Cross

From Free net encyclopedia

For other uses, see Cross (disambiguation).

A cross is a geometrical figure consisting of two lines or bars intersecting each other at a 90° angle, dividing one or two of the lines in half. The lines usually run vertically and horizontally; if they run diagonally, the design is technically termed a saltire.

The cross is one of the most ancient human symbols, and is used by many religions, most notably Christianity. It is frequently a representation of the division of the world into four elements (or cardinal points), or alternately as the union of the concepts of divinity, the vertical line, and the world, the horizontal line (Koch, 1955).

History

It is not known when the first cross image was made; after circles, crosses are one of the first symbols drawn by children of all cultures. There are many cross-shaped incisions in European cult caves, dating back to the earliest stages of human cultural development in the stoneage. Like other symbols from this period, their use continued in the Celtic cultures in Europe. Other early images of crosses were found in the Central Asian steppes, and some were found in Altay. The cross in the old Altaic religion called Tengriism symbolizes the god Tengri and the three-world cosmology; it wasn't an elongated "dagger" cross, instead resembling a plus sign (+).

The first Christian books from Armenia and Syria contained evidence that the cross originated with horsemen from the east, possibly referring to the first Turkic peopleTemplate:Fact. In old Armenian temples, some stylistic Turkic influences are found in cross symbolsTemplate:Fact. Named animal, the symbol was found in the plans of temples, with the pillars from above looking like an additional cross.

As markings

Written crosses are used for many different purposes, particularly in mathematics.

The Roman numeral for ten is X.
In the Latin alphabet, the letter X and the miniscule form of t are crosses.
The Chinese character for ten is 十 (see Chinese numerals).
The dagger or obelus (†)
The addition (or plus) sign (+) and the multiplication (or times) sign (×).
If n≥1 is an integer, the numbers coprime to n, taken modulo n, form a group with multiplication as operation; it is written as (Z/nZ)^× or Z_n^*.

A cross is often used as a check mark because it can be clearer, easier to create with an ordinary pen or pencil, and less obscuring of the text or image that is already present than a large dot. It also allows marking a position more accurately than a large dot.

A large cross through a text often means that it is wrong or should be considered deleted.

Cross Name	Description	Picture
Ankh	Also known as the Key of the Nile, the Looped Tau Cross, and the Ansated Cross. It was an Ancient Egyptian symbol of life. Sometimes given a Latin name if it appears in specifically Christian contexts, such as the crux ansata ("handled cross").	Image:Ankh.png
Christian cross	Also known as the Latin cross or crux ordinaria. It is the most common symbol of Christianity, intended to represent the redeeming martyrdom of Jesus when he is crucified on the True Cross in the New Testament.	Image:Christian cross.svg
Coptic Cross	A small circle from which emanate four branches of equal length, with angled T shapes in the corner, cross-pieces outward, representing the nails used in Jesus' crucifixion.	Image:Coptic-Cross-so-called.png
Greek cross	Also known as the crux immissa quadrata. Has all branches of equal length.	Image:Greek cross.svg
High cross	Free-standing Celtic crosses in the United Kingdom and the Republic of Ireland, very common in churches and graveyards.	Image:Ccross.png
Labarum	Constantine's Labarum is also known as a Chrismon, or monogram of the name Jesus Christ. Several other forms of Chrismons exist.	Image:Labarum.png

Saint Andrew's Cross	Used in Scotland's national flag, it is also called the Saltire, the Boundary Cross (because it was used by the Romans as a barrier) and the crux decussata. Saint Andrew is believed to have suffered a martyr's death on such a cross, hence its name. The cross doesn't have to be at this particular angle to qualify as a saltire; the symbol X can also be considered a St. Andrew's Cross.	Image:Flag of Scotland.svg
Saint Peter's Cross	An upside-down Latin cross, based on a tradition that holds that Saint Peter was martyred by being crucified upside-down. Today it is often associated with anti-Christian or Satanic groups.	Image:Peter's Cross.svg

The top line is said to represent the headboard, and the bottom, slanted line represents the footrest, wrenched loose by Jesus' writhing in intense agony. The letters IC XC found at the end of the main arm of some Slavonic Crosses are a Christogram, representing the name of Jesus Christ.	Image:Slavcross.gif

It is traditionally oriented so that a main line is horizontal, though it is occasionally rotated at forty-five degrees, and the Hindu version is often decorated with a dot in each quadrant.

In heraldry

These crosses are ones used exclusively or primarily in heraldry, and do not necessarily have any special meanings commonly associated with them. Crosses that are used in heraldry but also commonly in other contexts are not listed here.

Cross name	Description	Picture
The cross as heraldic "ordinary"	A simple heraldic cross (the default if there are no additional specifying words) has arms of roughly equal length, artistically proportioned to the particular shape of the shield, which extend to the edges of the shield. Illustrated is the blazon "Azure, a cross Or" (i.e. a gold cross on a blue shield). A cross which does not extend to the edges of the shield is humetty, in heraldic terminology.	Image:Azure-Cross-Or-Heraldry-small.png
Cross bottony	A cross with the ends of the arms bottony (or botonny), i.e. shaped like an architectural trefoil. It occurs counterchanged on the flag of Maryland.	Image:Cross-Bottony-Heraldry.png
Cross crosslet	A cross with the ends of each arm crossed.	Image:Cross-Crosslet-Heraldry.png
Crusaders' cross	Also known as the Jerusalem cross. This cross was the symbol of the Crusader Kingdom of Jerusalem, which existed for almost two hundred years after the First Crusade. The four smaller crosses are said to symbolize either the four books of the Gospel or the four directions in which the Word of Christ spread from Jerusalem. Alternately, all five crosses can symbolize the five wounds of Christ during the Passion. This symbol is also used in the flag of Georgia.	Image:Crusaders.gif
Cross flory	A cross with the ends of the arms flory (or fleury), i.e. having a shape somewhat like a fleur-de-lys.	Image:Cross-Flory-Heraldry.png
Cross fourchee	One form of the heraldic cross fourchee (fourchée, fourchy) or cross fourche (meaning "forked").	Image:Cross-Fourchee-Heraldry.png
Jerusalem cross	A variant of the Crusaders' cross with cross potent.	Image:Cross-Jerusalem-Potent-Heraldry.png
Maltese cross	With arms which narrow towards the center, and are indented at the ends. The "eight-pointed cross" (with no curved lines).	Image:Maltese-Cross-Heraldry.png
Cross moline	In a cross moline, the ends of the arms are split and curved back.	Image:Cross-Moline-Heraldry.png
Cross patonce	A cross patonce is more or less intermediate between a cross pattée and a cross flory.	Image:Cross-Patonce-Heraldry.png
Cross pattée	A cross pattee (pattée, patty) has arms narrowing towards the centre, but with non-indented ends. See the cross pattée article for discussion of variant forms. See also Iron Cross.	Image:Cross-Pattee-Heraldry.png
Cross pommee	A cross pommee (pommée, pommy) has a circular knob at the end of each arm.	Image:Cross-Pommee-Heraldry.png
Cross potent	This cross has a crossbar at the end of each of its arms. "Potent" is an old word for a crutch, and is used in heraldic terminology to describe a T shape.	Image:Cross-Potent-Heraldry.png
Quadrate	A cross with a square at the intersection point.	Image:Quadrate.gif
Cross triple parted and fretted	In heraldry, a "cross triple parted and fretted" (or "treble parted and fretted") is interlaced. Here, a version which is "Or on an Azure field" (gold on blue) is shown.	Image:Cross-Triple-Parted-Fretted-Or.png
Cross voided	A "cross voided throughout", also known as the Gammadia, can be seen as a Greek cross with its centre lines removed, or as composed of four angles (L shapes) separated by a thin space. So the name "gammadia" refers to its being made up of four shapes similar to a capital Greek letter gamma; the word gammadion can also refer to a swastika.	Image:Cross-Voided-small-.png

There are numerous other variations on the cross in heraldry. See heraldry for background information.

The semi-classic book "A Glossary of Terms Used in Heraldry" by James Parker (1894) is online, and contains much information about variants of crosses used in heraldry.
