Iron dagger found in King Tut's tomb is made from a meteorite




An iron dagger found in King Tut’s tomb in Egypt in the 1920s was long thought to be made from a meteorite – and now it’s confirmed. The article published in the Meteoritics & Planetary Science journal also suggests that the Egyptians knew where the metal came from, referring to it as ‘iron of the sky.’

Scientists previously claimed that an iron dagger, and a gold blade, in King Tutankhamun’s tomb may have come from meteorites. Researchers from Italy and the Egyptian Museum of Cairo have used x-ray fluorescence spectrometry to accurately determine that the dagger consisted of iron, nickel, and cobalt that matches the components of known meteors. Therefore they can confirm that the iron dagger found in King Tut’s tomb is of meteoritic origin.

The researchers say that this ‘suggests that the ancient Egyptians, in the wake of other ancient people of the Mediterranean area, were aware that these rare chunks of iron fell from the sky already in the 13th century BCE, anticipating Western culture by more than two millennia.’ It also adds more light on the spread of iron metallurgy in different early civilizations.

The sporadic use of iron has been reported in the Eastern Mediterranean region from the late Neolithic period to the Bronze Age. Despite the rare existence of smelted iron, it was generally assumed that early iron objects were produced from meteoritic iron. Nevertheless the methods of working with the metal and its use were contentious due to the lack of evidence.

Since its discovery in 1925, the meteoritic origin of the iron dagger blade from the sarcophagus of the ancient Egyptian King Tutankhamun (14th century BCE) has been the subject of debate. Previous analyses produced controversial results.

The Italian researchers show that the composition of the blade is iron with 11% nickel and 1% cobalt. It was accurately determined using portable x-ray flourescence spectrometry. In agreement with recent results of the metallographic analysis of ancient iron artefacts from Gerzeh, this study confirms that ancient Egyptians attributed great value to meteoritic iron for the production of precious objects. Moreover, the high manufacturing quality of Tutankhamun’s dagger blade, in comparison with other simple-shaped meteoritic iron artefacts, suggests a significant mastery of ironworking in Tutankhamun’s time.

The team of researchers from the Milan Polytechnic, the University of Pisa, the Egyptian Museum of Cairo, XGLab in Milan, the Fayooum University, the Institute of Photography and Nanotechnology in Milan, and the Torino Polytechnic were funded by the Ministry of Foreign Affairs and International Cooperation, and the Egyptian Ministry of Scientific Research.

2016 update on Rike Park, Tbilisi: from construction to busy park

From a flat patch of uninteresting dirt, Rike Park in Tbilisi, Georgia, has transformed in four years (from 2014-2016) into a busy park full of trees, flower beds, sculptures, fountains, and events. Rike (Rikhe) Park is on the left bank of the Mt’k’vari River (the Kura River) near the Old City of Tbilisi. The Peace Bridge links the right bank to Rike Park. Rike Park is below the hillside Presidential Palace and, via cable car, it is the starting point for the ride to Sololaki Ridge (with the Narikala Fortress and the Mother of Georgia statue). The glass box-shaped cable car terminus was opened on 23 June 2012, and since then the park has continually developed into a ‘people’s park’ where people can walk around, eat at the nearby restaurants, sit next to the statue of American president Ronald Reagan, climb the steps to Avlabari district, and access the sights of Meidan Square, the Peace Bridge, the Metekhi Church, the Old City, the waterfall, the sulphur baths, and t...

Hop on hop off bus tourism comes to Tbilisi, Georgia

City Sightseeing buses have arrived in Tbilisi. The iconic red double-decker buses, a feature of many cities around the world since the company was established in Seville, Spain in 1999, is now in six continents and almost 100 cities. The company established its Tbilisi business in November 2013, with its operations commencing in February 2014. The 90-minute tour stops at 11 major locations in Tbilisi (with 2 to 5 minute waiting times at each location): the Old City (where it commences), Freedom Square, Rose Revolution Square, Marjanishvili Square, the Dry Bridge, Konka, Avlabari, Metekhi, Akhundov Museum, the Sulfur Baths, and European Square. Passengers can hop off at any stop and see the sights, hopping back onto the next bus at any time.
