Remarkably, just one generation after the religion’s inception, Islamic civilization had produced a magnificent, if singular, monument. While the Dome of the Rock is considered an influential work, it bears little resemblance to the multitude of mosques created throughout the rest of the caliphate. It is important to point out that the Dome of the Rock is not a mosque. A more common plan, based on the house of the Prophet, was used for the vast majority of mosques throughout the Arab peninsula and the Maghreb. Perhaps the most remarkable of these is the Great Mosque of Córdoba (784-786) in Spain, which, like the Dome of the Rock, demonstrates an integration of the styles of the existing culture in which it was created.
