The Romanesque building was supplemented in the second half of the 13th century by the magnificent Pórtico de la Majestad portal. The first two pictures show the Romanesque north portal, while the rest show the Portico de la Majestat.

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.

The best-preserved Romanesque feature, apart from the interior, is the south façade with its imposing portal – the Puerta del Obispo (Bishop’s Portal).

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.

The funniest thing is those tall, screen-like gables, behind which lie relatively flat, low roofs. The gables would have had to be like those in France, but there was no need for such steep roofs.

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.

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.

which is now northern Poland. The model was unable to understand the context of medieval Pomerania and was unaware of the Pomeranian Wars in 12th C. I was curious to know if this had changed after 4 years of developing such models. So I asked Nanobanana to generate a picture using a similar prompt.

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.

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)

The pin spent over 60 years in storage. After spending over half a century in storage, it didn't look particularly good. The bronze inlays had oxidised and turned green. But now, after conservation, it has regained its former glory.

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.

On the absis wall, you can easily find a stone with a carved cross, which is part of a 12th- or 13th-century grave slab. Before the entrance is a baptismal font, which is also likely to date from the 12th or 13th century.

Mościcki enjoyed spending time in the area. He had a country presidential residence nearby in Spała. The tower was certainly less impressive before the reconstruction work.

Jerzy Sikora @jsikora.bsky.social · 17/01/2026

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

This is the second attempt to Grok, this time with a prompt. Creepy.

Jerzy Sikora @jsikora.bsky.social · 01/01/2026

The second attempt was made using Grok. Initially, I didn't prompt it because I couldn't find how to switch off the automatic generation of videos. This was strange.

Then I used Google Gemini's #Veo feature to animate the picture. The mourner was supposed to place a sword on the coffin. The model also automatically generated a speech of the mourner: 'May this sword guard you on your journey into the Otherworld', which is... interesting.

As a result, I was able to create an orthomosaic of the wall. For comparison, here is an orthomosaic of our trench from 2022, in which the stratigraphy situation is quite similar.

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. #Archaeology

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.
