A cross potent (plural: crosses potent), also known as a crutch cross, is a form of heraldic cross with crossbars at the four ends. In French, it is known as croix potencée, in German as a Krückenkreuz, all translating to "crutch cross".

Name

Potent is an old word for a crutch, from a late Middle English alteration of Old French potence "crutch" The term potent is also used in heraldic terminology to describe a T-shaped alteration of vair, and potenté is a line of partition contorted into a series of 'T' shapes. In heraldic literature of the 19th century, the cross potent is also known as the "Jerusalem cross" due to its occurrence in the attributed coat of arms of the Kingdom of Jerusalem. This convention is reflected in Unicode, where the character ☩ (U+2629) is named CROSS OF JERUSALEM. The name Jerusalem cross is more commonly given to the more complex symbol consisting of a large Greek cross or cross potent surrounded by four smaller Greek crosses.

History

The "cross potent" shape is found in pottery decorations in both the European and the Chinese Neolithic. In Chinese bronze inscriptions, the glyph ancestral to the modern Chinese character 巫 "shaman, witch" has the shape of a cross potent, interpreted as representing a cross-like "divining rod" or similar device used in shamanistic practice. The cross potent as a Christian cross variant is used on Byzantine coins of the 7th century, under the Heraclian dynasty, mostly as a "Calvary cross potent", i.e. a cross potent standing on a number of steps. A Tremissis of Heraclius, dated c. 610–613, also shows the cross potent without the steps. A cross potent, or cross patty, is already shown on a Tremissis of Theodosius II (first half of the 5th century). Use of the cross potent in heraldry is revived in the 19th to early 20th century, and then as an emblem for Roman Catholicism directly based on the Jerusalem cross.

Modern use

Upon the passage of the 1924 Schilling Act the cross potent was used as a national symbol of the Austrian First Republic, minted on the back of the Groschen coins. In 1934 it became the emblem of the Federal State of Austria, adopted from the ruling Fatherland's Front, the Catholic authoritarian traditionalist organisation led by Chancellor Engelbert Dollfuss. A reference to the Jerusalem Cross, it served as a counter-symbol to both the Nazi swastika and the communist hammer and sickle, as the Fatherland Front was both anti-Nazi and anti-Communist. The symbol was also adopted by the Russian far-right People's National Party and the obscure Cambodian militia MONATIO in the 1970s. It was also used as a symbol for independence by the Nationalist Party of Puerto Rico during the first half of the 20th century, an organization was a Roman Catholic movement that was traditionalist, anti-communist, anti-American and anti-imperialist and sought to liberate the archipelago of Puerto Rico from American control through armed struggle. Today, the cross potent is used by many, mostly Roman Catholic, Scouting and Guiding organisations in their logos and insignia. It is currently used in the coats of arms of the Santa Cruz Department in Bolivia, and of the Wingolf Christian student fraternities in Germany, Austria and Estonia. A white cross potent on a black background was a candidate in the 2015 Hello Internet Podcast Flag Referendum. The New Columbia Movement, a self proclaimed Christian nationalist organization, uses the cross potent in its flag.
