or their infant son, Charles Augustus.
During the protracted minority she administered the affairs of the duchy
with the greatest prudence, strengthening its resources and improving
its position in spite of the troubles of the Seven Years' War. She was a
patroness of art and literature, and attracted to Weimar many of the
most eminent men in Germany. Wieland was appointed tutor to her son; and
the names of Herder, Goethe and Schiller shed an undying lustre on her
court. In 1775 she retired into private life, her son having attained
his majority. In 1788 she set out on a lengthened tour through Italy,
accompanied by Goethe. She died on the 10th of April 1807. A memorial of
the duchess is included in Goethe's works under the title _Zum Andenken
der Furstin Anna-Amalia._

ANNABERG, a town of Germany, in the kingdom of Saxony, in the
Erzgebirge, 1894 ft. above the sea, 6 m. from the Bohemian frontier,
18-1/2 m. S. by E. from Chemnitz by rail. Pop. (1905) 16,811. It has
three Evangelical churches, among them that of St Anne, built 1499-1525,
a Roman Catholic church, several public monuments, among them those of
Luther, of the famous arithmetician Adam Riese, and of Barbara Uttmann.
Annaberg, together with the neighbouring suburb, Buchholz, is the chief
seat of the braid and lace-making industry in Germany, introduced here
by Barbara Uttmann in 1561, and further developed by Belgian refugees,
who, driven from their country by the duke of Alva, settled here in
1590. The mining industry, for which the town was formerly also famous
and which embraced tin, silver and cobalt, has now ceased. Annaberg has
technical schools for lace-making, commerce and agriculture, in addition
to high grade public schools for boys and girls.

ANNABERGITE, a mineral consisting of a hydrous nickel arsenate,
Ni3(AsO4)2 + 8H2O, crystallizing in the monoclinic system and
isomorphous with vivianite and erythrite. Crystals are minute and
capillary and rarely met with, the mineral occurring usually as soft
earthy masses and encrustations. A fine apple-green colour is its
characteristic feature. It was long known (since 1758) under the name
nickel-ochre; the name annabergite was proposed by H.J. Brooke and W.H.
Miller in 1852, from Annaberg in Saxony, one of the localities of the
mineral. It occurs with ores of nickel, of which it is a product of
alteration.
