-rosette and bears a large number of shortly tubular flowers. After development of fruit the plant dies down, but suckers are frequently produced from the base of the stem which become new plants. The most familiar species is Agave americana (see fig.), a native of tropical America, the so-called century plant or American aloe (the maguey of Mexico). The number of years before flowering occurs depends on the vigour of the individual, the richness of the soil and the climate; during these years the plant is storing in its fleshy leaves the nourishment required for the effort of flowering. During the development of the inflorescence there is a rush of sap to the base of the young flower-stalk. In the case of A. americana and other species this is used by the Mexicans to make their national beverage, pulque; the flower shoot is cut out and the sap collected and subsequently fermented. By distillation a spirit called mescal is prepared. The leaves of several species yield fibre, as for instance, A. rigida var. sisalana, (q.v.), A. decipiens, false sisal hemp; A. americana is the source of pita fibre, and is used as a fibre plant in Mexico, the West Indies and southern Europe. The flowering stem of the last named, dried and cut in slices, forms natural razor strops, and the expressed juice of the leaves will lather in water like soap. In the Madras Presidency the plant is extensively used for hedges along railroads. Agave americana, century plant, was introduced into Europe about the middle of the 16th century and is now widely cultivated for its handsome appearance; in the variegated forms the leaf has a white or yellow marginal or central stripe from base to apex. As the leaves unfold from the centre of the rosette the impression of the marginal spines is very conspicuous on the still erect younger leaves. The plants are usually grown in tubs and put out in the summer months, but in the winter require to be protected from frost. They mature very slowly and die after flowering, but are easily propagated by the offsets from the base of the stem.

AGDE, a town of southern France, in the department of Herault, on the left bank of the river of that name, 2 m. from the Mediterranean Sea and 32 m. S.W. of Montpellier on the Southern railway. Pop. (1906) 7146. The town lies at the foot of an extinct volcano, the Montagne St Loup, and is built of black volcanic basalt, which gives it a gloomy appearance. Overlooking the river is the church of St André, which dates partly from the 12th century, and, till the Revolution, was a cathedral. It is a plain and massive structure with crenelated walls, and has the aspect of a fortress rather than of a church. The exterior is diversified by arched recesses forming machicolations, and the same architectural feature is reproduced in the square tower which rises like a donjon above the building. The Canal du Midi, or Languedoc canal, uniting the Garonne with the Mediterranean, passes under the walls of the town,
