Aaron

Scholars have long been aware that the figure of Aaron as it is now found in the Pentateuch, or first five books of the Old Testament, is built up from several sources or layers of traditions. According to Julius Wellhausen, a German biblical scholar, and his followers, the Yahwist source was the oldest one, followed in order by the Elohist, Deuteronomist, and Priestly

Zoisite

Silicate mineral, calcium and aluminum silicate, Ca2Al3(SiO4)3OH, characteristic of regional metamorphism and of hydrothermal alteration of igneous rocks. A member of the epidote (q.v.) group of nesosilicates, zoisite occurs as white, green-brown, or gray crystals or masses in crystalline schists, often with amphibole minerals; in metamorphosed calcareous shales; very

Encaustic Painting

Painting technique in which pigments are mixed with hot, liquid wax. After all of the colours have been applied to the painting surface, a heating element is passed over them until the individual brush or spatula marks fuse into a uniform film. This “burning in” of the colours is an essential element of the true encaustic technique. Encaustic wax has many of the properties

Mountain, Tectonic processes that produce high elevations

As noted above, individual mountains, mountain ranges, mountain belts, and plateaus exist because tectonic processes have elevated terrains faster than erosion could destroy them. High elevations are created by three major processes: volcanism, horizontal crustal shortening as manifested by folding and by faulting, and the heating and thermal expansion of

Subiaco

Ancient (Latin)  Sublaqueum  town, Roma provincia, Lazio (Latium) regione, central Italy. It lies along the Aniene River, 1,345 feet (410 m) above sea level, about 45 miles (73 km) east of Rome. Its ancient name recalls its position below three small lakes where the emperor Nero built a villa. An inundation destroyed the lakes in 1305, and only traces remain of the villa. St. Benedict retired as a hermit (c. 494) to a cave, Sacro Speco (“Holy

Metamorphic Rock, Pyroxene-hornfels facies

Rocks of the pyroxene-hornfels facies are characteristically formed near larger granitic or gabbroic bodies at depths of a few kilometres or at pressures of a few hundred bars. The mineral assemblages are again largely anhydrous, but, unlike the sanidinite facies, the minerals reflect distinctly lower temperatures. One of the classic descriptions of such rocks
