I was visiting Spain recently and while wandering about the Alhambra, it struck me how Roman Moorish Spain was...the tile mosaics, the arches and domes, the public bathhouses, the houses with the interior courtyards, etc. Religion aside, I think a Roman would have been much more at home in Granada than a contemporary Castillian city like Segovia. And even from a religious standpoint, Islam has far more in common with Christianity than with any Eastern religion.
Of course, given the heavy Hellenization of the Eastern Mediterranean from Alexander through to the Byzantine Empire, it's not surprising that the Arab culture was strongly influenced by Greece and Rome. In contrast, it had little contact with China and I think most of the cultural similarities between India and the Middle East derive from Islamic influence in India rather than the other way around. I think Arab culture should probably be viewed as a branch of Western Civilization rather than an Eastern Civilization.
