Opet Festival [SEP] Introduction
The Opet Festival (the Beautiful Feast of Opet/"heb nefer en Ipet") was an annual Ancient Egyptian Festival celebrated in Thebes (Luxor), especially in the New Kingdom and later periods, during the second month of the season of Akhet, the flooding of the Nile. The festival was celebrated to promote the Fertility of Amun-Re and the Pharaoh, who was also believed to be the spiritual offspring of Amun-Re; the Son/Daughter of Amun-Re. John Darnell argues that “Opet began on II Akhet 15 under Thutmose III and lasted 11 days (Sethe 1907: 824, line 10); by the beginning of the reign of Ramesses III, the festival stretched over 24 days” (Darnell, 2010).
