In Greek mythology, a phoenix or phenix (Ancient Greek φοίνιξ phóinīx) is a long-lived bird that is cyclically regenerated or reborn. Associated with the sun, a phoenix obtains new life by arising from the ashes of its predecessor. The phoenix was subsequently adopted as a symbol in Early Christianity.
Classical discourse on the subject of the phoenix points to a potential origin of the phoenix in Ancient Egypt. In the 19th century scholastic suspicions appeared to be confirmed by the discovery that Egyptians in Heliopolis had venerated the benu, a solar bird observed in some respects to be similar to the Greek phoenix. However, the Egyptian sources regarding the benu are often problematic and open to a variety of interpretations. Some of these sources may have been influenced by Greek notions of the phoenix.
