Albigenses (al-bi-jen′sēz), a neo-Manichæan sect which spread widely in the south of France and elsewhere about the twelfth century, and which differed in doctrine and practice from the Roman Catholic Church, by which they were subjected to severe persecution. They are said to have been so named from Albi, on the banks of the Tarn, a tributary of the Garonne, where,

and about Toulouse, Narbonne, &c., they were numerous. They were also known as Catharists (q.v.) and their doctrines were similar to those of several other religious sects such as the Gnostics, Manichæans, and Bogomils. Among the principal doctrines of the Albigenses was the belief in the existence of two principles, good and evil, the creators of the spiritual and material worlds. Since all matter is under the control of the evil principle, maintained the Albigenses, all flesh is evil. The extinction of bodily life, therefore, the deliverance of the soul from the prison-house of the body, should be the aim of man. Suicide by means of starvation was consequently highly meritorious. It is admitted even by Catholic writers (see Catholic Encyclopædia, vol. i, p. 268) that the Albigenses were principally antisacerdotal and opposed to the Roman Church on account of the scandalous life led by the Catholic clergy. A crusade was begun against them, and Count Raymond VI of Toulouse for tolerating them, in 1209, the army of the cross being called together by Pope Innocent III. The war was carried on with a cruelty which reflected deep disgrace upon the Catholic Church. Béziers, the capital of Raymond's nephew Roger, was taken by storm, and 20,000 of the inhabitants, without distinction of creed, were put to the sword. Simon de Montfort, the military leader of the crusade, was equally severe towards other places in the territory of Raymond and his allies. After the death of Raymond VI, in 1222, his son, Raymond VII, was obliged, notwithstanding his readiness to do penance, to defend his inheritance against the papal legates and Louis VIII of France. When hundreds of thousands had fallen on both sides, a peace was made in 1229, by which Raymond was obliged to cede Narbonne with other territories to Louis IX, and make his son-in-law, a brother of Louis, his heir. The heretics were now delivered up to the proselytizing zeal of the Dominicans, and to the courts of the Inquisition, by which means it was brought about that the Albigenses disappeared after the middle of the thirteenth century.

Albinos (al-bī′nōz), the name given to those persons from whose skin, hair, and eyes, in consequence of some defect in their organization, the dark colouring matter is absent. The skin of albinos, therefore, whether they belong to the white, Indian, or negro races, is of a uniform pale milky colour, their hair is white, while the iris of their eyes is pale rose colour, and the pupil intensely red, the absence of the dark pigment allowing the multitude of blood-vessels in these parts of the eye to be seen. For the same reason their eyes are not well suited to endure the bright light of day, and they see best in shade or by moonlight. The peculiarity of albinism or leucopathy is hereditary and not confined to the human race, having been observed also in horses, rabbits, rats, mice, &c., birds (white crows or blackbirds are not particularly uncommon), and fishes. Albinos are not of necessity lacking in mental vigour or capacity. Cf. Karl Pearson, A Monograph on Albinism in Man.

Al′bion (Celtic Albainn), the earliest name by which the island of Great Britain was known, employed already by writers of the sixth century B.C., who speak not of Britannia but of the land of the Albiones, and in poetry still used for Great Britain. It is connected with Lat. albus, white, on account, perhaps, of the chalk cliffs of Dover. The same word as Albany, Albyn.

Al′bite, or Soda-felspar, a mineral, a kind of felspar, usually of a white colour, to which property it owes its name (Lat. albus, white), but occasionally bluish, greyish, greenish, or reddish white.

Albizzia (al-bit′si-a), a genus of leguminous trees and shrubs, allied to the genus Acacia, with doubly-pinnate leaves and white, yellow, or red flowers often in globular heads, and broad, straight, flat pods. They number over fifty species, and inhabit tropical and subtropical Asia, Africa, and Australia. A. lophanta, a native of south-western Australia, has a bark that contains tannin. A. Lebbek, a native of Asia and Africa, yields valuable timber, and in Egypt is much cultivated as a shade tree. A. Julibrissin, a tree with rose-red flowers, is found in Asia and Africa, and has been introduced into Southern Europe.

Al′boin, King of the Lombards, succeeded his father Audoin in 561, and reigned in Noricum and Pannonia. Narses, the general of Justinian, sought his alliance, and received his aid, in the war against Totila, King of the Ostrogoths. Alboin afterwards (in 568) undertook the conquest of Italy, where Narses, who had subjected this country to Justinian, offended by an ungrateful Court, sought an avenger in Alboin, and offered him his co-operation. After a victorious career in Italy he was slain at Verona, in 573 or 574, by an assassin, instigated by his wife Rosamond, whose hatred he had incurred by sending her, in one of his fits of intoxication, a cup wrought from the skull of her father, and forcing her to drink from it.

Alborak, in Mohammedan mythology, the animal said to have been brought by the angel Gabriel to carry Mohammed to the seventh heaven. It had the face of a man, the body of a horse, the wings of an eagle, and spoke with a human voice.
