Building a Viking boat today

In September 2013, the National Maritime Museum Cornwall was approached by the British Museum and asked if we would produce something Viking to be filmed for their Vikings Live cinema broadcast, after seeing the Bronze Age boat replica that we had built and launched in March 2013.

Of course, we said yes. After plenty of chats with Gareth Williams, the curator of the BP exhibition Vikings: life and legend and Patricia Wheatley, Executive Producer of Vikings Live, our boat restoration team started to build the stem section of a Viking-style boat, to be constructed using traditional methods.

I was to manage the project, with my team of boat crew volunteers and boat-builder Brian Cumby, who had built the Bronze Age boat. The stem section was approximately sixteen feet long, eight feet beam (width) and about 12 feet at its highest, to be surmounted with a Viking dragon’s head. The section is equivalent to about 25% of a boat that we are planning to build next year as a feature of our Viking Voyagers exhibition in 2015.

Having assembled the team, I had to source the materials. There was no time to make nails, so they came off the shelf as galvanised Scandinavian boat nails with square roves made by our local blacksmith. The keel and stem post were to be oak, and we decided to plank in Cornish larch, not always durable for boats, but good for this project. Our friends at Tregothnan Estate, not far from us in Falmouth (also known for its excellent tea plantation) provided all of our needs, including a lot of crooks or timber turns, used for making frames to brace the planking.

Brian set up the keel and the rabbet (the groove or rebate that takes the first planks) was cut. A joint was then cut for joining the stem post to the keel to create the backbone of the boat ready for planking. Brian and his team of volunteers then built up the layers of planking by riveting overlapped planks one on to the other. This method is called clinker in Europe and Scandinavia, and lapstrake in the America and Canada. We planned on seven planks to each side, each about one inch thick and twelve inches wide. The larch planks had to be steamed in a long steam box to make the wood malleable enough to fit to the keel and stem rabbet.

To get the shape of a Viking boat we built moulds or section shapes that acted as guides. It is thought that the Vikings would have set up an overhead strong back supported by an A-frame, in order to brace the struts or shores to brace the planking. They are also likely to have heated stones to make the planks malleable as an alternative to steaming.

The crooks and turns were shaped and fashioned into frames, floors and knees (boatbuilding terms to describe brackets and braces that were fitted to the planking to add cross-sectional strength). Finally the thwarts or cross-section benches were fitted. All were fastened with nails or trenails (pegs of oak or tree nails that would swell and tighten when wet, sometimes with a small wedge driven down the grain to further expand and tighten).

Viking ship construction developed boats that were light, strong, but flexible so that they worked well with the stresses of the sea. They were also shallow draught, which meant that they could still move through shallower river and estuary waters. Climbing in and out was also easier, as speed and surprise were a feature of many Viking visits!

While all of this frantic construction was going on, our woodcarver Rob (a National Maritime Museum Cornwall volunteer) began to work on the stem head. His brief was to make something that would frighten the natives. With help from Patricia from the British Museum, he researched some designs, and decided to use a Viking pin that was being displayed in the exhibition as his inspiration. The head was to be detachable, following the Vikings practice – apparently the raiding boat would remove the stem head on return to its home port so as not to bring bad spirits back with them or scare those on dry land.

The project has enabled our team to get in a ‘Viking’ mind-set , as we will not only be building a replica of a 57-foot Roskilde boat, but likely some very Viking stage sets for the National Maritime Museum Cornwall Viking Voyagers exhibition, supported by the British Museum.

This week we’re highlighting the work of our #AfricanRockArt image project. The project team are now in the third year of cataloguing, and have uploaded around 19,000 digital photographs of rock art from all over #Africa to the Museum’s collection online database.

This photograph shows an engraving of a large, almost life-sized elephant, found on the Messak Plateau in #Libya. This region is home to tens of thousands of depictions, and is best known for larger-than-life-size engravings of animals such as elephants, rhino and a now extinct species of buffalo. This work of rock art most likely comes from the Early Hunter Period and could be up to 12,000 years old.

Follow the link in our bio and explore 30,000 years of stunning rock art from Africa. Watch the incredible discovery of this colossal statue, submerged under the sea of thousands of years. This colossal 5.4-metre statue of Hapy was discovered underwater in what was the thriving and cosmopolitan seaport of Thonis-Heracleion. It once stood in front of a temple and would have been an impressive sight for traders and visitors arriving from the Mediterranean.

Come face to face with the ancient Egyptian god Hapy for yourself in our‪ #SunkenCities exhibition, until 27 November 2016.

The discovery of this stela, which once stood at the entrance of the main entry port into ancient Egypt, was an extraordinary moment. Its inscription detailing taxes helped solve a 2,000-year-old mystery!

This magnificent monument was crucial to revealing that Thonis (in Egyptian) and Heracleion (in Greek) were in fact the same city. The decree was issued by the pharaoh Nectanebo I, regarding the taxation of goods passing through the cities of Thonis and Naukratis, and it originally stood in the Temple of Amun-Gereb. The inscription states that this slab stood at the mouth of the ‘Sea of the Greeks’ (the Mediterranean) in Thonis.

A bilingual decree found in 1881 refers in its Greek inscription to ‘the Temple of Heracleion’ and in hieroglyphs to ‘the Temple of Amun-Gereb’. Together these objects revealed that Thonis and Heracleion were the same place.

For centuries nobody suspected that the #SunkenCities of Thonis-Heracleion and Canopus lay beneath the sea. Recorded in ancient writings and Greek mythology, the ancient Egyptian cities were believed to be lost.

Over the last 20 years, world-renowned archaeologist Franck Goddio and his team have excavated spectacular underwater discoveries using the latest technologies. The amazing rediscovery of these lost cities is transforming our understanding of the deep connections between the great ancient civilisations of Egypt and Greece.

#archaeology #diving #ancientEgypt This week we’re highlighting some of the incredible clocks and watches on display in the Museum. Mechanical clocks first appeared in Europe at some time between 1200 and 1300. Their introduction coincided with a growing need to regulate the times of Christian prayer in the monasteries. Telling the time with a sundial was especially difficult in western Europe with its unreliable weather. From the end of the 13th century, clocks were being installed in cathedrals, abbeys and churches all around Europe.

The design of turret clocks (public clocks) changed little over the following three centuries and this particular example, made around 1600, has similar characteristics to clocks made for churches in the medieval period. The maker of this clock was Leonard Tenant, one of the most prolific makers of church clocks in the first half of the 17th century. The clock was installed in Cassiobury Park, a country house near Watford.

See this incredible clock in Rooms 38-39 
#clocks #watches #horology When clocks and watches were invented around 1200, sound, touch and illumination were all used to read the time in darkness. This was significant because electric lighting did not become widespread until the 20th century.

This photograph shows a detail from a night clock by Pietro Tomasso Campani made in 1683. When it is dark, light from an oil lamp behind the dial shines through the cut-out Roman numerals enabling the time to be read. Each hour, the numeral for that hour moves round the dial. This ‘wandering hour’ dial was invented by the makers of this clock.

You can see this clock in a new display of clocks and watches in our Members’ Room, just one of the many benefits of becoming a Member of the British Museum. Find out more about Membership at www.britishmuseum.org/membership
