This blue pigment was used from the days of ancient Egypt until the end of the Roman Empire, but was not made after this time. So how could it turn up in a 12th Century church?

Second, an accidental discovery of a stable and chemically "benign" blue color compound, a formula the ancients searched for in vain for thousands of years!  I found this story by accident :)
