.Spiral Staircase Muqarnas

Spiral Staircase Muqarnas

Muqarnas apparently have never been used as a ceiling treatment for spiral staircases. Once I determined the method it became clear that there are an unknown number of unique muqarnas spiral staircase ceiling types. The first I found was is in the background image above. It is the spiral analogue of the first tier of the ‘Ray’ type expansion of the muqarnas dome. Its animation is here:

The second spiral staircase ceiling form I developed is seen in the image at the top on the left. It is the spiral analogue of the second tier of the ‘Crescent’ type expansion of the muqarnas dome.

The third spiral staircase ceiling form I developed is seen in the image at the top on the right. It is the spiral analogue of the traditional central dome of the ‘Crescent’ type expansion of the muqarnas dome. Its animation is here:

The ‘tier’ is manifested in the diameter of the central column. The last example has a central diameter of zero because it is derived from the central traditional muqarnas dome. My own research into spiral staircase muqarnas ceilings has barely scratched the surface and has only established that a wide number of unique types are possible. It would make an interesting topic for a student to research.

I have developed an on-line presentation that describes the methods I use for creating various families of muqarnas forms, as well as some unique ones. It can be found at here. It is best viewed with Firefox.
