Bab
Iranian religious leader, founder of the Babi religion and one of the central figures of Baha'i. The son of a merchant, he was influenced by the Shaykhi school of Shiite Islam. In 1844 he wrote a commentary on the sura of Joseph in the Quran and declared himself the Bab (Arabic: "gateway") to the hidden imam. Later he would claim to be the imam himself, and finally a divine manifestation. The same year he assembled 18 disciples, who spread the new faith in the various Persian provinces. He had popular support but was opposed by members of the religious class, and he was arrested near Tehran in 1847 and imprisoned. Meeting at Badasht in 1848, his followers, the Azali, formally broke with Islam. Mirza was executed by a firing squad at Tabriz in 1850.
Gabo
Russian-U.S. sculptor. He studied at the Univ. of Munich, and in 1913 he was introduced to avant-garde art in Paris by his brother, A. Pevsner. In 1920 the brothers returned to Russia and issued the Realist Manifesto, setting forth the principles of European Constructivism. Gabo produced abstract works of such unorthodox materials as glass, plastic, and wire to achieve a sense of movement. After some years in Europe, he settled in the U.S. in 1946 and taught at Harvard's architecture school. He received many awards and public commissions. A pioneer of the Constructivist movement, he was one of the earliest artists to experiment with kinetic sculpture.
lace
Ornamental openwork fabric formed by the looping, interlacing, braiding, or twisting of threads, originally primarily of linen. Almost all high-quality artistic lace is made by one of two techniques: needle lace involves a difficult technique that originated in Italy; bobbin lace is a more widespread craft that originated in Flanders. The art of lace is a European achievement. Fully developed lace did not appear before the Renaissance. By 1600 lace had become a fabric of luxury and an important article of commerce. The Industrial Revolution in the 19th cent. led to the use of machines to produce less-expensive lace made of cotton, and lace gradually disappeared from both men's and women's fashions. By 1920 the industry was dying. Fine handmade lace is still made in Belgium, Slovenia, and elsewhere, but chiefly as souvenirs.
lake
Relatively large body of slow-moving or standing water that occupies an inland basin. Lakes are most abundant in high N latitudes and in mountain regions, particularly those that were covered by glaciers in recent geologic times. The primary sources of lake water are melting ice and snow, springs, rivers, runoff from the land surface, and direct precipitation. In the upper part of lakes there is a good supply of light, heat, oxygen, and nutrients, well distributed by currents and turbulence. As a result, a large number of diverse aquatic organisms can be found there. The most abundant forms are plankton (chiefly diatoms), algae, and ...
