  Tapestries probably played a vital role in visual and oral storytelling in Scandinavian Viking Age culture. The way tapestries were displayed, the depiction of narratives in the weave as well as their size and form may have been used as tools in complex performances. Poems in Edda, written down in the Middle Ages, suggests that an interaction between the weaver, the narrative and the oral storyteller formed the core of such performances, each with their own important role. In this paper, the tapestries from the Oseberg grave dating to the 9th century are used as an example of how interior textiles may have played a part in this form of social interaction.

  Abstract Archaeological textiles are often highly fragmented, posing significant challenges for reconstruction and analysis. Human experts traditionally rely on technical analyses, such as thread counting, to match fragments and determine their origins. However, this process is labour-intensive and time-consuming, especially for degraded artefacts such as the Oseberg tapestry from the Viking Age. Despite the potential for automation, existing computational methods have proven insufficiently robust, lacking the nuanced approach that human expertise offers. We propose a framework for automating thread counting in textile images using a feature extractor to capture thread counts in vertical and horizontal directions. Our method models thread counting as a pulse counting problem, inspired by how humans intuitively count threads. It involves analysing traces of pixel values from binary and gradient images to estimate thread density. Our method was compared to measurements by human experts, and while it tended to overestimate thread counts, it showed promising results in clustering fragments. Specifically, 14 out of 27 fragments were grouped in alignment with archaeologists’ hypotheses regarding their origins. Our method offers a valuable tool for digitally reconstructing archaeological textiles, improving efficiency in analysing and matching fragmented artefacts. Future work will focus on refining our approach with advanced thresholding techniques, modelling complex weaving techniques and utilizing hyperspectral images to improve accuracy in identifying complex weaving structures and mixed thread materials.

  In this article, we present the results from an archaeological survey on a Cistercian monastery on Hovedøya outside Oslo, seen in the light of the Cistercians’ rules and guidelines for diet and self-sufficiency. Food remains, in addition to preserved letters of land transactions and toll rolls, can shed new light on the monastery`s strategies to meet both the demands of self-sufficiency and the order’s strict regulations regarding nutrition, discipline, and self-control. According to their rules and international instructions, the Cistercian diet should primarily consist of vegetables, fish, and bread, with an increasing focus on fish from the late thirteenth century onwards. How did they manage in one of the order’s northernmost outposts? In the ongoing discussion about sustainability and food safety, knowledge of how the medieval Cistercians took advantage of the local opportunities that were given them may add a new perspective.

  lthough interest in food history has increased in recent years, it is still an under-researched, under-used and under-communicated field. This book’s ambition is to contribute new and valuable knowledge to the field of food history, as well as to inspire more research in it. The conference “Tracing, shaping, reshaping Culinary Heritage” was held in the University of Oslo’s Botanical Garden at Tøyen in Oslo in September 2022. The overall theme was to investigate and illuminate how food history can help us understand our past, present and future society. At the conference scholars from the disciplines of sociology, archaeology, anthropology and history, in addition to representatives of the value chain in food production, provided new knowledge about local food cultures of the past. At the same time, the food value chain is focusing on the creative use of past food culture and on taking food heritage into the future. In this way, we connected the history of food to the past, the present and the future. This perspective is also reflected in the contributions presented in this book

  I 1624 brant Oslo. Den nye byen Christiania ble etablert på andre siden av Bjørvika, nedenfor Akershus festning, og de nedbrente restene av Oslo ble jevnet med jorden. Området ble tatt i bruk til landbruk, og slik forsvant det gamle Oslo gradvis fra syn og sinn. Først med de store gravearbeidene for jernbanen fra slutten av 1800-tallet dukket restene av hus, kirker og borger igjen opp fra glemselen. De siste årene, med byggingen av Follobanen og utviklingen av Bjørvika-området, har arkeologiske utgravninger avdekket omfattende spor av middelalderens by og havn. Gjennom bidrag fra arkeologer, historikere, kunsthistorikere, bygnings-, religions-, tekst- og stedsnavnforskere, latinister og runologer, samler denne boka ny forskning og nye resultater fra disse utgravningene. Selv om mange sider av byens historie for alltid vil være tapt for oss, er kunnskapen om det gamle Oslo større enn noen gang.

  Abstract Cattle and, to a lesser extent, sheep/goat and pigs, were crucial components of Norway’s socio-cultural and economic dynam- ics in the Middle Ages. Zooarchaeological analyses of faunal samples from different urban sites reveal that changes in cattle husbandry practices occurred in Norway over the medieval period, and especially in its early phases. This is clearly demon- strated in the case of medieval Oslo, where an in-depth zooarchaeological study provides the first comprehensive review of cattle husbandry strategies. In the first centuries of the medieval period (11th -mid 12th c. AD), cattle were mainly raised for milk and meat production, while fewer young and more numerous older individuals, most of which probably oxen, were present from mid 12th -13th c. AD onwards. This hypothesis is supported by biometrical analyses of cattle postcranial bones, indicating changes in the sexual composition of cattle herds over time. Therefore, from ca. mid 12th -13th c. AD onward, cattle seem to have been more used for ploughing and, only once old, to have been culled for their meat. In turn, this evidence suggests that more arable lands had to be ploughed, especially in eastern and central Norway. Here, demographic growth and settlement expansion would have led to an increase in food demand; at the same time, more favourable climatic condi- tions might have contributed to an increase in the availability of arable fields. This article suggests that medieval Norwegian farming was not static as historically thought, but rather connected to wider-scale agricultural innovations characterising other parts of medieval Europe.

  Archeological textiles can provide invaluable insight into the past. However, they are often highly fragmented, and a puzzle has to be solved to re-assemble the object and recover the original motifs. Unlike common jigsaw puzzles, archeological fragments are highly damaged, and no correct solution to the puzzle is known. Although automatic puzzle solving has fascinated computer scientists for a long time, this work is one of the first attempts to apply modern machine learning solutions to archeological textile re-assembly. First and foremost, it is important to know which fragments belong to the same object. Therefore, features are extracted from digital images of textile fragments using color statistics, classical texture descriptors, and deep learning methods. These features are used to conduct clustering and identify similar fragments. Four different case studies with increasing complexity are discussed in this article: from well-preserved textiles with available ground truth to an actual open problem of Oseberg archeological tapestry with unknown solution. This work reveals significant knowledge gaps in current machine learning, which helps us to outline a future avenue toward more specialized application-specific models.

  Marine resources have been important for the survival and economic development of coastal human communities across northern Europe for millennia. Knowledge of the origin of such historic resources can provide key insights into fishing practices and the spatial extent of trade networks. Here, we combine ancient DNA and stable isotopes (δ13C, δ15N, non-exchangeable δ2H and δ34S) to investigate the geographical origin of archaeological cod remains in Oslo from the eleventh to seventeenth centuries CE. Our findings provide genetic evidence that Atlantic cod was obtained from different geographical populations, including a variety of distant-water populations like northern Norway and possibly Iceland. Evidence for such long-distance cod trade is already observed from the eleventh century, contrasting with archaeological and historical evidence from Britain and other areas of Continental Europe around the North and Baltic Seas, where such trade increased during the thirteenth to fourteenth centuries. The genomic assignments of specimens to different populations coincide with significantly different δ13C values between those same specimens, indicating that multiple Atlantic cod populations living in different environments were exploited. This research provides novel information about the exploitation timeline of specific Atlantic cod stocks and highlights the utility of combining ancient DNA (aDNA) methods and stable isotope analysis to describe the development of medieval and post-medieval marine fisheries.

  Archaeological textiles are often highly fragmented, and solving a puzzle is needed to recover the original composition and respective motifs. The lack of ground truth and unknown number of the original artworks that the fragments come from complicate this process. We clustered the RGB images of the Viking Age Oseberg Tapestry based on their texture features. Classical texture descriptors as well as modern deep learning were used to construct a texture feature vector that was subsequently fed to the clustering algorithm. We anticipated that the clustering outcome would give indications to the number of original artworks. While the two clusters of different textures emerged, this finding needs to be taken with care due to a broad range of limitations and lessons learned.

  Two golden textiles were found in a Viking Ship grave at Gokstad in Norway. Apart from brief overviews, the materials, techniques and find context of these textiles have not been described before in detail. The silk-and gold embroidery was made with stem-stitch and simple laid-work. A madder-dyed silk thread was used to make the flower pattern, in combination with a gold thread consisting of lamella made of some 80percent pure gold with a core of silk. A similar gold thread was used in a narrow band found together with the embroidery. The approximately 4- 4.5 mm wide band is probably a remnant of tablet weaving. Both embroidery and band were found hidden inside a hollow ridgepole holding the roof of a grave chamber. The precious gold-and silk materials as well as the time-consuming and specialised technology used to make the gold thread suggests that these textiles were highly valuable.

  The last technological developments in chemical analysis with high resolution-mass spectrometry allow a more precise, secure, sensitive, and accurate detection of markers preserved in archaeological vessels, even as trace or ultratrace level. We develop a new metabolomic-based approach and applied on a series of 19 soapstone vessels from Medieval Norway. The very nature of the ancient materials contained in the vessels could be identified from the fatty acids, sterols, phenolics composition. Aquatic resources, identified from their fatty acid composition and specially isoprenoid acids, isomeric 22:1 acids, and their heat-degraded markers ω -(o-alkylphenyl)alkanoic acids, have largely been exploited during Medieval times. The metabolomic approach brings also in light the consummation of fruit derivatives, especially grape, apple, and plum derivatives identified from their aldaric, phenolic or suggested from their enterolignans. This pioneer method clearly open new research facilities for the comprehension of everyday life of ancient populations from their domestic vessels.

  The grave from Gokstad in Norway, dating to ca 900 AD, is one of the best-preserved Viking Age ship graves in the world. The grave mound contained a variety of goods along with human remains, buried in a Viking ship. Several textiles, including embroideries and shreds of what might have been the ship’s tent, were also found. The colors of the textile fragments are now severely faded, but the high quality of the embroidery made of gold and silk threads is still apparent. The style of the embroidery is exceptional, having no equivalents in other Scandinavian graves. The analyses by HPLC coupled with both diode array and mass spectrometric detectors revealed that the striped “tent” cloth as well as the silk thread used for the embroidery were originally dyed with anthraquinones of plant origin (alizarin, purpurin, pseudopurpurin, and anthragallol), markers of madder-type dyestuffs.

  Extraordinary objects, things that convey collective narratives as well as a record of conservation evoke extraordinary feelings. Both the physical characteristics of the objects and the myths surrounding them may increase their meaning, lending them an inherent power. The design, language of form, as well as the materials used are essential elements in creating the objects’ charisma and in forming the stories that are told about them. The present volume explores the concept of charismatic objects and their material world through nine papers focusing on historical examples dating from the Roman Period to the late Middle Ages.

  A woven wool tunic with damaged sleeves and repairs to the body dating from AD 230 to AD 390 was discovered on the Lendbreen glacier in Oppland County, Norway in 2011. The Norwegian Mountain Centre in Lom (Norsk Fjellsenter) and the Museum of Cultural History at the University of Oslo each commissioned a reconstruction of the tunic for exhibition and research into prehistoric textile production. The original was woven in 2/2 diamond twill with differently coloured yarns producing a deliberate and even mottled effect. The reconstruction project investigated the materials required, the likely tools used and the weave, with new investigations into the processes of collecting, sorting, and spinning the wool, the thread system, the finishing treatment and sewing to produce two tunics as they might have been as new with complete sleeves and no repairs. Estimates for the labour required for each stage suggested a total of just over 402 hours per tunic.

  When Viking Age house interiors are reconstructed, the focus is usually on the fireplace and the placement of tables, benches and beds. These features help us understand how people lived. However, we often forget that textiles, such as blankets, sheets, tablecloths and wall hangings, were also important in everyday life. Textiles were used for comfort, cleaning and decoration, and they helped tell stories as well as signal a person’s or family’s social status. Most Viking Age textiles that have survived are found in graves. These include not only clothing but also bedding, pillows and fabrics used to wrap objects. A burial can be seen as a kind of room for the dead, filled with items that reflect how people lived and what they valued. Because of this, grave finds are important when discussing the interior textiles used in Viking Age houses. Wall hangings are mentioned as status symbols in the Icelandic sagas, and examples from the late Viking Age and early medieval period have been found and preserved in churches, giving us insight into their use and value. Old Norse texts also mention soft furnishings such as tablecloths and handcloths, and the use of interior textiles can be seen on the Bayeux embroidery. Other types of iconography, such as on rune stones and picture stones, help us understand how interior textiles may have been used. By combining information from textiles, written sources and iconography, and by applying different approaches, the chapters in this book offer various perspectives on how interior textiles were used in the Viking Age, why they were needed and how valuable they were.

  Archaeological textile artifacts are often fragmented and human experts need to solve a puzzle to find matching pieces and reconstruct the original. This is a challenging task due to missing or degraded fragments, deformations and fading. Often it is not even known whether fragments come from the same object or not. A good example is the Oseberg Tapestry from the Viking Age [1]. Matching is usually done by experts who rely on technical analysis of the textile. One important criterion for identifying fragments from the same object is thread count (i.e. number of threads per centimeter) in the warp and weft directions. This is a tedious and time-consuming process. Computer science literature shows that current algorithms are not robust enough to solve the puzzle of archaeological textiles and proposes taking inspiration from the criteria that humans use [2-4]. To address this, we propose a framework for automatizing thread counting in textile images. We created a feature extractor, which captures thread count in vertical and horizontal directions. Thread count is usually measured by selecting several 1x1cm areas on the tapestries (we refer to this area as a patch), counting the threads and averaging the results. Archaeological textiles often have holes where threads are missing due to decomposition. The experts take this into account when they decide where to count. We modeled the thread count extraction as a pulse-counting process, inspired by how we intuitively count threads. For counting vertical threads, we trace the patch in the horizontal direction and count the thread by finding the number of occurrences of two consecutive vertical edges. Similarly for the horizontal threads we trace the patch in vertical directions. Our proposed thread flow begins with applying Otsu’s binary thresholding to the patch. Then we take all the pixel values for all columns in the same row to model the horizontal tracing of the patch. The pulse front is obtained by calculating the absolute approximate derivative of the trace. The number of pulses, which represent the number 𝑋(2: 𝑛) − 𝑋(1: 𝑛−1) of thread, is obtained by the number of non-zero elements of the absolute approximate derivative divided by two. This operation is repeated all the way from the top to bottom patch and the majority thread count is returned as the thread density of the patch. We compared our algorithm with the ground truth counted by experts. The preliminary results show that our method overestimates thread count. The final results will be presented at the conference. However, thread count features extracted with our method, provided promising results when used for clustering. Twelve out of 27 fragments clustered using thread count alone, were aligned with archaeologists’ hypotheses on which fragments belong together. The Oseberg Tapestry is a challenging case-study also because its thread systems consist of double threads, which introduces an additional complexity to the machine. The result for simpler scenarios will be also presented. Future work should explore more sophisticated methods for thresholding, such as Sobel to expose edges, and STRESS (Spatio-Temporal Retinex-inspired Envelope with Stochastic Sampling) enhancement preprocessing, to make them more separable.

  A number of food plants in form of seeds as well as pollen are detected through archaeological excavations in medieval towns in Norway. These are in part species other than those mentioned in the recipe books that are preserved from the same period. How should we interpret these discrepancies? Food plants in iconographic sources is another valuable resource. How can we develop new research and public outreach based on all these sources? Welcome to an informal webinar where these questions will be discussed. All participants are welcome to contribute to the discussion during the meeting. We will meet online on Friday the 9th of April from 9 – 10:30. Bring your own coffee, or other botanically inspired beverage. Program: - Introduction to published foodplants and ingrediences in medieval cook books (Marianne Vedeler) - Cultivation and use of a selection of plants from the sources (Anneleen Kool) - Food plants in iconographic sources (Karoline Kjesrud)

  Under arkeologiske utgravninger samles det ofte inn frø og planterester. Fra middelalderens Oslo er det registrert et variert utvalg av vekster som har vært dyrket, importert eller som har vokst naturlig i området. Gjennom mange år har arkeobotanikere analysert disse restene og funnet ut hva slags arter det er. Mange av disse er matplanter. I forskningsprosjektet FOODIMPACT har vi samlet disse resultatene fra en rekke utgravninger og laget oversikter og kart som viser hvor de enkelte artene ble funnet. Utgangspunktet for kartene er en liste av planter som vi vet, eller har god grunn til å tro, ble spist og/eller brukt som medisin av mennesker i Middelalderen. Som bakgrunn for definisjonen av matplanter har vi i hovedsak tatt utgangspunkt i to publikasjoner: Wörterbuch der Pflanzennamen im Altwestnordischen av Wilhelm Heizmann og Liber Herbarum av Henrik Harpestræng.

  Avhandlingen “Clothing the Sacred: Ecclesiastical Textiles from late medieval Scandinavia c. 1400 – 1550,” undersøker hvordan liturgiske tekstiler bidro til en visuell og estetisk opplevelse i senmiddelalderens kirkerom. Gjennom analyser av tekstilskatter bevart i museer og katedralsamlinger i Skandinavia viser studien hvordan tekstiler var instrumentelle for opplevelsen av hellige rom og kropper. Forskningen bygger på et bredt utvalg av kilder som malte avbildninger av tekstiler, inventarlister, liturgiske tekster og samtidige, senmiddelalderske beskrivelser. De åtte kapitlene diskuterer relikviekleder, tekstile relikvarier, gravdekker, alterklær og geistlige paramenter i Norge, Sverige, Danmark, Island og Finland, og viser hvordan tekstiler ble brukt til å pakke inn, tildekke og ramme inn hellige kropper og objekter. Tidligere forskning på middelalderens paramenter har primært fokusert på teknikk og proveniens. Denne avhandlingen bygger videre på slike tekniske studier og utvider perspektivet ved å drøfte tekstilene som performative, retoriske og estetiske objekter. Jeg argumenterer for at en lagvis tekstil påkledning eller tildekking kan forstås som en performativ og konstruktiv handling som rammet inn det hellige. Avhandlingen vever sammen fagfeltene tekniske tekstilstudier og middelalderens kunsthistorie for å avdekke tekstilenes religiøse, materielle og symbolske betydning l i senmiddelalderens kirkerom.
