reliquary

Reliquary: A reliquary is a container for relics. They were designed in many forms, and were usually made from gilt-copper. They were essentially boxes with highly extravagant designs. These reliquaries were important to medieval culture because relics were physical evidence of the religion that was such a large part of everyday life. This is the reliquary //Chasse St. Taurin// and is a good example of the extravagance and beauty in these boxes.
