First Epistle to the Corinthians

Let us consider that remarkable sign [of the resurrection] that occurs in Eastern lands, specifically in Arabia and the surrounding countries. There is a certain bird called a phoenix. It is the only one of its kind and lives for five hundred years. When the time of its death approaches, it builds itself a nest of frankincense, myrrh, and other spices. When the time is complete, it enters the nest and dies. As the flesh decays, a certain type of worm is produced, which, nourished by the juices of the dead bird, develops feathers. Then, when it has gained strength, it takes up the nest containing the bones of its parent and carries them from the land of Arabia to Egypt, to the city called Heliopolis. In broad daylight, flying in the sight of all people, it places the bones on the altar of the sun and, having done this, quickly returns to its previous home. The priests then check the records of the dates and find that it has returned exactly when the five hundredth year was completed.
