[11] Herbord reports that Otto, after periodically hiding in the city, began Christianization on November 1, after receiving security guarantees from Boleslav III.

Gold and silver "kraters," bull's horns decorated with precious stones that were drunk from or used as instruments, as well as swords, knives and furniture were dedicated to the god.

Ebo then goes on to describe how the priests of Wolin carted away the golden statue of Triglav to save it from destruction:[15]And when the pious Otto destroyed the temples and the images of the idols, the pagan priests stole the golden image of Triglav, which they worshipped as the most important, smuggled it out of the province and delivered it to the safekeeping of a widow who lived on a modest farm, where there was no danger that anybody would come in search of it.

Once they had taken this gift to her, she looked after it as if it were the apple of her eye and guarded that pagan idol in the following manner: after making a hole in the trunk of a large tree, she placed the image of Triglav therein, wrapped in a blanket and nobody was allowed to see it, much less touch it; only a small hole was left open in the trunk through which to insert the sacrifice and nobody entered that house unless it was to perform the rituals of the pagan sacrifices [...] And thus, Hermann bought himself a cap and a tunic in the Slavic style and, after many dangers along a difficult road, when he reached the house of that widow, declared that he had not long since succeeded in escaping from the tempestuous jaws of the sea thanks to the invocation of his god Triglav, and that he therefore wished to offer him the sacrifice promised for his salvation and that he had arrived there, led by him, following a miraculous order through unknown stretches of the road.

You may not see him nor touch him, but rather, prostrating yourself before the trunk, take note from a prudent distance of the small hole where you must place the sacrifice you wish to make.

What shall I say to my lord or who will believe that I was here, if I return empty-handed?” And looking around him, he saw Triglav’s saddle hanging nearby on the wall: this was extremely old and now served no purpose and, immediately rushing towards it, he tears the hapless trophy off the wall, hides it and, leaving in the early evening, he hurries to meet up with his lord and his men, tells them what he had done and shows Triglav’s saddle as proof of his loyalty.

After summoning and gathering the tribal chieftains and the elders, they demanded, by means of a solemn oath, that they abandon their cult to Triglav and that, once the image was broken, all of its gold would be used to redeem captives.

Soon afterwards, some Wolinians and Stettinians returned to their native faith,[17] as Ebo describes: In Wolin, the inhabitants, after burning idols during the first Christianization mission, began to create new statues decorated with gold and silver, and celebrated the feast of deities.

[18] He further states:Stettin, a big city, larger than Wollin, had three hills in its jurisdiction; the middle one of these, which was also the highest, was dedicated to Triglav, the most important god of the pagans.

About the idols, the priests said that their most important god had three heads because it ruled three kingdoms, namely, heaven, earth, and hell, and that its face was covered with a bandage so that it might ignore the sins of men as it did not see them and was silent.

[22] It is possible that the cult Triglav was mentioned by the 13th-century writer Henry of Antwerp [de], who was well informed about the battles for Brenna in the mid-12th century, according to whom a three-headed deity was worshipped in the stronghold, but he does not give its name.

A bronze horse, iron and decorative objects, including a lot of pottery, were discovered in the stronghold, indicating its importance and that an extensive religious cult may have been associated with it.

In doing so, he cites the pass of "Neptune"[c] worshipped in Wolin and links this to Slovenian traditions regarding Mount Triglav, a three-leveled idol from Zbruch, a Wolin's sacred spear attached to a pole, and an oak tree with a spring which,[e] according to Dynda, corresponds to the Norse Yggdrasil and the wells beneath it, and the hiding of the god's statue in the tree all of which are said to be connected to the Axis mundi.

Dynda proposes the following interpretations:[31] According to Henryk Lowmianski, the Triglav originated in Christianity – in the Middle Ages the Holy Trinity was depicted with three faces, which was later taken over by pagans in the form of a three-headed deity.
