Dr. Zahi Hawass, general director of the Supreme Council on Antiquities in Egypt, accepted the remains Friday as a gift from the Michael C. Carlos Museum at Atlanta's Emory University, which bought the mummy in 1999 from a Niagara Falls freak-show collection, the New York Times said.
"This is the only king outside of Egypt," Hawass said.
Rameses was pharaoh of Egypt from 1293 B.C. to 1291 B.C.
Only a few royals from that era were missing. Curators believed the mummy had been bought from 19th-century dealers who had looted a cache of pharaohs that included a coffin for Rameses I. It was empty.
Hawass has made it his mission to reclaim those ancient Egyptian artifacts that he said "have no parallel." The mummy will make a stop at the Cairo Museum before heading to its permanent home at the Luxor Museum.
