The red cross was worn by the Knights Templar and inscribed on their seals and documents. This stylized and weathered version of their equal-armed cross was painstakingly designed using the the golden ratio and golden spiral. Eight historic Templar seals, including those showing the Dome of the Rock and Abraxas, are positioned around the arms of the cross. At the center of the cross is the five-petaled rose, symbolizing the Holy Grail. Whether you are a fan of the Da Vinci Code, Gabriel Knight, Grail lore, or Biblical studies, this shirt is sure to captivate.
