Jerusalem cross

Jerusalem cross based on a cross potent (as commonly realised in early modern heraldry)

The Jerusalem cross (also known as "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. Widely popularized during the Christian Crusades in the Holy Land, it was used as the emblem and coat of arms of the Kingdom of Jerusalem from the 1280s.
