An element of Islamic art usually found decorating the walls and window screens of mosques and Muslim homes and buildings, the arabesque is an elaborate application of repeating geometric forms that often echo the forms of plants, shapes and sometimes animals. The choice of which geometric forms are to be used and how they are to be formatted is based upon the Islamic view of the world. To Muslims, these forms, taken together, constitute an infinite pattern that extends beyond the visible material world. To many in the Islamic world, they in fact symbolize the infinite, and therefore uncentralized, nature of the creation of the one God ('Allah' in Arabic). Furthermore, the Islamic Arabesque artist conveys a definite spirituality without the iconography of Christian art. Arabesque is used in mosques and building around the Muslim world, and it is a way of decorating using beautiful, embellishing and repetitive Islamic art instead of using pictures of humans and animals (which is Haram or forbidden in Islam).
