Equally irregular are the Riwaks, or porches, surrounding the hypaethral court.

Perhaps, therefore, they were hypaethral, like the temples of the Greeks.

The hypaethral is decastyle in both front and rear porticoes.

Nor did the Romans construct hypaethral or uncovered temples with internal columns, like the Greeks.

The four Riwaks, or porches, of the Madinah Mosque open upon a hypaethral court of parallelogramic shape.
