Here I show the seed patterns of the Nîmes labyrinth.
These have an unusual look. The half on this side of the axis (A) looks very similar as the seed pattern of the Walahfrid labyrinth (see below, related posts: Variants of the Same Seed Pattern / 1). We recognize the turns of the pathway in line with the axis and one half of the cross bar (a). The half on the opposite side of the axis, however, is rotated, split and separated into two parts (B). Thus we find the second half of the cross bar in vertical orientation (b). This seed pattern can be easily completed to the labyrinth using the well known method by connecting the two ends next to the center with an arc around the center and so forth.
Given what I have said about the transformation of the Nîmes labyrinth (see related posts: Five steps to the Nîmes labyrinth), we now can easily trace back these modifications to the seed pattern. First let us shift the outer turns of the pathway so that they align with the inner turns. By this, the half on the opposite side of the axis is unified. However it is still rotated and displaced at the inner side of the half this side of the axis. In a second step we therefore rotate it and shift it upwards. As a result we see the seed pattern that we know from the Walahfrid labyrinth.
