Relic

Every culture, every religion, every era has enshrined otherwise regular objects with a significance which stretches beyond their literal importance. Whether the bone of a Catholic martyr, the tooth of a Buddhist lama, or the cloak of a Sufi saint, relics are material conduits to the immaterial world. Yet relics aren't just a feature of religion. The exact same sense of the transcendent animates objects of political, historical, and cultural significance.

From Abraham Lincoln's death mask to Vladimir Lenin's embalmed corpse, Emily Dickinson's envelopes to Jimi Hendrix's guitar pick, relics are the objects which the faithful understand as being more than just objects. Material things of sacred importance, relics are indicative of a culture's deepest values.
