Archaeologists in Denmark have found a small knife inscribed with runic letters dating back almost 2,000 years, the oldest trace of writing found in the country, the Museum Odense said on Tuesday. Runic letters, called runes, are the oldest alphabet known in Scandinavia.

They were in use from the first or second century AD in northern Europe until being replaced by the Latin alphabet amid christianisation in the 10th century.

“The knife itself is not remarkable but on the blade there are five runes — which is extraordinary in itself — but the age of the runes is even more extraordinary because they actually are the oldest we have from Denmark,” archaeologist Jakob Bonde told AFP. “We don’t have any writing before this.”
