There's no historical justification for combining popular labyrinths of different historical periods, but some combinations look nicely decorative so I did it anyway.
Two identical square Cretan labyrinths rotated 180 deg with respect to eachother with their entrance/exit points joined. The spectrum colouration starts in the centre of one, flows out, flows into the other labyrinth and ends in the centre of it. I'm sure one could come with some spiritual story of it representing a closed nature of continual waxing & waning. More prosaically, it reminds me myself of some complex fluid flow between a source & a sink.
This is an alternative way of joining two square Cretan labyrinths, having one being the mirror image of the other. It has the advantage of needing an offset in the middle to join them so it is regularly space filling but, in my opinion, the reversal of curvature in the middle interrupts it making it less pleasing than the rotational symmetric one.
Another alternative, using a ring (drawn here as a thin rectangle) instead of a kink to join two Cretans. It has the advantages both maintaining curvature and being space filling but has the aesthetic disadvantages of being essentially an arbitrary bodge and it not technically being a labyrinth any more because it has a branch in its path. As both branches are the same length, the colouring joins up seamlessly though.
Making the path & wall of equal width so that it the pattern fits a regular grid highlights the space filling property.
Unfortunately four Cretan labyrinths don't fit together as well as 2 do. I've coloured it with the spectrum starting simultaneously from the centres of two of the component labyrinths and ending in the centres of other two.
A nice solution to the sparse looking gap in the centre of 4 joined Cretans is to fill it with a looped Roman labyrinth.
The same path as the previous combination but with the spectrum starting from all four Cretan labyrinths simultaneously and ending converged in the central Roman labyrinth giving the colouration a 90 deg rotational symmetry in addition to the 180 degree one.
