2 Fold Spiral

4 Fold Spiral
 The religious significance can only be guessed, but it has been found on tombs, and possibly has a connection with the sun- the sun makes a spiral shape every three months in its travels. A triple spiral motif found on Celtic tombs is drawn unicursally (that is, in one continuous line), suggesting a cycle of rebirth or resurrection. (this hypothesis is bolstered by the fact that many of these appear to be deliberately placed where they catch the first rays of the sun on the solstice).
