Greeks Painted Their Statuary
I was really fascinated to read this article about art students using ultra violet light, x-rays, and other light technology to take a look at ancient Greek and Roman statuary. Turns out they were brightly painted! Even after thousands of years, they were still able to figure out what colors they were, the delicate patterns, and even what the paint was made out of.
I had read in a book about Greek religion that in many religious groups, bathing, oiling and tending the statue of the Godform was one of the sacred tasks they performed. You can really understand how, with these bright colors, that might be a daunting and holy task.
