## Appendix A. Muqarnas Questionnaire

This questionnaire lists aspects of muqarnas
design that I have found useful to examine for the
vaults considered in this study. It can easily be
extended, leading perhaps to a typology of muqarnases.
In constructing it I considered, among others, the
portals of the
Jâmi` al-Taubah, of 629–32/1231–35, the
Bîmâristân al-Qaymarî, of 654/1256,
and the Madrasah al-Zahirîyah, of 676/1277–78.^{1}

How deep is the muqarnas vault compared to its width?

Does the muqarnas spring square or from corner brackets, and
does it rest on a cornice?

How are the back corners handled?

How many tiers are there? Are the cells the same height in
the various tiers? the same depth?

What is the geometry as seen from beneath? Does it change
(*e.g.*, from eight radial axes, or some multiple, to ten
or twelve)?^{2}

Are there rolled square brackets?

Are there branched brackets?

Are there gored conches?

Are the corners developed into recessed domelets, and if so
how many of them? Are there “flues”, or
vertical sequences of recessed cells (see the Madrasah al-Sâhibah)?

Is the top of the vault a gored semidome or a smooth
semidome decorated with geometric ornament?

Does the exterior arch profile reflect the profile of the
muqarnas or is it a smooth pointed arch? Is it enclosed
within another arch or frame?

Is there a decorative archivolt?

1. For a
broader typology of muqarnases see Allen, *Five Essays,*
pp. 85–90.

2. While some of his conclusions are
dubious, Michel Écochard's *Filiation de monuments
grecs, byzantins et islamiques: une question de
géométrie,*
illustrates admirably the relations of various muqarnas
geometries.
