PARIS (AP) -- An ancient relic that many Christians revere as Jesus Christ's "Crown of Thorns" has made a special public appearance at Notre Dame Cathedral in Paris.
The crown -- a circular band of branches encased in a gilded, golden tube -- is being displayed for three days to mark the 800th anniversary of the birthday and christening of King Louis IX of France, who acquired it in 1239.
The relic was first mentioned by Jerusalem pilgrims in the 5th century and was transferred to Constantinople in the 10th century.
The artifact has appeared in special ceremonies a handful of times in the last hundred years: in 1997, and in 1939 on the eve of World War II, to celebrate seven centuries since it came to France.
