In this booklet Jill Dudley speaks of the light that seems to envelop Delos, the smallest of all the Cycladic islands. She describes Homer`s account of the god Apollo`s birth which took place there, & how in antiquity it became a major centre of pilgrimage. Today it still attracts many thousands of tourists because of its excavations & its history. She takes the reader on a tour of the isl&, & explains the reason for the Athenian`s annual sacred embassy to Delos.
