The ‘little sister’ of Zamora Cathedral: the collegiate church in Toro. ‘Little’ does not mean ‘inferior’. In fact, it is all the better for not having been rebuilt during the modern era, meaning it has retained its late Romanesque structure in its entirety.

Zamora Cathedral. Although it is not particularly large, it is the city’s largest and most important church. This 12th-century, three-nave basilica with a transept features an imposing west tower and a dome above the crossing of the naves. The choir is a later addition in the Late Gothic style.

It is now time for even more medieval impressions from León. The cathedral in León is arguably the finest example of French Gothic architecture in Spain.

We have surveyed the site at Ostrowite (northern Poland). It’s the perfect time of year for aerial photography herr. Plenty of cropmarks.

The fourth page of the comic is complete. The funeral of Judith of the Bohemian Haus of Přemysl. Bolesław Krzywousty was about six months old when his mother died. The marriage of duke Władysław Herman to Judith Maria of the Salian dynasty. Bolesław was about two years old.

The Church of Saint Gilles, with its magnificent portal, as we know it today, was not built for decades. The present building has destroyed most of older fundations.We do not know what the church looked like at the end of the 11th century. So I can use my imagination.

The year 1085. A Polish embassy send by Prince Władysław Herman is travelling to Saint Gilles in Provence. They are carrying a golden statuette of a boy, along with a request for the monastery to pray for the birth of the prince’s heir to the throne.

In 2022, I asked the AI model DALL-E to generate an image of an army led by the 12th-century Polish duke Bolesław Krzywousty fighting Pomeranians. It produced an image of 'knights' fighting Pomeranian dogs. In the 12th century, the Pomeranians were still only the inhabitants of Pomerania,

Dotarła właśnie w moje ręce książka "Bolesław Chrobry. Konteksty", nieco spóźniona na milenium koronacji władcy. Całkiem ładnie wydana, w dwóch wersjach językowych. To co mi się podoba, to różnorodność autorów pochodzących z różnych ośrodków badawczych, w tym zza granicy.

Wczoraj narysowałem ostatnią z 63 plansz komoksu o Bolesławie Krzywoustym. To jest miejsce, w którym kończy się narracja Galla Anonima, a ja na ostatnie 3 strony przechodzę na Herborda, by zrobić krótki epilog, związany z misją Ottona z Bambergu.

In the battle Comes Żelisław had his shield-holding hand cut off but immediately avenged the loss by manfully striking down his maimer. To honor him Duke Bolesław gave him a golden hand in place of the one of flash he had lost. (Gallus Anonymous Chronicle, beggining of the 12th century)

This ring pin was found during excavations in the 11th-century ring fort in Spycimierz, central Poland, in the 1960s. Unlike most Viking Age Scandinavian ring pins, it is made of iron, not bronze. However, it is decorated with thin bronze wire inlays. Iron pins were popular in 10th-13th c. PL.

The little Romanesque church in Inowłódz, central Poland, was probably built at the end of the 11th or beginning of the 12th century. Its contemporary, campanile-like western tower is the result of a reconstruction carried out in the 1930s for Ignacy Mościcki, the President of the Republic of Poland

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 #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.

Sampling in #Spycimierz, Central Poland. Spycimierz is an 11th–13th-century timber ring-fort that was converted into a motte-and-bailey castle in the 14th century. #archaeology #medievalsky

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.
