Debated. The statue is real, but the page does not prove he was a prince.
At Glauberg, in Hesse, Germany, a life-sized sandstone statue of a warrior was found beside a large burial mound. It is 186 centimetres tall. He wears a neck ring, and he has a shield and a short sword. The page dates the statue to about 500 BC. In the grave nearby was a gold neck ring, with weapons and a bronze jug.
The page says experts are not sure the statue is a picture of the man buried there.
