The Jerusalem cross (also known as "Crusaders' cross", "Five-fold Cross", or "cross-and-crosslets") is a heraldic cross and Christian cross variant consisting of a large cross potent surrounded by four smaller Greek crosses, one in each quadrant.
There are variants to the design, also known as "Jerusalem cross", with either the four crosslets also in the form of Crosses potent, or conversely with the central cross also in the form of a plain Greek cross.
It is not to be confused with the Lorraine cross, which has also been called the "Jerusalem cross".
While the symbol of the five-fold cross appears to originate in the 11th century, its association with the Kingdom of Jerusalem dates to the second half of the 13th century.
The symbolism of the five-fold cross is variously given as the Five Wounds of Christ, Christ and the four evangelists, or Christ and the four quarters of the world. The symbolism of five crosses representing the Five Wounds is first recorded in the context of the consecration of the St Brelade's Church under the patronage of Robert of Normandy (before 1035); the crosses are incised in the church's altar stone.
The "cross-and-crosslets" or "Tealby" pennies minted under Henry II of England during 1158–1180 have the "Jerusalem cross" on the obverse, with the four crosslets depicted as decussate (diagonal). Similar cross designs on the obverse of coins go back to at least the Anglo-Saxon period.
As the arms of the Kingdom of Jerusalem, the design is traditionally attributed to Godfrey of Bouillon himself. It was not used, however, by the Christian rulers of Jerusalem during the 12th century. A simple blazon of or, a cross argent is documented by Matthew Paris as the arms of John de Brienne, who had been king of Jerusalem during 1210–1212, upon John's death in 1237.
