The four children had rather peculiar names. The eldest girl was called Iris, which, as everybody ought to know, means rainbow-indeed, there was an Iris spoken of in the old Greek legends, who was supposed to be Hera's chief messenger, and whenever a rainbow appeared in the sky it was said that Iris was bringing down a message from Hera. The Iris of this story was a very pretty, thoughtful little girl, aged ten years. Her mother often talked to her about her name, and told her the story which was associated with it. The eldest boy was called Apollo, which also is a Greek name, and was supposed at one time to belong to the most beautiful boy in the world. The next girl was called Diana, and the youngest boy's name was Orion.
