A Danish amateur archeologist found 22 gold objects with sixth-century symbols, possibly yielding new details about pre-Viking people in the country, the museum that will house the treasure said Monday.

Some of the objects have runic motifs and inscriptions that may refer to the rulers of the time but also recall Norse mythology, Mads Ravn, director of research at the Vejle museums in western Denmark, told Agence France-Presse (AFP).

"It is the symbols on the items that make them unique, more than the quantity found," according to Ravn, who said the treasure weighed about 1 kilogram (2.2 pounds).

One piece even refers to the Roman Emperor Constantine from the early fourth century, Ravn said.

"The find consists of a lot of gold items, including a medallion the size of a saucer," Ravn added.

According to initial examinations, the treasure could have been buried as an offering to the gods at a chaotic time when the climate in northern Europe dramatically turned colder after a volcanic eruption in Iceland in 536 sent ash clouds into the sky.

"They have many symbols, some of which have not been seen before, which will enable us to expand our knowledge of the people of this period," he said.

The treasure was found near Jelling in southwestern Denmark, which historians say became a cradle for kings of the Viking age, which lasted between the eighth and 12th centuries.

The treasure will be on display at the museum in Vejle starting in February 2022.

The amateur archeologist using a metal detector actually found the treasure about six months ago, but the news was only disclosed recently.
