The “cross of St. Brigid” is based on a woven straw design, used by the Irish on St. Brigid’s Day, but dating from pagan fertility rituals. Such rituals used several forms of St. Brigid’s cross; the illustration shows a “straight-armed” cross. Its use in heraldry is unique to the Society, and is considered a step from period practice.
