Norse colonists imported timber from North America to Greenland
A microscopic analysis has revealed that Norse colonists imported timber from Northern Europe and North America to Greenland.
Greenland, or Grœnland in Old Norse, was settled by Norwegian and Icelandic explorers in AD 985 or 986. The settlers established two colonies on the southwest coast: The Eastern Settlement or Eystribyggð, in what is now Qaqortoq, and the Western Settlement or Vestribygð, close to present-day Nuuk.
In a study published in the journal Antiquity, archaeologists from the University of Iceland have conducted a wood taxa analysis on pieces of timber found in 11th to 14th century AD Norse farmsteads.
The purpose of the study is to differentiate between native wood, imported wood, and driftwood, revealing that 0.27% of the wood was unambiguous imports, including oak, beech, hemlock and Jack pine. Another 25% of the total wood was either imported or driftwood, including larch, spruce, Scots pine and fir.

Due to the limited resources in Greenland, it has long been suggested that the colonists imported goods and materials such as iron and wood, however, the study has now revealed that these resources were imported from much further than previously thought.
Because hemlock and Jack pine were not present in Northern Europe during the early second millennium AD, the only conclusion to be drawn is that they must have originated in North America. This also confirms the Norse sagas, which describe how the explorers Leifur heppni, Þorleifur karlsefni and Freydís all brought back timber from Vínland to Greenland.
Wood also came from Europe, including the oak, beech and Scots pine. Some of the European wood may have come as ready-made artefacts such as barrel staves, while reused ship timber could have been brought to use in building construction.
According to the researchers: “The presence of North American timber shows that Norse Greenlanders had the means, knowledge and appropriate vessels to cross the Davis Strait to the east coast of North America at least up until the 14th century.”

A study of archaeological sites in Winchester, England, has revealed that red squirrels served as a host for Mycobacterium leprae strains that caused leprosy in people.
Leprosy is one of the oldest recorded diseases in human history and is still prevalent to this day in Asia, Africa, and South America.
It has previously been suggested that the extensive trade of red squirrel fur, greatly valued during medieval times, could have contributed to the leprosy epidemic in medieval Europe.
The results of the study, published in the journal Current Biology, studied 25 human and 12 squirrel samples from two medieval sites in Winchester.
During this period, the city had strong connections to the fur trade and housed the leprosarium, a hospital that treated people with Hansen’s disease (leprosy) caused by Mycobacterium leprae bacteria.
Verena Schuenemann of the University of Basel in Switzerland, said: “With our genetic analysis we were able to identify red squirrels as the first ancient animal host of leprosy.”
The study found that the medieval red squirrel strains were more closely related to human strains in Winchester, rather than to modern squirrel strains from England – suggesting an independent circulation of Mycobacterium leprae strains.
“Our findings highlight the importance of involving archaeological material, in particular animal remains, into studying the long-term zoonotic potential of this disease, as only a direct comparison of ancient human and animal strains allows reconstructions of potential transmission events across time,” says Sarah Inskip of the University of Leicester, UK, a co-author on the study.

Archaeologists from the Uncovering Roman Carlisle project have discovered a rare lump of Tyrian purple at the grounds of the Carlisle Cricket Club in Carlisle, England.
The project is a community supported excavation by Wardell Armstrong, focusing on uncovering a Roman bath house found in 2017.
The bath house is located near the Roman fort of Uxelodunum (meaning “high fort”), also known as Petriana, in the Carlisle district of Stanwix.
Uxelodunum was constructed to control the territories west of present-day Carlisle and an important crossing on the River Eden. The fort was garrisoned by the Ala Petriana, a 1,000-strong cavalry unit, whose members were all granted Roman citizenship for valour on the field.
Previous excavations at the bath house have discovered colossal sandstone heads depicting Roman gods, in addition to engraved gems known as intaglios, figurines, animal bones, and imperial-stamped tiles.
During the latest season of excavations, archaeologists found a mysterious lump of a soft purple substance. The substance was tested by researchers from Newcastle University, revealing that it contained levels of Bromine and beeswax.
According to the researchers, the substance is Tyrian purple, a coloured dye associated with the Imperial Court in the Roman Empire. Tyrian purple is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name Murex.
Frank Giecco, Technical Director at Wardell Armstrong, said: “For millennia, Tyrian Purple was the world’s most expensive and sought after colour. It’s presence in Carlisle combined with other evidence from the excavation all strengthens the hypothesis that the building was in some way associated with the Imperial Court of the Emperor Septimius Severus which was located in York and possibly relates to an Imperial visit to Carlisle.”
“It’s the only example we know of in Northern Europe – possibly the only example of a solid sample of the pigment in the form of unused paint pigment anywhere in the Roman Empire. Examples have been found of it in wall paintings (like in Pompeii) and some high status painted coffins from the Roman province of Egypt,” said Giecco.
