I'm always a little worried when I try to introduce myself as an archaeologist of the early Middle Ages, because the early Middle Ages end in Polish historiography around 1250.
We only have the Early and Late Middle Ages. We've lost the High Middle Ages somewhere.

I am experimenting with AI models that generate films to find out to what extent they can be used to create visualisations of the past. Visualisations will be as accurate as possible in terms of material culture. I usually start with a hand drawing.

This experiment is based on 1960s archaeological documentation from research conducted in #Spycimierz. Five pictures of one of the trench walls were preserved in the archives.

This #NanoBananaPro is like the story of the man who asked goldfish for the biggest penis in the world and was turned into a blue whale. I asked it to edit a photo, and it added mountains to the background. But this photo was taken in Spycimierz in the Warta Valley in the Lowlands.

After a supplementary survey based on sampling with a motor auger, we can conclude that the ring-fort in #Spycimierz was not built on elevated terrain, which was common for most early medieval strongholds in lowland Poland. It was built on the plain bottom of the river valley.

Spycimierz is an 11th–13th-century timber ring-fort that was converted into a motte-and-bailey castle in the 14th century.

I'm still working on my comic book about Bolesław Krzywousty and the conquest of Pomerania. This time it's a scene from his palace with mural paintings depicting scenes from the Piast dynastic legend. It is slightly based on the Premyslid legend depicted in the round church in Znojmo.

Gniezno Cathedral: Built in the 14th century on the site of a much smaller, older #Romanesque church. It was the seat of the #medieval Archdiocese of #Poland and the country's principal church.
It was reconstructed in the Baroque style in the 17th century after being destroyed by fire in 1760.

Although the excavations in Ostrowite are officially finished for this year, that doesn't mean that our research is over. We still plan to drill a little more. Stay in touch!

Today, our excavation team found itself at the heart of events connected with the Russian drone attack on Poland. Fortunately, we didn't encounter any drones, but we could observe NATO air force activity over our trench.

Do you remember the skeleton that emerged when the topsoil was removed? We now know a little more about this burial.
Please note that photos of the skeleton will appear below. If you are easily upset, now would be a good time to stop reading.

The state of preservation of the archaeological objects in Ostrowite: the photo shows a fragment of a human skull. Apart from a piece of the right femur, this is all that remains of a #medieval (11th-13th c) burial that was destroyed by agricultural work.

During the exploration of the cultural layer, bronze braided circles were found. They are likely to have been part of a larger ornament. The chronology is unknown. It is probably from the early Iron Age.
