It has been a while since my last blog. The resason is that I am reflecting over the westcoast versus east (rock carvings), and will write some about the differences soon!
As before mentioned, I went to the workseminar in Tanum in the end of july. It was wonderful as always, because the lectures were interesting, and there were other rock art enthusiasts. During the last years it has been a wish for Tanums Hällristningsmuseum to document the panel Bro Utmark. It is a very large and steep panel, divided into smaller panels. It is situated in the middle of the forest, and is therefore overrunned by water, even after long dry periods. This is due to a lot of moss growing around the edges of the panel – it holds huge amounts of water! BUT this year we managed to fulfill the dream 🙂 We were four groups working there, and we got to work a little further away from the other groups. More pictures will follow soon 😉
Now an english summary is available for download. The complete thesis is also available for download, but at the moment it is only available in danish. Hopefully it will be translated into english in the future. Both PDF-files are available in the menu “Projects – MA thesis”. At the same site, you can also have a look at the animations of four of my 3D-models, which was created with photogrammetry. I will soon update the site “photogrammetry”, so you can get knowledge about the method, but you can also read a thorough description of the method in the thesis + other digital methods as laserscanning, white-light scanning, RTI and Structure from Motion.
This is the cover of my thesis. It is a small part of my favorite panel: “the shoemaker from Backa Brastad” (Brastad 1). In fact this panel was object to possibly the oldest documentation in the world, of rock art. This early documentation was created in 1627 by Peder Alfsøn. You may read more about this and other things in my thesis (photo: Mette Rabitz).
It has been a while, since my last post. The time runs so fast, every day takes the other! If it was possible, I would wish the day had more hours! Time runs so fast, and I am also busy with some articles about digital documentation and photogrammetry, and preparation for a coming lecture. But I am definitely not complaining! It is nice to have something to do, and being outside all day, and experience a lot of interesting stuff 🙂
Recently, we worked with Sven Gunnar Broström and Kenneth Ihrestam. We cleaned the panels, and they documented it, with the tracing method. For a thorough description of the method, take a look at the menu documentation – tracing, which has been updated!
A week ago, I arrived in Norrköping, which is part of “Östra Götalands län“, which is situated on the eastern coast of Sweden. In the next months, I will participate in fieldwork related to the many rock carvings of the area. For more information of the work, please visit my projectleaders blog: www.hällristningar.se Recently there has been an experiment with cleaning the rock surface with “ultra clean” water, which is water cleansed from mineral, salt and chalk. You may also see more information about this, on the before mentioned link 🙂
I think it is a very interesting experience for me, to work with the carvings of Norrköping. First of all the motives differ slightly from the ones from the westcoast (Västra Götalands län). Previously I have only experience with the rock carvings of the westcoast, so it is quite new to me, but very useful for me to get to work in a new area. Another challenging, but interesting experience is that the rock carvings in Norrköping are carved on slate. On the westcoast the dominating rock is granite. Some days ago, I showed the rest of the team how to document with the rubbing method. It was somehow a little different to rub on a slate surface, cause the surface is very uneven, and it seems that one has to press the carbon much harder, than if one was documenting a granite surface.
Some weeks ago, I got an opportunity to teach future archaeologists from University of Copenhagen in documentation of rock carvings. I started with a lecture about digital documentation of rock carvings. The lecture was followed some weeks later, with a practical lesson, which took place at “The land of legends” in Lejre near Roskilde, Denmark. It is an experimental centre with artificially created villages from different periods of the prehistory. A lot of experiments are taking place in the centre, in order to create an explanation and understanding of the prehistory. The centre also include three boulders with artificial rock carvings, which have been “carved” with modern drilling tools. So my teaching in documentation was not optimal, since the situation was not realistic. -The students were not able to get knowledge of the feeling of real carvings, but they got an impression of how to document with the rubbing-method.

After the demonstration of the method, my intention was to let the students try to do a rubbing, but it started to rain 🙁 So we went inside, and I gave a small lecture about the rubbing-method instead.
