The Christian cross symbol is often shown in different shapes and sizes, in many different styles. It may be used in personal jewelry, or used on top of church buildings. It is shown both empty and in crucifix form, that is, with a figure of Christ, often referred to as the corpus (Latin for "body"), affixed to it.
The Greek cross is the most common Christian forms, the cross with arms of equal length, in common use by the 4th century. The standard Latin cross (with an elongated descending arm) is encoded at U+271D✝latin cross.
Roman Catholic, Anglican and Lutheran depictions of the cross are often crucifixes, in order to emphasize that it is Jesus that is important, rather than the cross in isolation. Large crucifixes are a prominent feature of some Lutheran churches, as illustrated in the article Rood. However, some other Protestant traditions depict the cross without the corpus, interpreting this form as an indication of belief in the resurrection rather than as representing the interval between the death and the resurrection of Jesus.
Crosses are a prominent feature of Christian cemeteries, either carved on gravestones or as sculpted stelas. Because of this, planting small crosses is sometimes used in countries of Christian culture to mark the site of fatal accidents, or to protest alleged deaths.
In Catholic countries, crosses are often erected on the peaks of prominent mountains, such as the Zugspitze or Mount Royal, so as to be visible over the entire surrounding area.
Also called an archiepiscopal cross or a crux gemina. A double cross, with the two crossbars near the top. The upper one is shorter, representing the plaque nailed to Jesus' cross. Similar to the Cross of Lorraine, though in the original version of the latter, the bottom arm is lower. The Eastern Orthodox cross adds a slanted bar near the foot.
An X-shaped cross associated with St. Andrew, patron of Scotland, and so a national symbol of that country. The shape is that of the cross on which Saint Andrew is said to have been martyred. Also known as St. Andrew's Cross or Andrew Cross.
Shaped like the letter T surmounted by an oval or circle. Originally the Egyptian symbol for "life", it was adopted by the Copts (Egyptian Christians). Also called a crux ansata, meaning "cross with a handle".
A cross with four arms of equal length which widen to a hammer shape at the outside ends. Each arm has a triangular panel inscribed in a triquetra (three-cornered knot) pattern. There is a small square panel in the center of the cross. A symbol of the Anglican and Episcopal Churches.
A Greek cross with 4 Cyrillic S's (C) in each of its angles, which represent the imperial motto of the Palaiologos dynasty when he resurrected the Byzantine Empire: King of Kings, Ruling Over Kings (βασιλεὺς βασιλέων, βασιλεύων βασιλευόντων - Basileus Basileōn, Basileuōn Basileuontōn). A national symbol of Serbia and symbol of the Serbian Orthodox Church.
Also known as Russian cross, Slavic or Slavonic cross. A three-barred cross in which the short top bar represents the inscription over Jesus' head, and the lowest (usually slanting) short bar, placed near the foot, represents his footrest (in Latin, suppedaneum). This cross existed in a slightly different form (with the bottom crossbeam pointing upwards) in Byzantium, and it was changed and adopted by the Russian Orthodox Church and especially popularized in the East Slavic countries.
A cross on a flat base to rest upon the altar of a church. The earliest known representation of an altar cross appears in a miniature in a 9th-century manuscript. By the 10th century such crosses were in common use, but the earliest extant altar cross is a 12th-century one in the Great Lavra on Mt. Athos. Mass in the Roman Rite requires the presence of a cross (more exactly, a crucifix) "on or close to" the altar. Accordingly, the required cross may rest on the reredos rather than on the altar, or it may be on the wall behind the altar or be suspended above the altar.
