The statue, mostly intact, was found under a statue of Amenhotep III in the sprawling Karnak Temple in Luxor, which was a royal city in ancient Egypt.
The statue was found by an archaelogical team from the Johns Hopkins University.
Ti was the first queen of Egypt to have her name appear on official acts alongside that of her husband. She was known for her influence in state affairs in the reigns of both her husband (1417-1379 BC) and of her son, Akhenaton, (1379-1362 BC) during a time of prosperity and power in the 18th dynasty.
Her son is remembered for being the first pharaoh to advocate monotheism.
Ti, of Nubian heritage, is believed to be the grandmother of Tutankhamun, perhaps the most famous ruler of ancient Egypt.
Amenhotep III, who ruled for 38 years, made a basic change in the history of ancient Egypt when he named his wife, Ti, as queen against the tradition that his sister should be queen.
