- Kingdom containing multicellular organisms having cells bound by a plasma membrane and organized into tissue and specialized tissue systems that permit them to either move about in search of food or to draw food toward themselves. Unable to make their own food within themselves, as photosynthetic plants do, they rely on consuming preformed food. They possess a nervous system with sensory and motor nerves, enabling them to receive environmental stimuli and to respond with specialized movements.
- An extraterrestrial body consisting of a frozen mass and rock debris that travels around the Sun in a highly elliptical orbit; it generally developes a diffuse gaseous envelope and a long luminous tail when near the Sun.
- Roman silver coins originally valued at ten asses, later debased in value and purity; in use from the late 3rd century BCE until the mid-3rd century CE.
- Refers to the period in history and the style of art that developed when the Roman Republic ceased to exist and Rome expanded its territory and was ruled by emperors. The period is generally considered to begin with Octavian's victory at the Battle of Actium in 31 BCE, and to last through the rule of the Severans. For later emperors, see "Late Antique." For the period and culture of the Holy Roman Empire, use "Holy Roman Imperial." Note that some classifications include the Tetrarchic, Constantinian, and the Holy Roman Empire in the "Roman Empire."
- Pure metallic element having symbol Ag and atomic number 47; a malleable, ductile, white metal with characteristic sheen, considered a precious metal. Silver is widely distributed throughout the world, occurring rarely as metallic silver (in Peru, Norway) but more often as silver-gold alloys and silver ore. Today silver is obtained as a byproduct in the refinement of gold, lead, copper, or zinc ores. Silver was smelted from the ore galena as early as 3800 BCE. As a pure metal, silver is second to gold in malleability and ductility, can be polished to a highly reflective surface, and used -- typically in an alloy -- in jewelry, coinage, photography, mirrors, electrical contacts, and tableware.
- Order containing around 180 species in two families of nocturnal raptorial birds with hooked beaks, strong talons, and soft plumage. All owls have the same general appearance, which is characterized by a flat face, small hooked beak, short tail, round wings, and large, forward-facing eyes. The bird became associated with Athena, the Greek goddess of wisdom and also owls became symbolic of intelligence because it was thought that they could forsee events. Also, because of their nocturnal existence and hooting sounds, owls have also been symbols associated with the occult. In the Middle Ages, the owl became a symbol of the darkness before the coming of Christ.
