e fountain of St Lazare, a
work of the Renaissance. The hotel Rolin, a house of the 15th century,
contains the collections of the "Aeduan literary and scientific society."
The hotel de ville, containing a museum of paintings, the law-court and the
theatre are modern buildings. Autun is the seat of a bishopric, of
tribunals of first instance and of commerce, and has an ecclesiastical
seminary, a communal college and a cavalry school. Among the industries of
the town are the extraction of oil from the bituminous schist obtained in
the neighbourhood, leather manufacture, metal-founding, marble-working, and
the manufacture of machinery and furniture. Autun is the commercial centre
for a large part of the Morvan, and has considerable trade in timber and
cattle.

Autun (_Augustodunum_) succeeded Bibracte as capital of the Aedui when Gaul
was reorganized by Augustus. Under the Romans, it was a flourishing town,
covering double its present extent and renowned for its schools of
rhetoric. In the succeeding centuries its prosperity drew upon it the
attacks of the barbarians, the Saracens and the Normans. The counts of
Autun in 880 became dukes of Burgundy, and the town was the residence of
the latter till 1276. It was ravaged by the English in 1379, and, in 1591,
owing to its support of the League, had to sustain a siege conducted by
Marshal Jean d'Aumont, general of Henry IV.

AUTUNITE, or CALCO-URANITE, a mineral which is one of the "uranium micas,"
differing from the more commonly occurring torbernite (_q.v._) or
cupro-uranite in containing calcium in place of copper. It is a hydrous
uranium and calcium phosphate, Ca(UO_2)_2(PO_4)_2 + 8(or 12)H_2O. Though
closely resembling the tetragonal torbernite in form, it crystallizes in
the orthorhombic system and is optically biaxial. The crystals have the
shape of thin plates with very nearly square outline (89deg 17' instead of
90deg). An important character is the perfect micaceous cleavage parallel
to the basal plane, on which plane the lustre is pearly. The colour is
sulphur-yellow, and this enables the mineral to be distinguished at a
glance from the emerald-green torbernite. Hardness 2-2 1/2; specific
gravity 3.05-3.19. Autunite is usually found with pitchblende and other
uranium minerals, or with ores of silver, tin and iron; it sometimes coats
joint-planes in gneiss and pegmatite. Falkenstein in Saxony, St Symphorie
