The document discusses medieval art forms from AD 1000-1300 including coats of arms, triptychs, and stained glass windows. Coats of arms displayed family symbols and were used by kings and noblemen. Triptychs were altarpieces or devotional panels composed of three hinged sections that could open and close to tell stories. Stained glass windows illustrated stories and brought sunlight and colors into churches during the Medieval era from AD 1300.
