Iris

the daughter of Thaumus ( i. e . wonder) and of the ocean nymph Electra ( i. e . splendour); was the godde of the rainbow, and as such the me enger of the gods, particularly of Zeus and Hera, the appearance of the rainbow being regarded as a sign that communications of good omen were pa ing between heaven and earth, as it was to Noah that they would continue to be kept up; she is represented as dre ed in a long wide tunic, over which hangs a light upper garment, and with golden wings on her shoulders.
