According to some poets, Iris is described as the rainbow itself, while Servius implies that the rainbow was merely the road on which she travelled which appeared when the need arose and disappeared when it was not needed. Regarding her worship, the Delians offered her cakes made of wheat and honey and dried figs on the island of Hecate. In ancient Greek vase painting, she appears as a beautiful young woman, standing and dressed in a long wide tunic with a light upper garment and wings attached to her shoulders. She is found carrying the herald’s staff in her left hand or appears to fly on their wings with sandals on her feet along with the staff and the pitcher in her hand and compared to a swift footed storm wind messenger.
According to German, myths the rainbow was considered as a bowl that God used during his creation to color the world while others thought that it was a magnificent gift of nature. The ancient Arabians believed it was a tapestry woven by the south wind while the Incas thought that it was a gift from their sun god. The Buddhist identified the rainbow to the seven regions of the earth due to its seven colors and believed it as the next highest state of achievement before Nirvana, the place very one and all individuals meet their end. The Hindus believe that the rainbow represents the archer’s bow of their god of war and that the god used the bow to send arrows of lightening to kill demons who threatened their land and their people. In Islam, it is believed to have only four colors instead of the seven colors, namely blue, green, red and yellow which are related to fire, earth, water and wind. The Native American tribes considered the rainbow as the drinking fountain for all souls of heaven while other believed it to be a bridge between the world of humans and the world of gods though not heaven and still others believed it to be merely a pathway which the gods used.
