Iris

   , IRIDESCENCE, IRIDIUM
   Iris was a pretty young girl who had the misfortune of being seen by the lustful Zeus. His jealous wife, Hera, turned Iris into a rainbow, and she became the goddess of the rainbow and the messenger of the gods. Whenever she had to convey a message to someone on earth, she took a convenient stairway down from heaven—a rainbow. Her name was derived from the Greek word for rainbow, and a sister word, iridescence, is a play of colors producing rainbow effects.
   Besides being poetically associated with the popular plant with large, beautifully colored flowers and with the rainbow, the name in English, is given to the colored membrane surrounding the pupil of the eye. The amount of pigment contained in the iris determines eye color. When there is very little pigment, the eye appears blue; with increased pigment, the shade becomes deep brown to black.
   Fleur de Us stands for "flower of the lily" in French (Us means lily). Fleur de Us is also the name of a design supposed to represent the white iris. The design became the emblem of the kings of France in the 1100s. Charles V changed the pattern to three golden fleur-de-lis on a blue field.
   The term irid is used also in indium, one of the densest terrestrial substances. It is a metallic element of the platinum group that, when combined with other elements, forms a substance with the various colors of the rainbow.
