One interpretation of the 'sharp' pointed cross is of four fishtail. The fish symbol was adopted by the early Christian church. A Vert (green) version of the Maltese Cross is the St. Lazarus Cross used by the Military and Hospitaller Order of Saint Lazarus of Jerusalem. The Armenia Cross is another 8- pointed fishtail cross.
A further interpretation is of four arrow- heads. With this military/ fighting association, the cross was the emblem of the knights of St. John, who were driven from Rhodes to the island of Malta by the Turks. The eight-pointed cross is a symbol used by the knights to denote the eight obligations or aspirations of the knight-the eight beatitudes. Because of the knights of St. John connection, this cross is also called St. John's cross. Maltese cross with 8 points emphasized is a symbol of St. John Baptist. Is has become famous as the badge of the order of St. John of Jerusalem (commonly called the hospitalers). In heraldry it is shown as silver and red or as silver on black. Depending on its use.
