Although he [Yuya] never reigned as a pharaoh he was the unseen authority behind the thrones of Amenhotep III and Akhenaton. Lately identified as the prototype for the biblical Joseph, he was the richest man in the world after the pharaoh who promoted him. He possessed many illustrious titles. Pharaoh Amenhotep III awarded him the title "Father of a God," a title later passed to his son Aye. Since his daughter Tiye was the mother of Akhenaton, Yuya was the grandfather of the man who would become the most notorious pharaoh in Egypt's long history. His son Aye, the uncle of Akhenaton, would also go on to be a major player in the story of the Atonists. Yuya and his wife Tuya were among the major educators and caretakers of the young Akhenaton. They were Israelites descended from the Hyksos people and were probably of elite rank within that allegedly foreign race. This is probably the reason why Yuya bore the illustrious title "Father to a Pharaoh." It is believed that one of his wives, Asenath, was the daughter of the chief priest of the sun at Heliopolis. Yuya cleverly arranged matters so that his daughter Tiye married Pharaoh Amenhotep III, the son of Tuthmosis IV, who had first honored him. Yuya (Joseph) was descended from Yakobaam/Jacoba/Jacob, an earlier Hyksos pharaoh. In the bible we are toldthat Jacob’s name was changed to Israel, hence the Hyksos people can be known as “Israelites.”If Yuya was indeed the same man as the biblical Joseph it is interesting to note that he served as the chief "tax collector" in charge of the seizure and acquisition of many private estates. The seven years of famine also helped Joseph prosper since, as the bible states, the rich of many lands came to Egypt to purchase grain. More importantly, for our investigations, the bible reveals that Joseph's initial benefactor, Potiphar, was a sun priest of the city of On, or Heliopolis. In Hebrew the name Potiphar means "powerful pharaoh" and in Coptic it means "belonging to the sun." In his fine books author, Ahmed Osman, writes about the effect Yuya's mummified visage had upon him. He relates how his discovery of the connection between Yuya and the biblical Joseph led him to his masterly revisionist readings of the bible and Egyptian history.
Tuya’s mummy had been found with that of her husband Yuya in their small joint tomb (KV. 46) in the Valley of the Kings. Their son-in-law Amenhotep III had honored them with a grand burial, filled the tomb with fabulous gold coffins and death masks, a gilded chariot, inlaid furniture, well-stuffed cushions, a jewel casket and wig box, perfume jars and sandals…Yuya in particular is regarded as the best-preserved Egyptian mummy…Both he and his wife also have bright yellow hair, originally taken as evidence for their supposed foreign origins, equally, perhaps, it may have been the effect of embalming fluids on their otherwise white hair, or evidence of a pale henna rinse
Yuya (Yusuf) was the principle minister for the eighteenth dynasty Pharaoh Tuthmoses IV (c.1413-1405 BC) and for his son Amenhotep III…His tomb was discovered in 1905, along with that of his wife Tuya (the Asenath), and the mummies of Yuya and Tuya are among the very best preserved in the Cairo Museum…Clearly, this couple were of tremendous importance in their day; this becomes obvious from Yuya’s funerary papyrus, which refers to him as ‘The Holy Father of the Lord of the Two Lands’…as does his royal funerary statuette
Tuthmosis IV died relatively young (before 30) and left a very young Amenhotep III (also of mixed blood) in the hands of the priests. Amenhotep III (the prototype for the biblical king Solomon) could only have been between 2 and 12 years of age when he was made pharaoh of Egypt. Because of his young age others stepped in to take control of Egypt from behind the throne. The two most likely candidates were his step-parents - the Israelites - Yuya and Tuya. Scholars recognize their Israelite origins and investigators such as Moustafa Gadalla, Ahmed Osman, and Ralph Ellis, are convinced (as we are) that Yuya was the biblical patriarch Joseph, the previous pharaoh's (Tuthmosis IV) "dream-analyst" and man with the "coat of many colors." Ellis states that this Joseph (Yuya) had been elevated to high command and was not only the second most powerful Egyptian after pharaoh, he was the world's wealthiest human being.
