Did you know?

Iris, the Greek goddess of the rainbow, took messages from Mount Olympus to earth, and from gods to mortals or other gods, using the rainbow as her stairway. Iridescence is thus the glowing, shifting, colorful quality of a rainbow, also seen in an opal, a light oil slick, a butterfly wing, or the mother-of-pearl that lines an oyster shell.
