The “Maltese cross” is the modern name for the badge of the Knights of St. John of Jerusalem, later called the Knights of Malta. Originally, it was referred to as a “cross of eight points”, with each point said to represent one of the Beatitudes [Franklyn 118]. Though the Order was founded in 1113, this badge was not used in members’ armory until the 18th Century [Volborth 199, 211]. The Maltese cross was used as part of the full achievement, as for the arms of Pope Clement VII, 1523 [Galbreath’s Papal Heraldry, p.89]; therefore, it’s permitted for use in Society armory. The limbs should each be as wide as the space between them; they should converge to a central point, or very nearly.
