A Project on the Low German merchants’ trade from Bremen and Hamburg with the North Atlantic islands is not complete without the vessels that made trade across the ocean possible. The written sources tell us that many German ships were lost along the coast of Iceland, but until today, not a single mentioned shipwreck was found. This is not surprising, given the circumstance that underwater archaeology in Iceland is not even twenty years old.
Some facts about finding shipwrecks
The saying “Searching for a needle in a haystack” is fitting pretty well to the search for shipwrecks mentioned in historical documents, considering the abilities to determine a ship’s position in the past and the fact that 71 % of Earth’s surface is covered by water. Even today, many ships vanish without a trace. On top of that, the number of archaeologists looking for certain shipwrecks is extremely low. Therefore, most shipwrecks are found by accident and they remain more or less anonymous.
However, technology has improved and the potential for finding shipwrecks is much higher today than in the past. A number of devices can be used and combined for surveying the sea floor. A common combination is a side-scan sonar and a number of magnetometers, but this is still no guarantee for finding wrecks. When a ship is too decayed, or has settled into the sediment, the sound-rays of the side-scan sonar will not be able to produce a recognisable image. Moreover, magnetometers will not detect anomalies from the earth’s magnetic field when there is not enough metal on board the ship. Especially for medieval ships and early modern merchant vessels without guns, this can easily be the case. A sediment sonar could be a solution, which measures changes of density in the sediment with sound signals. The disadvantage is that waterlogged wood has the same density as waterlogged sediment. If a shipwreck has no denser cargo or ballast on board, the sonar will not detect density changes. Therefore such ships will remain hidden, even if an area is surveyed. Divers might be suggested as a final solution but a diver’s operating range is very limited, as he/she depends on depth, weather conditions, visibility and air supply.
The fact is that archaeologists rely in most cases on coincidences, which is how most of the known shipwrecks were found. The reason for this is that many other professions like builders, fishermen, geologists etc. spend much more time working on the sea floor than archaeologists, and sometimes stumble upon a wreck. One famous example for this is for example the “Bremen Cog” in the German Maritime Museum in Bremerhaven. A suction-excavator operator found it in the river Weser close to Bremen, when he was working on an extension of the riverbed. It became one of the most important finds in ship archaeology. Over the past decades, since underwater became an area of archaeological interest, hundreds of shipwrecks have been registered by the heritage departments of the German federal states but only a few of them could be identified by historical documents.
When we approach the shipwrecks from the historical documents, we have to realize that mentioned positions for lost ships are most of the time very vague. This situation can extend the search area dramatically without even knowing if the wrecks still exist as a coherent site. The conditions of the natural environment are vital to the survival of remains. Rugged coastlines, strong currents, micro-organisms, the chemical consistence of the water and the like can severely contribute to the decay of organic matter, metals and even certain types of stone. In the Mediterranean Sea, for example, ship hulls will not survive for a long time above the sea floor due to temperature, salinity and micro-organisms. Iron will soon vanish by the reaction with salt and oxygen and even marble and copper-alloys will decay. The opposite situation can be found in the Northern Baltic or the Sea Black Sea, for example. The Northern Baltic is deep, has a very low salt content and is cold. This prevents wood-decaying organisms to multiply and destruction from anchors or looting divers. The Black Sea water, on the other hand, has hardly any oxygen in a certain depth, which almost freezes time on the sea floor.
In addition, the circumstances of the sinking in connection to the natural environment play an important role. A German ship in Spanish service in 1588, the Gran Grifon, hardly left any structural remains. Another extreme example is the destruction of a united navy fleet of Lübeck and Danish ships during the Nordic Seven Years War on the west coast of Gotland in 1566. Out of thirty-seven ships, fifteen were lost and 6000 to 8000 sailors lost their lives in the so-called Visby-Disaster. Intensive archaeological diving surveys for several years could not reveal any wreck site. The ships literally vanished, most likely because they disintegrated in the storm on the rough sea floor and their remains were thrown up on the beach.
These examples shows us that a sunken ship mentioned in the historical documents does not always leave a proper wreck site. Sometimes scattered debris spread over square kilometres of sea floor can be all that is left of a ship.
The missing wrecks of Iceland
In theory, Iceland has a high potential for finding shipwrecks. Since the late 9th century, humans settle here and they had no other way than to cross the rough North Atlantic Ocean and make landfall on a rugged coast. Many ships, Norwegian, Danish, English, Low German and Dutch, evidently got lost on their route between continental Europe and Iceland. A considerable number of these found their end on the coast of Iceland, as we can read in the historical documents. Ragnar Edvardson has calculated a number of about 450 shipwrecks in Iceland, from the period from 1100 to 1900, most of which foundered on the West coast. Until today, no wreck from the period of the Low German trade has been found. The oldest ship found in Iceland is currently a Dutch merchantman, which sank in the harbour at Flatey in Breiðafjörður in 1659, and is currently under investigation by Kevin Martin. The scarcity of known shipwrecks in Iceland is not necessarily because they vanished completely, but because maritime archaeology is a very young discipline in this country and started only with sporadic projects from 1993 onwards. The relatively few inhabitants of Iceland also reduce the possibility of coincidental discoveries of wrecks due to the lack of building activities.
Vive la Coïncidence!
However, coincidences happen – even in Iceland. In 1998, an excavator hit timbers while digging a cable trench near Búðir on the Snæfellsnes peninsula in Western Iceland. They turned out to be fragments of a ship that was buried under the sand of an estuary. Some timbers and ballast stones were recovered by archaeologist Björn Stefánsson, and brought to the National Museum of Iceland in Reykjavik, were they were documented and put in storage. None of the recovered timbers was suitable for dendrochronological dating, but the ballast included stones that can possibly originate in Norway, Britain or Greenland. However, this does not give any indication were the ship was coming from, because ballast was taken from board and loaded in all harbours depending on the cargo and to adjust the angle of the ship in the water, to trim the ship. The recovered timbers give the impression of an old carvel-built ship. The material seems not to be of the finest quality, but this is hard to judge from only a handful of timbers. A promising fact is that Búðir was an important trading centre in Iceland for at least 200 years. It was already visited by Bremen merchants in the late 16th century, who called it “Bodenstede”. For a long time it was the main trading site for the Snæfellsness Peninsula, called first by cargo ships of the Low German merchants and later by Danish and Dutch ships. It was abandoned as a trading post in 1787.
For this reason, we have written sources on the activities on this site including the loss of several ships during these 200 years. The problem for the identification of the accidental found ship is the fact that there was not only one ship lost near the site. We know at least about eleven ships that are reported to have been lost at Búðir and its harbour Búðavik. Of those eleven ships, one was from Bremen. It belonged to the merchant Vasmer Bake and sank in or close to the harbour of Bodenstede in 1587. This was reported by Carsten Bake, his son, who himself was involved in the Iceland trade. In 1607, a Danish ship wrecked at Búðir. For 1666, another ship sank west of Búðir. More ships sank in this area in 1724, 1728 (Danish) and 1754, and lastly, Bjarni Sívertsen’s cutter, which got lost here in 1812.
Certainly, it is possible that the ship found in 1998 is Vasmer Bake’s lost vessel from 1587, but the timbers cannot give us any more detailed information. All we can say today about the few recovered timbers is that there are five floor timbers and two fragments with an unknown function. The floor timbers indicate that the cable trench hit the wreck most likely in the bow section, leaving most of the buried remains uncovered. Each plank was attached to each frame with at least two tree nails, and each frame was connected to the keel with one or two tree nails. The dimensions of the floor timbers vary a lot, from flat and wide to high and narrow. This might be an indication that whoever built the ship faced either a shortage of crooked compass timbers, or the building did not rely on an even framing in a shell based building method, or both. However, it can also not be excluded that we face the remains of Bjarni Sívertsen’s cutter from 1812. Only future investigations might give us an answer.

Bart Holterman presentated the project and his own research on August 5 in Haus der Wissenschaft in Bremen. Matthias Holthaus was there as well and wrote the following article about it in the Weser Kurier of August 21, which gives a nice overview of the situation German merchants had to deal with when trading in the North Atlantic in the late Middle Ages (in German).

Keeping the Faroese bishop warm – how a tiled stove tells the story of the Reformation in the Faroes
Natascha Mehler, 16 August 2017
with Torbjörn Brorsson, Martina Wegner and Símun V. Arge
In 1557 the Reformation in the Faroes came to an end when the Faroese bishopric at Kirkjubøur was abolished and its properties confiscated by Christian III of Denmark. This was the result of a process which started in 1539 when Amund Olafson, the last Catholic bishop, was replaced by Jens Gregersen Riber, the first Lutheran bishop of the Faroes. Jens Riber stayed at Kirkjubøur until 1557 when he left to take on a new position in Stavanger. We know very little about the lives of these two bishops. However, during archaeological excavations conducted in 1955 at the site of the former episcopal residence, the remains of a tiled stove dating to the early and mid-16th century came to light which add knowledge about the daily life at Kirkjubøur.
The tile fragments were now, more than 60 years after their discovery, analyzed as part of this research project. Tiled stoves were a luxurious rarity in the North Atlantic islands. In Iceland, for example, 16th-century tiled stoves are only known from the two bishoprics at Skálholt and Hólar, the Danish residence at Bessastaðir and from the monastery at Viðey. The Kirkjubøur fragments are the only remains of a tiled stove in the Faroes. In Denmark or Northern Germany, however, tiled stoves were rather common in burgher households and those of the nobility.
19 stove tile fragments were found at Kirkjubøur, all made from red clays, moulded with relief decoration and applied with a white slip and green lead glaze. Varying fabric and decoration indicates that the tiles are the products from at least two different workshops. This means that either the tiles of the former stove were exchanged during its lifetime, or the stove was made from tiles from different workshops. The latter interpretation would be rather unusual in a continental context but all known early modern tiled stoves from Iceland were made of tiles from different workshops because access, import and maintenance were very difficult.
The images on the Kirkjubøur tiles mirror the struggles of the introduction of the Reformation in the Faroes. All tiles show Christian or biblical motifs and themes, but while one of the identified motifs displays catholic imagery, others are clearly reformist in meaning. In many Northern European households such stove tiles decorated with Lutheran imagery were indeed used as a medium to express the Lutheran confession.
One stove tile fragment shows a female figure with a cross in her left hand. A letter “S” is preserved, suggesting that this is a female saint such as Helena. If this interpretation holds true it would be a tile with purely Catholic imagery. The best preserved stove tile shows a bearded man in profile and the words [S]ANT PAVLO APOSTOLVS. Although this is a depiction of yet another saint – and thus rather Catholic in meaning – the letters of Paul the Apostle were often invoked by reformist theologians of Wittenberg. All other identified motifs were popular amongst supporters of Lutheranism. One fragment shows the lower body part of a female figure with a man’s head next to it. This is clearly a depiction of Judith with the head of Holofernes in her hand, a widespread stove tile motif in Lutheran contexts. And two identical tiles show the ascension of Jesus and parts of the creed of the Lutheran catechism. The surviving text reads 6 ER IST AVGEFARE[N] GEN HIMEL SITZET ZVR RECHTEN GOTES DES ALMECHTIGEN VATERS (transl. “he has ascended into heaven, and is seated at the right hand of the Father”). The letter 6 indicates that this is the sixth stove tile in a series.
Eight fragments of these stove tiles were selected for analysis by Inductively Coupled Plasma Atomic Mass Spectrometry (ICP-MA/ES), a standard method in ceramic analysis, carried out by Torbjörn Brorsson (Kontoret för Keramiska Studier). The main goal of the analysis was to determine the chemical composition of the various fabrics, with the aim to identify the workshops which produced these tiles. The results show that the tile with Paul the Apostle was made in Lübeck, and the tile with Judith and Holofernes, as well as the tile with the creed of the Lutheran catechism, in the surroundings of Lübeck. The tile with the female saint was made in the area between Lübeck and Bremen, which also includes Hamburg. This is no surprise; Northern German potters were the leading craftsmen to supply the Northern European market with stove tiles at that time.
The stove tiles were imported to the Faroes during the period when the Faroes were licensed to Hamburg citizen Thomas Koppen, between 1529 and 1553. Thomas Koppen was Oberalter of the churches in Hamburg and therefore an important figure in the process of the Reformation there. Maybe Koppen’s merchants (very likely he never visited the Faroe Islands himself) had brought the tiles from Lübeck via Hamburg to the Faroes. It is also very likely that Norwegian merchants from Bergen brought the tiles to the Faroes. The islands were closely connected to Bergen, with many ships travelling between the harbours of Tórshavn and Bergen. Lübeck merchants held a very important position in Bergen at that time and the tiles could have been brought from Lübeck first to Bergen and then went further to the Faroes.
The story that the tile finds suggest is such: a tiled stove was first erected at Kirkjubøur during the office of the Catholic bishop Amund Olafson, and fitted with tiles such as the one with the female saint. When Jens Riber took over as first Lutheran bishop in 1539 he bought new tiles from a different workshop and exchanged the purely Catholic images on his stove with motifs of the new faith. Only then could he enjoy the comforting warmth effusing from his stove without being agonized by the troubling sight of Catholic images.

In the 15th to 17th centuries, the North Atlantic Islands of Shetland, Faroe and Iceland were frequently visited by Hanseatic merchants, who usually made one voyage each year. The trading season started roughly in April and finished in August/September and because of its regular character, we have much information about the number of Hanseatic ships sailing North each year.
In the middle of the 16th century, on average 5 ships per year from Bremen and 1 or 2 ships from Hamburg travelled to Shetland. Contemporary sources from 1560 speak of a minimum of 7 ships from Bremen and Hamburg in Shetland harbours. In Iceland, the numbers were even higher. For example in 1585, 14 ships from Hamburg alone and 8 ships from Bremen, Lübeck and Danzig reached Icelandic harbours, and in 1591 as many as 21 ships from Hamburg arrived in Iceland. In spite of these high numbers of voyages and some documented losses of Hanseatic ships – there are at least 10 known losses around Shetland and 3 losses around Iceland – no wrecks or remains of Hanseatic trading ships in the North Atlantic were found yet.
However, this does not mean that there are no Hanseatic trading vessels to be found in the North Atlantic at all. The only wreck which could be considered as Hanseatic are the remains of the El Gran Grífon (The great Griffin). This ship, which is the oldest known wreck both in Shetland and of all the North Atlantic islands, has a quite unusual history.
As the name already suggests, the Gran Grífon did not end up in Shetland by merchants from Bremen or Hamburg. Instead it was part of the famous Spanish Armada. This was a Spanish fleet which was sent in 1588 by the Spanish King Philipp II to invade England. The operation was a complete failure; the bulk of the fleet was lost after attacks by the English Navy and subsequent bad weather conditions on the North Sea.
The Gran Grífon itself was a former Hanseatic merchant vessel from Rostock, a Hansa Town in the Baltic Sea, and was bought by the Spanish Navy for the Armada. This was not unusual; merchant ships were in this time often converted for military use in times of war. After the ship had been roughly modified, it was used as the flagship for a squadron of 23 supply and troop ships. These poorly armed squadrons, called urca squadrons, consisted of acquired merchant vessels and were commanded by Juan Gomez de Medina. The ship had a tonnage of 650 tons, a length of around 30 m and an armament of 38 unspecified cannons. The original crew of 43 men were supplemented with around 200 soldiers. So all in all carried the ship over 243 men.
After some battles with the English Navy, which took the lives of over 40 soldiers and seamen, the ship was driven to the North of the British Isles. It was accompanied by other Armada vessels like the Barca de Amburgo (probably another converted Hanseatic ship from Hamburg), Castillo Negro and La Trinidad Valencera. After the Barca de Amburgo sank, the Gran Grífon and the Trinidad Valencera took over the surviving men.
Shortly afterwards the contact between the ships was lost and the Gran Grífon sailed in a South-West direction, trying to get back to Spain through the Atlantic. However, after the ship reached the latitude of the Galway Bay in Western Ireland, a strong gale from the South-West got up and flouted the Ship back North. Since the ship was heavily damaged, Juan Gomez de Medina decided to search for the nearest possible land. This turned out to be Fair Isle, the most southern and remote island of the Shetland archipelago. The ship tried to anchor in vain before it was driven ashore and ended up on a cliff at Stroms Hellier at the Southeastern end of the island in September 1588. Most of the remaining crew members and soldiers, including Gomez de Medina, managed to escape from the ship before it disappeared in the waves.
For a long time, the wreck remained untouched in the 9-18m deep water. In 1728, W. Irvine salvaged three cannons from the wreck. An archaeological excavation was carried out between 1970 and 1977 by the Institute of Maritime Archaeology of St Andrews University, led by C. Martin. Unfortunately the wreck was barely preserved. Parts of the stern, a rudder pintle, cannons of different sizes, coins, cannon balls, musket bullets and lead ingots were found, recorded and removed. Other, smaller finds like the handle of a pewter or “Hanseatic” flagon, as well as a curved iron blade, were also recovered. The wooden part of the stern was preserved under a boulder, which had tumbled down from the nearby cliff. Most of the finds were brought to Lerwick, where they can be partly seen at the Shetland Museum.

Natascha Mehler, 27 April 2017
In the 16th century there were approximately 25 trading stations in Iceland which were regularly frequented by merchants from Bremen, Hamburg, Oldenburg or Lübeck. Most of these stations lay in the western part of the island, around the Snæfellsnes and Reykjanes peninsulas and in the Westfjords, because these were the areas where most fishing settlements were located and where cod, which was transformed into the main trading commodity stockfish, was abundant.
It is difficult to tell what these German trading stations looked like because none have survived until today. In 1604, the Danish king Christian IV ordered to tear down all German buildings in Iceland, as a consequence of his imposition of the Danish trade monopoly (1602–1787). During the early 17th century many of the German trading stations (such as Grundarfjörður in the image above) were taken over by Danish traders and subsequently developed into permanent and more substantial settlements, many of which still exist today. What we don’t know is whether the Danish traders really tore down the German buildings, as was the will of the king, or simply re-used the buildings and infrastructure. The latter would certainly have been more practical in a country where building material was scarce.
Luckily, a handful of German trading sites did not develop into modern settlements and remains have survived until today. One of them is situated on the small tidal island of Landey at the northern side of the Snæfellsnes peninsula, near the present farm of Bjarnarhöfn. Written sources mention a trading post visited by merchants from Oldenburg and Bremen in the 1590s, but the amount of information from the surviving documents is very low. In 1593, Carsten Bake from Bremen acquired a three-years license for the harbour, and afterwards the harbour was given to the count of Oldenburg. In 1599, a request by the count to renew the license for Landey was denied by the Danish king because it was already in use by someone else. Who this person was is not mentioned.
Today, Landey is a small island only used by sheep for grazing. The outlines of two buildings are clearly visible. They are situated on a small plain near a beach that was used as a landing site, to pull up small boats. The western side of the island faces a bay called Kumbaravogur, and on the other side of that bay lies Kaupstaðartangi, a headland where the remains of a trading station called Kummerwage have survived. This close proximity could be the reason why Landey started to be used as a trading post in the first place, as Kummerwage had been a harbour of Bremen merchants for a long time, but was given to Joachim Kolling from Oldenburg in 1580. Bremen tried hard to get the harbour back, but without success. The merchants of Bremen must have tricked the Danish king in requesting a license for the nearby Landey. When the king realised his mistake he included the clause that the license would go to Oldenburg after the Bremen one expired.
A trial excavation conducted with Fornleifastofnun Íslands at Landey in the summer of 2016 has shown that both buildings on Landey were indeed dwellings, although rather simple constructions. The walls were built in the Icelandic way, made of turf with stone linings. A fire place was discovered in the western building and no signs of furniture or other equipment were found. However, ten fragments of a ceramic cooking pot made of red earthenware were discovered. ICP-MS analysis of the sherds (conducted by Torbjörn Brorsson, KKS) has shown that the pot was made in Bremen, or in very close vicinity thereof (e.g. in Oldenburg).
The building to the east has two inner partition walls which indicates that it could have been used as a storage facility. Taking the scarce written and archaeological evidence together we can conclude that the buildings were indeed dwellings of some sort but only used for a very short time. This corresponds well with what we know about the Icelandic trading stations from other written sources: they were only used during the summers, when the foreign vessels were in Iceland, and their owners did not invest in solid infrastructure because they were not sure whether they would return the next summer. For Landey, records only exist for the 1590s.
Written sources indicate that merchants generally slept in the dwellings on land while the ship´s crew stayed on board. However, the excavations at Landey give food for thought. A Northern German merchant might have found it more comfortable to stay on board than to spend his nights in a damp and dark turf building…
