To będzie olbrzymie poświęcenie ze strony Prezesa, żeby wejść w koalicję z Braunem, ale czego się nie robi dla ratowania Ojczyzny przed Tuskiem i Niemcami.

Przede mna jeszcze znalezienie kogoś, kto chciałby to wydać w formie takiej, jaką sobie wymarzyłem, a więc z obszerną częścią opisową, zawierającą zdjęcia zabytków i mapy, dające archeologiczny i historyczny kontekst całej opowieści.
Mam pewne pomysły.

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.

Panie Wojciechu, nie wczesnośredniowieczne. To tzw. High Middle Ages. W większości europejskich podziałów chronologicznych mieszczą się zwykle między XI a końcem XIII lub połową XIV wieku.
Oczywiście fabuła to fikcja, ale sam komiks fajny. Czekam właśnie na dostarczenie 2 tomu.

Now you know who was the inspiration for Jaime Lannister from Game of Thrones.

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.

We had a beautiful sunny day today. Ideal for taking pictures.

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.

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

Is there no 'Show' option? You probably have some restrictions in your account settings.

As you can see, it is not very accurate in terms of material culture.

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

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.

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.

On the left is my drawing of Bolesław III in Wawel Castle in Cracow at the beginning of the 12th century, based on archaeological research. On the right is a reworked picture by #nanobanana.

Realizujemy program, który zmierza do publikacji wyników badań archeologicznych grodziska w Spycimierzu. Program jest dofinansowany z środków Ministerstwa Kuktury i Dziedzictwa Narodowego.
Przy okazji powstał ten film.

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.

I put it into the photogrammetry software and created a 3D model. I scaled it based on the scale visible in the pictures.

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.

So I asked it to bring the sky with clouds back. Then it generated a random sky with clouds.
I probably just don't understand how to use it.

I asked it to erase the mountains in the background, but it erased the whole background.
