41 sealings showing the cartouche of the Hyksos ruler Khyan together with 9 sealings naming the 13th dynasty king Sobekhotep IV. As Moeller and Marouard write: "These finds come from a secure and sealed archaeological context and open up new questions about the cultural and chronological evolution of the late Middle Kingdom and early Second Intermediate Period." These conclusions are rejected by Robert Porter who argues that Khyan ruled much later than Sobekhotep IV and that the seals of a pharaoh were used even long after his death. Another option he proposed is that Sobekhotep IV reigned much later than previously thought. Nearly all carbon-14 analyses of materials related to the Second Intermediate Period yield dates on average 120 years earlier than was expected from the prevailing chronological reconstruction of the 15th Dynasty. While the debate is ongoing, Egyptologists have acknowledged the validity of these observations and that they indicate some major issue with the consensus reached hitherto. Khyan's rule is no longer dated with any accuracy. The Egyptologist David Aston has showed available evidence is compatible with Khyan ruling anywhere between 1700 BC and 1580 BC, with the former his preferred scenario. The possibility that one or more kings reigned between him and Apophis is now the dominant hypothesis. A stela of Khyan mentioning a king's son was also discovered at Avaris. Manfred Bietak observed that: "a stela set up in Avaris contains the nomen and prenomen of Khyan and a now lost dedication (presumably to Seth, Lord of Avaris) below which are inscribed the title and name of the Eldest King's Son Yanassi." The Danish Egyptologist Kim Ryholt, who published an extensive catalogue of the monuments of all the numerous pharaohs of the Second Intermediate Period, notes an important personal detail regarding this king's family; Ryholt writes that the association of Khyan with those of his eldest son upon this stela suggests that Yanassi in fact was his designated successor, as also implied by his title." Ryholt speculates that Manetho might have mentioned Yanassi in a now lost passage and that one possible explanation of the name Iannas used by Josephus for Khyan is a misquotation of such a passage in which the son's name was extracted instead of the father's. Origin of Khyan's name Ryholt notes that the name, Khyan, generally has been "interpreted as Amorite Hayanu (reading h-ya-a-n) which the Egyptian form represents perfectly, and this
