Iris
Iris, the goddess of the rainbow that bridged heaven and earth, flew on the wind. She arrived like a breath of fresh air, bringing hope.
She helped the pregnant Leto by discreetly bringing someone to assist her with a protracted labour.
A minor goddess, she was often used by Zeus as a carrier of messages. However, when he sent her to Demeter after the abduction of Persephone, the grieving mother did not heed her.
Iris was much involved in the Trojan war. Though she did not take sides, she helped Aphrodite, Achilles and Hector at various times during the conflict. At times she took the guise of a mortal, and then again, she appeared in all her rainbow glory.
