Dagger found in Tutankhamun's tomb was made with meteorite iron

Dagger found in Tutankhamun's tomb was made with meteorite ironA dagger entombed with King Tutankhamun was made with iron from a meteorite, a new analysis on the metal composition shows.

In 1925, archaeologist Howard Carter found two daggers, one iron and one with a blade of gold, within the wrapping of the teenage king, who was mummified more than 3,300 years ago. The iron blade, which had a gold handle, rock crystal pommel and lily and jackal-decorated sheath, has puzzled researchers in the decades since Carter’s discovery: ironwork was rare in ancient Egypt, and the dagger’s metal had not rusted.

Italian and Egyptian researchers analysed the metal with an x-ray fluorescence spectrometer to determine its chemical composition, and found its high nickel content, along with its levels of cobalt, “strongly suggests an extraterrestrial origin”. They compared the composition to known meteorites within 2,000km around the Red Sea coast of Egypt, and found similar levels in one meteorite.

That meteorite, named Kharga, was found 150 miles (240km) west of Alexandria, at the seaport city of Mersa Matruh, which in the age of Alexander the Great – the fourth century BC – was known as Amunia.

Although people have worked with copper, bronze and gold since 4,000BC, ironwork came much later, and was rare in ancient Egypt. In 2013, nine blackened iron beads, excavated from a cemetery near the Nile in northern Egypt, were found to have been beaten out of meteorite fragments, and also a nickel-iron alloy. The beads are far older than the young pharaoh, dating to 3,200BC.

“As the only two valuable iron artifacts from ancient Egypt so far accurately analysed are of meteoritic origin,” the team that studied the knife wrote, “we suggest that ancient Egyptians attributed great value to meteoritic iron for the production of fine ornamental or ceremonial objects”.
