A new cable with a strong Celtic appearance. I found it on the net, it's called a Frode knot. A part of Viking braid cables. I found a book, Viking Patterns for Knitting, so i ordered it immediately:) It will be an inspiration in my future freeform. Since i had no pattern of the knot, i had to analyze it from the picture, it took me about 3 hours to figure it out. I'm very glad with the result!
