This is the account given by a poet and the historian Paulus Fabius in the year AD 34.
"Most beings spring from other individuals; but there is a certain kind which reproduces itself. The Assyrians call it the Phoenix. It does not live on fruit or flowers, but on frankincense and odoriferous gums. When it has lived 500 years, it builds itself a nest in the branches of an oak, or on the top of a palm tree. In this it collects cinnamon, and spikenard, and myrrh, and of these materials builds a pile on which it deposits itself, and dying, breathes out its last breath amidst odors. From the body of the parent bird, a young Phoenix issues forth, destined to live as long a life as its predecessor. When this has grown up and gained sufficient strength, it lifts its nest from the tree (its own craddle and its parent's sepulchre), and carries it to the city of Heliopolis (in Egypt), and deposits it in the temple of the Sun."
"The first care of the young bird as soon as fledged, and able to trust its wings, is to perform the obsequies of his father. But this duty is not undertaken rashly. He collects a quantity of myrrh, and do try his strength makes frequent excursions with a load on his back. When he has gained sufficient confidence in his own vigor, he takes up the body of his father and flies with it to the alter of the Sun, where he leaves it to be consumed in flames of fragrance."
