New analysis of the dagger buried with King Tut confirms that the weapon was made from an iron meteorite. They used X-ray fluorescence spectrometry to study the dagger, found on Tut's mummified body by Howard Carter in 1925. Daniela Comelli of Milan Polytechnic's department of physics and her colleagues have even identified the most likely meteorite used to forge the dagger.
"We took into consideration all meteorites found within an area of 2,000 km in radius centered in the Red Sea, and we ended up with 20 iron meteorites," Comelli told Space.com. "Only one, named Kharga, turned out to have nickel and cobalt contents which are possibly consistent with the composition of the blade."
The study shows the ancient Egyptians attributed great value to meteoritic iron for the production of precious objects, possibly perceiving those chunks of iron falling from the sky as a divine message.
The most ancient Egyptian iron artifacts, nine small beads excavated from a cemetery along the west bank of the Nile tomb in Gerzeh and dated about 3200 BC, are also made from meteoritic iron hammered into thin sheets.
"It would be very interesting to analyze more pre-Iron Age artifacts, such as other iron objects found in King Tut's tomb. We could gain precious insights into metal working technologies in ancient Egypt and the Mediterranean," Comelli said.
