The Norse loved alliteration, it is extremely common in Norse poetry and sagas.
indeed! even Tolkien was a huge fan of this! he has a very sizable body of work written in alliterative verse including re-tellings of the Völsungasaga and Atlakviða in modern english but retaining the same style as the original.
The repetition of one or multiple sounds across a sentence. One example is "Sally sold sea shells by the seashore".
The alliteration ties back to the older forms of Germanic poetry, which had little to do with rhyming and a lot to do with alliteration and with clever ways of renaming things. Try googling "alliterative verse."
This is an extremely uncommon sentence, though. As uncommon as its English translation.
