> is the dome of the rock an innovation too to you?
Yes, actually. It is one of the prime examples of Umayyad architecture, aside from the Great Mosque of Damascus. It stemmed a good bit from the Byzantine architecture of the time (which also cross-pollinated with Persian architecture) while innovating in its style in many ways to achieve a uniquely Islamic aesthetic. It helped set the ground for the monumental calligraphic style and motifs we're familiar with today in Islamic art.
