Weblog of the research project "Between the North Sea and the Norwegian Sea: Interdisciplinary Studies of the Hanse"

Welcome to the weblog of the research project "Between the North Sea and the Norwegian Sea: Interdisciplinary Studies of the Hanse". The aim of the project is to investigate the economic and cultural connections of merchants from Northern German cities, such as Bremen and Hamburg with the North Atlantic islands of Iceland, Shetland and Faroe during the 15th to 17th centuries. The project is based at the German Maritime Museum (Deutsches Schiffahrtsmuseum) in Bremerhaven and funded by the Leibniz Association (2015-2018).The research is carried out by four team members, each with their individual research objectives and disciplinary background. With this blog we want to provide information about the current state of our research, and create a platform to make available results and new knowledge. Read more...

German-Icelandic trade relations: the case of Eiríkur Árnason

Bart Holterman, 30 March 2017

Trade in the North Atlantic was neither simply an exchange of goods between ports in Iceland and in Germany, nor did the islanders stay at home and wait for German merchants to show up each spring. In some cases, more complex relations between islanders and Germans existed, and in what follows we will present an example from Iceland to highlight the complexity of the trade relations between Icelanders and Germans. Germans were not allowed to settle in Iceland, but Icelanders were free to move or travel to Germany, which some did, and established networks of their own. Sometimes these links can be reconstructed in considerable detail with the help of both historical and archaeological sources. In this post, we will focus on one such case, that of Eiríkur Árnason Brandssonar (c. 1530-1586), sýslumaður (bailiff) of Múlaþing district in the East of Iceland.

Eiríkur Árnason was a powerful man in Iceland, who repeatedly got into trouble with Guðbrandur Þorláksson, bishop at Hólar. Eiríkur was appointed klausturhaldari, the keeper of the property of Skriðuklaustur monastery, located in the valley of lake Lagarfljót about 50km inland from the southeastern coast of Iceland. The monastery had been secularized in 1554, and the now royal property was administered by the klausturhaldari. Eiríkur, whose grandfather Brandur Hrafnsson had been the last prior of the monastery, held this office between 1564 and 1578.

So called Bartman jug made of Rhenish stoneware, found in the house of the klausturhaldari of Skriðuklaustur (image Helgi Hallgrímsson).

In 1584, it seems that Eiríkur settled in Hamburg. He embarked on a voyage to Hamburg on the ship of Jochim Warneke and shortly afterwards married Anna Korfemaker and bought a brewery. The next year he travelled back and forth between Iceland and Hamburg and it is most likely that he was a member of the fraternity of St Anne that united most merchants and sailors who travelled to Iceland. In 1586 he died in Hamburg and was buried there at the cemetery of St Jakob.

There are numerous sources which shed a light on Eiríkur’s contacts with German merchants in Iceland. In the fjord now known as Berufjörður, south of Skriðuklaustur, Bremen merchants (who called the fjord Ostforde) had been trading for a long time. In 1575, a conflict broke out between two of them, Bernd Losekanne and Christoffer Meyger, due to alleged mutiny. In the ensuing court case before the Bremen city council, one of the problems discussed was the ownership of a barrel of osemund (iron from Sweden) which Losekanne had sold to Eiríkur Arnason but which was left in the merchant´s booth, of which Eiríkur as bailiff had the keys. Also, a load of vaðmál he left in the booth was destined for a Hamburg merchant named Matthies.

It is clear that during his time as sýslumaður and klausturhaldari, Eiríkur had been trading actively with the German merchants in the area. This is also attested by contemporary objects. From the house of the klausturhaldari stems a complete Bartman jug of the 16th century, a common pouring vessel of that time, produced in one of the major stoneware production centers along the Rhine (such as Frechen, Raeren or Cologne). It is more than likely that this jug was used by Eiríkur who had bought it from the German merchants in Berufjörður. Another link is the gravestone of his mother Úlfhildur Þorsteinsdóttir which is thought to have been imported from Germany by Eiríkur.

Eiríkur’s connections with German merchants probably went further than that. In 1580 Bernd Losekanne and Christoffer Meyger (who had apparently reconciled) complained about interference of Hamburg merchant Matthias Eggers in Ostforde. Eggers, on the other hand, said that he had a general trading license for Iceland which obviously permitted him to use any harbour he liked. Losekanne and Meyger then replied to this that this was unfair because Eiríkur had acquired that license for himself when he had visited the Danish royal court, and had entered into a trade agreement with the Hamburg merchants, in return for a part of their ship. Eggers was also probably the man named Matthies for which Eiríkur had put aside the vaðmál in 1575.

Merchants from Bremen are known to have entered into trade relations with Icelanders as well, but that might be a topic for a future post.

How to recognise stockfish from its bones

Bart Holterman, 22 December 2016

For most readers of our blog, probably the most mysterious part of our research is the work of Hans Christian Küchelmann, archaeozoologist, who uses archaeological finds of fish bones as traces of the late medieval North Atlantic (stock)fish trade. A fish bone found in the ground, however, does not say where the fish once came from or to which fish it belonged. So, how can one identify a stockfish merely by its bones? This blog post will shed a light on that mysterious procedure.

1. Stockfish production

In order to be able to identify a stockfish bone, it is essential to know how stockfish was produced. Luckily, stockfish is made in Iceland and Northern Norway to this day in ways that have hardly changed over the centuries, so in combination with historical sources, we can reliably reconstruct what a medieval stockfish must have been like.

Stockfish is made in polar regions from fish from the Gadidae family where they are hung to dry outside during the winter. Due to climatic conditions this is only possible in arctic regions as the cool weather prevents the fish from rotting before it dries. However, the entrails must be removed before the fish is hung to dry, and the heads are cut off. This is roughly done with two methods: a) the fish is gutted and beheaded, the rest of the body left intact (rundfisk), or b) the fish is beheaded and split in two, removing the entrails as well as most of the spinal column, and then hung to dry. The latter method is called råskjær in Norwegian (rotscher in the Low German medieval documents). As this leaves only a few caudal (tail) vertebrae in the stockfish, most bones of stockfish will come from rundfisk.

2. Species and distribution

Different species of the Gadidae family used in the production of stockfish. Clockwise, starting at the top: cod (Gadus morhua), ling (Molva molva), haddock (Melanogrammus aeglefinus), pollack (Pollachius virens), tusk (Brosme brosme). images: Wikimedia Commons

Different species of the Gadidae family used in the production of stockfish. Clockwise, starting at the top: cod (Gadus morhua), ling (Molva molva), haddock (Melanogrammus aeglefinus), pollock (Pollachius virens), tusk (Brosme brosme). images: Wikimedia Commons

As mentioned, stockfish was made from species of the Gadidae family. A trained eye will have no problem recognising a bone from a Gadidae fish in most cases. Due to long travel times and the absence of freezers in pre-industrial times, these fish could only be transported in preserved form, either salted or dried. Hence, a find of a Gadidae bone, especially on inland sites, hints at having belonged to a stockfish.

However, in coastal areas these fish were also eaten fresh, so how do you know a bone is from stockfish in that case? It is necessary to look at the distribution of the different Gadidae species. Three of the species that were used for producing stockfish, namely saithe (Pollachius virens), ling (Molva molva), and tusk (Brosme brosme) do not appear in the Southern North Sea and Baltic Sea. Bones from these three species found on the European mainland, especially in inland areas, are therefore a strong indicator for stockfish.

3. Size

By far most of the stockfish, however, is and was made from cod (Gadus morhua), which does live in the Southern North Sea and the Baltic Sea. Bones of cod could therefore also belong to locally caught (and therefore not dried) fish. So we need another indicator to distinguish a stockfish from fresh local cod. The cod which live around the German shores are mostly smaller juveniles, older and larger fish live further North. By comparing the size of the bones to those of complete skeletons it is possible to estimate the size of the fish they belonged to. Bones belonging to fish larger than c. 75cm are less likely to have been local catch and were probably imported in dried form. Moreover, a high prevalence of fish in a specific size range is an indicator of stockfish, as these were sorted and sold according to size, whereas local catches will likely show a higher variety of fish in different sizes.

4. Bone composition

Because the head of the fish was cut off and remained at the production site one can expect head bones to be absent at consumption sites. Indeed, we find a clear overrepresentation of post-cranial (i.e. bones not belonging to the head, from cranium: head) bones on some sites in mainland Europe. On some archaeological sites in Iceland, for example, there are almost only cranial bones which is a clear sign that stockfish was produced there.

The cleithra (top), which are located directly behind the head of the fish, but remain when the fish is beheaded, clearly belong to larger individuals and are systematically cut off on the right, indicative of stockfish production.

5. Cutting and hammering marks

The production and consumption of stockfish can also leave traces on the bones themselves. For example, the heads of fish were chopped of in a standardised way, leaving clear-cut chopping edges on the bones of the shoulder girdle directly behind the head. Also, the preparation of stockfish required hammering the fish for a while before soaking it, to make the flesh softer. As we have seen from our own experiences in preparing stockfish, this procedure can destroy or deform the vertebrae of the fish. Hence, deformed or broken vertebrae can be a sign of stockfish consumption in the archaeological record.

6. Isotope and aDNA analysis

Further, more advanced evidence from the North Atlantic stockfish trade can be acquired by applying methods such as aDNA analysis and isotope analysis, which can potentially retrace the remains of an animal to the area in which it lived. However, an explanation of these techniques might be a topic for a next post.

The cultural impact of German trade in the North Atlantic

Natascha Mehler, 19 October 2016

In the 16th and 17th centuries, the North Atlantic islands of Iceland, Shetland, and to some extent also Faroe, were closely tied to the cities of Bremen and Hamburg. Merchants from these hanseatic cities regularly travelled North to exchange goods such as grain / flour, beer, timber and tools for stockfish and sulphur. In the second half of the 16th century about 500 to 750 merchants, sailors, craftsmen, priests and others from Hamburg and Bremen spent their summers in Iceland. On the other hand, a considerable number of Icelanders used Hamburg and Bremen ships to travel to the continent, e.g. to be educated in jurisprudence or theology at the universities in Copenhagen, Rostock and Wittenberg. They brought back new knowledge that changed the insular societies.

The German presence on the islands and the stay of islanders in Northern Germany had a profound impact on the North Atlantic insular societies. Tracing this impact will be the main aim of an interdisciplinary research seminar that takes place from 26 to 28 October 2016 at the museum Schwedenspeicher in Stade near Hamburg. It is organized in cooperation with the archive Stade and the museum Schwedenspeicher Stade.

The main aim of this seminar is to trace and disentangle the forms of impact. The topics and questions we want to discuss during the seminar include:

  • What role did the German connections play in the assertion of the reformation in Iceland, Shetland and Faroe? What was the position of the Danish and Scottish crown? How did religious life change on the island?
  • What was the cultural effect of the reformation and how did the new scholarship change the insular societies? How did knowledge transfer happen?
  • What role did hanseatic measurements (e.g. the Hamburg ell) and coinage (e.g. Reichsthaler) play on the islands and how were their values converted into the Icelandic, Faroese and Shetland value system? Did the different value systems effect the economic connections?

Worth a fortune: Icelandic gyrfalcons

Natascha Mehler, 11 August 2016

Falco_rusticolus_1

Throughout the medieval and early modern period, Icelandic gyrfalcons were highly valued at the courts of European rulers and they were worth a fortune. Indeed, Frederick II (1194-1250), Holy Roman Emperor, already noted in his treatise De arte venandi cum avibus that the best falcons for use in falconry were gyrfalcons (…et isti sunt meliores omnibus aliis, Girofalco enim dicitur). The reason for this was that of all falcon species, gyrfalcons (Falco rusticolus) are the largest and most powerful. Their plumage varies greatly from completely white to very dark, of which the white variety was the most valued hawking bird in the Middle Ages, and still is today. They only inhabit sub-arctic and arctic areas, with their highest population density in Iceland (one pair per 150-300 km²). During the breeding season (roughly February to June) there are today 200-400 nesting pairs in Iceland, and in the winter the population increases to 1.000-2.5000 individuals, due to migrating birds from Greenland.

Written sources from the 16th century, when German merchants from Hamburg and Bremen dominated the trade with the North Atlantic islands, give us a better insight into the falcon business with Iceland. Matthias Hoep, a Hamburg merchant, has left behind a collection of account books (1582-1594) which show us that he traded in many commodities such as fish, timber, and tools, and specialized in the trade of falcons. Hoep employed falcon catchers to catch birds in Iceland for him and he made specific contracts with them. The books record a great number of falcons and other birds of prey that he bought from falcon catchers and which he then sold on. On 5 April 1584, Hoep made a contract with the falcon catchers and brothers Augustin and Marcus Mumme which he commissioned to travel to Iceland to catch falcons. The contract specified the bird species, the conditions of the birds upon delivery, and the prices Hoep was going to pay after the successful return of the Mummes from Iceland:

“On 5 April [1584] I have dealt in my house with Augustin and Marcus Mumme, in the name of god, that they shall sail to Iceland in the name of god, and we agreed that I will give for each pair of falcons 11 ½ daler, and 2 tercel [male falcons] for 1 falcon, and what is blank shall be counted as a red [unmoulted] falcon. But what is white and moulted once, or moulted twice and beautiful, for those I shall give them 20 daler for each falcon and 10 daler for a tercel. But what has moulted three times we shall agree upon with good will, and if god and luck provides them with white falcons, I will give the one who catches them black cloth for a jacket of 2 ½ ells, all of this is validated with a denarius dei of 1 sosling each, and both brothers have promised with an oath to bring the best birds they can get and to take no birds away, neither in Iceland nor during the journey back, until they have all been delivered to me.“

Roughly five months later, in September 1584, the brothers returned from Iceland and handed over 49 birds to Matthias Hoep.

Carta Marina

Detail of the Carta Marina (1539) showing the coat of arms of Iceland (stockfish), with a gyrfalcon (FALCO ALBI) above.

Later documents tell us how the shipping of the falcons was done. During the 17th century, a Danish falcon ship went to Iceland annually to transport falcons from Iceland to Copenhagen. The falcons were kept below the deck and sat on poles which were lined with vaðmál. During the journey, the birds were fed with meat of cattle, sheep or birds, dipped in milk, and when they were sick, they were fed with a mix of eggs and (fish) oil. Upon arrival of the birds in Hamburg, Mathias Hoep checked their health and quality and he considered them in good state after they had eaten three times and their feathers were not broken.

Most of the birds that Hoep received were sold to English merchants such as John Mysken who bought 55 birds of prey in 1584 and had them shipped to England, most likely to be sold to the English court. It is likely that Hoep also had good contacts with Icelanders, both in Iceland and in Hamburg. His professional network may have included Magnús Jónsson (c. 1530-1591), who had studied law in Hamburg, probably until 1556. In Iceland he became chieftain and sýslumaður (sheriff) at Þingeyjaþingssýsla and Ísafjarðarsýsla, districts in the North of Iceland with a very high density of falcons. No wonder his seal from the year 1557 shows a gyrfalcon in the centre.

Siegel_1 small

Seal of Magnús Jónsson, dated 1557. The priest Ólafur Halldórsson, a contemporary of Magnús Jónsson, described the seal in a poem: „Færði hann í feldi blá, fálkann hvíta skildi á, hver mann af því hugsa má, hans muni ekki ættin smá.” (transl. „he carried in a blue field, a white falcon on his shield, so that everybody shall think his family is not insignificant“).

In the second half of the 16th century, king Frederick II of Denmark-Norway (1559-1588) started to regulate the export of falcons to foreign countries. From the 1560s onwards, foreign falcon catchers needed to buy a permission (Icel. fálkabréf, falcon letter) to catch falcons.

Were falcons also caught in Shetland or the Faroes?

We have not found any written evidence for that. The obvious reason for this is that there are not many falcons around in Shetland and the Faroes. Gyrfalcons only appear as vagrant birds, and peregrine falcons (Falco peregrinus) exist in Shetland only in small numbers. However, it is worth pointing out that in the years 1601 to 1606 one Tonnies Mumme is recorded to have sailed each summer from Hamburg to Shetland. We do not know whether this is the same Tonnies Mumme that is reported as falcon catcher in Iceland in previous years, or whether Tonnies is related to the Augustin and Marcus Mumme mentioned above, but it seems very likely. He may have tried his luck in Shetland, or might have changed his profession and have traded in other items.

Sailors, merchants and priests: people on board the ships heading North

Bart Holterman, 13 May 2016

The general history of the northern German trade with the North Atlantic is relatively well known but we know very little about the persons involved in this trade. This is especially true for the men that manned and sailed the ships that headed North.

Luckily, there are a couple of sources pertaining to the North Atlantic trade that give us a good insight into the people on board the ships. First, two boarding lists from Oldenburg for ships trading with Iceland in the 1580s have survived. Second, there is the magnificent book of donations of the Hamburg confraternity of St Anne, the socio-religious organisation behind the trade with Iceland, Shetland, and the Faroe Islands. From the 1530s onwards, the register lists the alms spent to the confraternity by the people on board of nearly every ship that returned to Hamburg, resulting  in a more or less complete register of boarding lists.

Bild Bart

On board a sixteenth-century ship: detail of the epitaph for the ship´s priest Sweder Hoyer (deceased 1565) from the St Jacob church in Lübeck. Note: this image does not necessarily reflect the situation on board the merchant ships in the North Atlantic.

From these sources we can learn that the number of people on board varied greatly, ranging from 77 on larger ships up to around 10 on board the smallest vessels. For Iceland, it was not uncommon to have more than 25 people on board. Ships sailing to Shetland and the Faroe Islands had less people on board, usually 15-20.

This difference in number of people on board was mainly caused by the number of merchants on board. The sizes of the crews were relatively similar on each ship, because 10 to 15 people were needed to sail the ship, regardless of its size. A typical crew consisted of:

– Skipper (schipper). He was the captain, the leader of the ship, often also one of the merchants, and (partly) shipowner.
– Helmsman (sturman), the one who steered the ship and had navigational knowledge.
– Chief boatswain (hovetbosman), the leader of the sailors.
Schimman, the officer responsible for rigging and other technical things.
– Cook (koch).
– Carpenter (tymmerman), responsible for repairs to the ship.
– Gunner (buchsenschut), responsible for the defense of the ship.
– Barber (bartscher), who had medical knowledge, but lacked on most ships.
– 2-4 sailors (bosman).
– 1-2 ship boys (putker), young sailors in training.

Besides these, ships transported merchants and their servants, falcon catchers, priests, and passengers from the islands which used the regular traffic to travel to and from the European mainland.
