during his reign. Reign length Approximately 837 BC, Osorkon II died and he was buried in Tomb NRT I at Tanis. Currently, he is believed to have reigned for more than 30 years, rather than just 25 years as had been interpreted earlier. The celebration of his first Sed Jubilee previously was thought to have occurred in his Year 22, but the Heb Sed date in his Great Temple of Bubastis is damaged and also may be read as Year 30, as Edward Wente notes. The fact that this king's own grandson, Takelot F, served him as High Priest of Amun at Thebes–as the inscribed walls of Temple J prove – supports the hypothesis of a longer reign for Osorkon II. Recently, it has been demonstrated that Nile Level Text 14 (dated to Year 29 of an Usimare Setepenamun) belongs to Osorkon II on palaeographical grounds. This finding suggests that Osorkon II likely did celebrate his first Heb Sed in his Year 30 as was traditionally the case with other Libyan era kings, such as Shoshenq III and Shoshenq V. In addition, a Year 22 Stela from his reign preserves no mention of any Heb Sed celebrations in that year, as would be expected (see Von Beckerath, 'infra'). While Osorkon II's precise reign length is unknown, some Egyptologists, such as Jürgen von Beckerath – in his 1997 book Chronology of the Egyptian Pharaohs – and Aidan Dodson have suggested a range of between 38 and 39 years. However, these much higher figures are not verified by the current monumental evidence. Gerard Broekman gives Osorkon II a slightly shorter reign of 34 years. English Egyptologist Kenneth Kitchen, in a 2006 "Agypten und Levante" article, now accepts that if Nile Level Text 14 is correctly attributed to Year 29 of Osorkon II, then the reference to Osorkon's Sed Festival jubilee should be amended from Year 22 to Year 30. Kitchen suggests that Osorkon II would have died shortly afterward, in his Year 31. Marriages and children Osorkon II is known to have had at least four wives: Queen Karomama is the best known of Osorkon's wives. Karomama was the mother of at least two sons and three daughters: Isetemkheb is known to be the mother of a daughter named, Tjesbastperu, who was married to the High Priest of Ptah Takelot B. Djedmutesakh IV was the mother of the High Priest of Amun
