Trapèzes, fléchettes et autres pointes – a new publication!

« Trapèzes, fléchettes et autres pointes : évolution des armatures du second Mésolithique au Néolithique ancien entre Jura et Préalpes suisses. » was just published as part of a volume full of French, Belgian and Swiss Mesolithic goodies. It has it all: lithic technology, typology and use-wear. Enjoy your reading!

You can buy the book here. Or surely, your preferred local bookshop will be able to organise it for you as well.

The rich lithic assemblages from the sites Arconciel/La Souche and Onnens/Praz Berthoud provide new insights into the end of the Mesolithic in western Switzerland. The continuous stratigra-phic sequence at the rock-shelter of Arconciel/La Souche (canton of Fribourg) was excavated between 2003-2012. It evidences the repeated occupation of the site between 7100-4800 BC. The numerous projectile points found here show the typological development of this artefact category throughout its occupation. This development is characterised by the appearance of Late Mesolithic blade and trapeze industries just before the middle of the 7th Millennium BC and a continuing tradition of production into the 5th Millennium BC. Macro- and microscopic use wear analysis of a sample of artefacts allows the discussion of the function of artefacts which are habitually called projectile points. These analyses indicate multiple uses of the artefacts throughout the site’s occupation and show how those artefacts used as projectile points were probably hafted. Excavated between 1997-2004, open-air site Onnens/Praz-Berthoud (canton of Vaud) is another rare example of a recently excavated site dating to the end of the Mesolithic on the Plateau Suisse. In addition to a comparable corpus of Late Mesolithic projectile points, an assemblage of Early Neolithic, 5th Millennium lithic artefacts extends the chronological range offered by Arconciel/La Souche. Although there are small differences between the projectile point assemblages from the two studied sites, there are many parallels as well. This is especially true for the symmetric and rectangularly shaped trapezes and some of the so-called “evolved” points. A diversification of shapes can be observed towards the end of the Mesolithic. This diversification is accompanied by an increasingly asymmetric trapezes and the appearance of small, asymmetric points with concave bases, called “evolved” points or “fléchettes”. With time these small points show ever increasing inverse and invasive retouch, slowly developing the characteristics of Early Neolithic points. The comparative study of two assemblages of projectile points provides new insights into the typological characteristics and their developments throughout the End of Mesolithic and the beginning of the Neolithic north of the Alps. This study increases our knowledges of the Late Mesolithic of the Swiss Plateau, while the archaeology of the following period, esp. that between 4800 and 4500 BC remains difficult to grasp here. Little comparative material is momentarily available for the rare material from this period from Onnens/Praz Berthoud.


Avec chacun de riches séries lithiques, les deux sites d’Arconciel/La Souche et d’Onnens/Praz Berthoud viennent compléter nos connaissances de la fin du Mésolithique en Suisse occidentale. L’abri sous roche d’Arconciel/La Souche (canton de Fribourg) a comme principale caractéristique une stratigraphie conséquente, avec des phases d’occupation qui se succèdent chronologiquement presque sans interruption de 7100 à 4800 av. J.-C. Il livre également une série importante d’armatures dont l’évolution typologique jalonne le remplissage de l’abri. En plus d’un corpus comparable du second Mésolithique, le site de plein air d’Onnens/Praz Berthoud (canton de Vaud) vient quant à lui apporter un assemblage de pièces qui sont datées dans la continuité au cours des quelques siècles postérieurs à 4800 av. J.-C. L’observation des séries de ces deux sites apporte des élé-ents de caractérisation typologique pour la fin du Mésolithique au nord des Alpes. En plus de cette approche typologique, la fonction de ces pièces définies comme armatures est également questionnée avec l’analyse tracéologique de quelques artefacts d’Arconciel/La Souche. Les résultats de ces observations conjointes mettent en évidence la diversité des armatures de la fin du Mésolithique avec une évolution des trapèzes qui deviennent de plus en plus asymétriques, parallèlement à l’apparition de petites pointes dites « évoluées » (fléchettes, pointes asymétriques à base concave) tendant vers des pièces davantage recouvertes de retouches rasantes, jusqu’à celles caractéristiques … (auch auf Deutsch unten) Continue reading


From the Mesolithic to the Bronze Age and back again

It is not all Mesolithic in this archaeologist’s life. Last year around this time I took a break from my PhD-research, mainly to earn some money. It turned out it was not bad either to gain some distance from it and to then return to it with a fresh mind almost a year later. It also meant this blog went on a little hiatus. But isn’t it amazing, that after more than 10 years (!!!) it’s still going?! In the meantime, I joined a small team of the Service Archéologique du canton de Berne on a rescue excavation of a Middle/Late Bronze Age settlement near the Lac du Bienne in western Switzerland. It was a geologically interesting location and the site helped to fill a chronological and geographical hole in the prehistory of the region. The famous lake side villages give us a good understanding of the region’s occupation during the Late Bronze Age and the Neolithic. The period in between is sadly less well known in the region. Because of their early discovery and the amazing preservation of organic materials, the focus of archaeologists in the region has long been on these lake side villages. What took place during prehistory beyond these lakes was considered less interesting. The past years has seen a number of rescue excavations and research projects addressing these themes and our excavation of “Sutz-Lattrigen Hauptstrasse 57, 59, 59a” plays its own small part in that.

You wouldn’t think it from this photo, but for most of the excavation we were very lucky with the weather. This changed in December…

Our initial report has now been published in the Jahrbuch Archäologie Bern 2018 (full citation below). We were able to excavate part of a settlement dating to the Bronze Age C/D – Ha A1 (that is the Middle to Late Bronze Age). Apart from building remains (C14-dated to around 1500-1270 cal BC) and a large amount of ceramics and some metal finds, we also discovered a large cup-marked erratic boulder (“Schalenstein” in German). In fact, it was a regular visitor to the site, 8-year-old budding archaeologist Nahly P. who discovered the cup marks! She lives nearby and often came to visit us with her mother or grandmother to see what we were finding and helped us, of course using her own brush and trowel. The erratic seems to have been placed in a pit with some care and deliberation, together with four smaller boulders. Three of the latter were placed at the same depth in a row in front of the section with the cup marks. Many cup-marked stones are known from the region and from Switzerland in general. Few, however, are found in a prehistoric settlement context and few are secondarily deposited in a pit. When and why this happened will remain unknown for now. Two radiocarbon dates from small charcoal flakes taken from the pit fill date to the Middle Ages, but sadly this tells us very little as it is hard to known how and when these tiny charcoal particles got into the fill.

Finding this cup-marked stone reminded me of something Prof. Richard Bradley wrote in his classic The passage of Arms:

“Much of the difficulty is created because only two stages of the life cycle of an artefact can actually be observed: its production and its final deposition. What happened in between needs to be inferred.” (Bradley 1990, p.33)

Now I am back working on my PhD about the Mesolithic-Neolithic transition in Switzerland and the Jura Mountains. You can find out more about the site in Sutz-Lattrigen, the finds and the cup-marked stone in the Jahrbuch Archäologie Bern 2018. A short note also appeared in the Jahrbuch Archäologie Schweiz 101, 2018.

The unexpected little joys of lithic use wear analyses II

A little while ago I posted a photo of a crystal inclusion in a white flint bladelet. I promised to post some more, whenever I think of it. So here is another example of the beautiful things I have encountered doing the use wear analyses. This burnt flint bladelet, like the last example from Late Mesolithic layers at Lutter/St. Joseph, France, did not show any signs of use. However, the microscope does show beautifully the microfossils within the flint, or possibly radiolarite, out of which it was made. And, like the last example, this photo also shows the possibilities of the digital microscope I have been able to use for the study of the use wear analyses of Late Mesolithic artefacts from two Lutter/St. Joseph, France and Arconciel/La Souche, Switzerland.

The unexpected little joys of lithic use wear analyses I

Sometimes, when doing the microscopic analyses of use wear traces I come across fascinating things that have little to do with the actual use wear of the tools being studied. Instead they either provide something of a background to their natural origins or are just visually interesting. The digital microscope I have been using at the Dep. Of Geosciences at the Université de Fribourg, Switzerland has many technical possibilities. It allows me to document not only the use wear traces using a variety of photographic technologies. It also provides the opportunity to record composite photos such as this one of an otherwise not very interesting bladelet fragment from the site of Lutter/St. Joseph, in the French Alsace. I’ll try to publish a few more of such examples in the near future.

The alpine Mesolithic and the scrapers from Arconciel/La Souche. Oh, and much much more!

Way back in 2014 Laure Bassin and I presented the first results of our Gestures of TransitionsGestures of Transitions project at the MesoLife conference in Selva di Cadore in the beautiful Dolomites. Now these results have been published in a new volume of Preistoria Alpina. We could increase our results beyond those presented in the poster then and are pleased to be able to show a nice summary of our study of the scrapers from the Late Mesolithic layers at Arconciel/La Souche, Switzerland.

Scrapers are special at this site. Not only are many extremely small, an extraordinary large proportion of tools found at Arconciel/La Souche, over 50% of tools, were scrapers. So, curious about what we found out about these seemingly so insignificant little tools? You can download the paper here:

Cornelissen, M. and Bassin, L., 2016. Alpine raw materials and the production and use of scrapers at the Swiss Late Mesolithic site of Arconciel/La Souche, Preistoria Alpina 48, pp. 11-19

The well stratified rock shelter site of Arconciel/La Souche, Switzerland was repeatedly occupied between 7100 and 4900 cal BC. It lies in the Sarine river valley at the foot of the Prealps. This paper presents the first preliminary results of the study of the scrapers from this site. Of the chipped stone tool categories, scrapers are the most numerous found at Arconciel/La Souche. A combined technological and microscopic use wear study of the scrapers from three assemblages (ensemble
3, 4 and 5) has allowed us to examine the use and production of scrapers as well as how production and use relate to the various raw materials utilised at Arconciel/La Souche. We were able to show that although scraper morphology remained stable over time, there was a significant change in the relationship between raw materials and scraper production as well as the use of scrapers.
This research will be expanded to include other assemblages and chipped stone artefact categories from Arconciel/La Souche, but has already provided important new insights into artefact use-life in the still relatively poorly understood millennium leading up to the end of the Mesolithic on the Swiss Plateau and the nearby Prealps.

But there is even more! Preistoria Alpina has changed its set-up. The journal is now only available online and open-access. All posters from the MesoLife conference were published in this volume and are available! The papers presented one those hot summer days in the Dolomites have recently been published in volume 423 of Quaternary International. (With a little something about recent Mesolithic finds in the Swiss Alps by Thomas Reitmaier and myself.) That makes an amazing total of 48 articles on alpine Mesolithic!

These two volume show how vibrant the research of the Mesolithic in alpine and mountainous enviroments has become of late and will undoubtly be shown to be valuable additions to our knowledge of the Mesolithic in Europe. Hats off to the MesoLife organisers and editors of these two volumes!


The “Gestures of Transition” circus is still touring: This week at the Berner Zirkel!

About two weeks ago Laure Bassin and I presented our PhD research at the Universität Zürich. And that’s not it yet. We are very excited to annouce that this Thursday, December 8th, we will be talking (in German) about the “Gestures of Transitions” project at the Berner Zirkel für Ur- und Frühgeschichte. Samichlaus will be off again by then, but it will be a bag full of Mesoltihic goodies for everyone! Artefact biographies, use wear, chaînes opératoires, all based on our research on the lithic material from Arconciel/La Souche and Lutter/St-Joseph. In short the Mesolithic-Neolithic transition in Switzerland from a different point of view. The Berner Zirkel talks are aimed at the general public. Do look in if you are nearby. We would live to see you there!

Steingeschichten. Das Endmesolithikum zwischen Voralpen und Jura, geschrieben von den letzten Jäger- und Sammler/innen

Mit ihrer für das schweizerische Mittelland einzigartigen Stratigraphie ermöglicht es die Fundstelle Arconciel/La Souche (Kt. Freiburg) 2000 Jahre des Mesolithikums zu erforschen. Die ebenfalls vor wenigen Jahren untersuchte Fundstelle Lutter/St. Joseph (Elsass, FR) dient dabei als Vergleich. Im Nationalfonds-Projekt «Gestures of Transitions» wird mit neuen methodologischen Ansätzen das Ende des Mesolithikums im peri-alpinen Europa untersucht. Im Zentrum stehen Artefaktbiographien und die Kombination von technischen Untersuchungen und Gebrauchsspurenanalysen.

Wie wiederspiegeln sich die tiefgreifenden sozialen und wirtschaftlichen Veränderungen am Übergang zum Neolithikum in der Herstellung und im Gebrauch der Artefakte? Und erlauben sie es die Geschichten, welche sich an den zwei Orten abspielten, zu rekonstruieren?

The Berner Zirkel is also on Facebook with all sorts of new about archaeology in the canton of Berne and the region.

Cooking up a PhD

Last week I spend in a self-imposed writing retreat. I’ve found that this, if I am at the right stage in my work and feel like it (it can get lonely), gives my productivity a good boost. It works for me; I was able to get on really well with a large chapter of my PhD that I had been struggling with for a while. You might want to give it a try. The old advice of sleep well, exercise and eat well, however boring it may sound, is sound as well. But when you are writing you want to write and you don’t want to spend a lot of time cooking. Next to the cabin in which I spend my retreat grows a lovely fig tree and against all the odds I still got a handful of ripe figs every day all week. So, what better then to use them for an easy, tasty dinner?


We’re doing this the easy way, right? So I buy a ready made pizza base/dough. You can buy ones here (Switzerland) which are ca. 30cm diam. (ca. 3-320 g) and you just need to roll them out. The kind of cheese I use depends a bit what happens to be lying about in the fridge. What I think works best is a combination of a milder cheese, such as a vacherin, emmentaler, jongbelegen or mild cheddar, with something with a bit more taste, like an old gruyère, parmesan or something else, as long as it melts well.

You might not get figs anymore this time of year. It works a treat with pears as well!

It is a good snack for 2, perhaps with a small salad. Or it will make one hungry PhD student happy.


this year’s last figs

You need:

  • 1 pizza doug
  • ca. 4-5 ripe figs or a decent sized pear
  • 2 hands full of grated cheese (see above; you can never have enough cheese on anything, can you?)
  • a few slices of dry-cured ham (prosciutto di parma, jamon serrano, Schwarzwälder Schinken, something like that)
  • some chopped garlic, if you want
  • thyme
  • 1 tb olive oil

Now, get cookin’:

  • lay/roll out the pizza dough and prepare as described on the packaging
  • rub lightly with some oil and sprinkle over some salt if you want
  • spread the cheese over the base
  • sprinkle with a bit of thyme
  • tear up the ham and spread it over the cheese
  • cut the figs in quarters – or the pear in thin-ish slices – and place on the pizza

Bake at ca. 240ºc in the bottom half of the oven until the cheese has melted and the base is crisp, probably about 12 min (but you might want to look at the instructions on the dough packaging, though!).

Enjoy, and remember you can’t write on an empty stomach!

P.S. So, what food keeps you writing?
