“…On the other extreme is the circle. This is the perfect shape. All its points are equal distance from the center – which represents equality and perfection. …
So, as a human (square) strives to be more godly and seeks perfection, he (or she) strives to emulate a circle. Now in your minds eye, imagine a square turning into a circle. The corners begin to get rounded more and more. Perhaps the square begins to turn and with every turn it’s corners get more and more rounded – one degree at a time. The square will begin to resemble an octagon and then eventually a circle.
This transition can be seen in old minarets which start with a square/rectangular base. They then transition into an octagon in their trunk and are topped off by a domed top which is semi-circle. Thus the masjid or mosque turns more and more godly as it reaches higher and higher into the heavens.
This transition of shapes and the meaning behind them gives a new perspective of looking at Islamic art and architecture.“
