17th century, but were always rare in the Arabic-speaking world. Such paintings are also mainly found in private palaces; examples in public buildings are rare though not unknown, in Iran there are even some in mosques. Eschewing figural representation, ornamentation in Islamic sacred architecture relies chiefly on arabesque and geometrical patterns. Early examples of non-figural representation in Islamic sacred architecture are found in the Umayyad Mosque of Damascus and the Dome of the Rock. The murals of the Dome of the Rock use crowns and jewels to symbolize earthly rulership and "otherworldly" plants as an invocation of the Quranic description of heaven. Similarly, the murals in the Umayyad Mosque of Damascus, which depict an idyllic cityscape are also meant to be an evocation of paradise without figural representation. The issue of aniconism has posed problems in the modern world, especially as technologies like television developed in the 20th century. For many years, Wahhabi clerics opposed the establishment of a television service in Saudi Arabia, as they believed it immoral to produce images of humans.

Today, the concept of an aniconic Islam coexists with a daily life for Muslims awash with images. TV stations and newspapers (which do present still and moving representations of living beings) have an exceptional impact on public opinion, sometimes, as in the case of Al Jazeera, with a global reach, beyond the Arabic speaking and Muslim audience. Portraits of secular and religious leaders are omnipresent on banknotes and coins, in streets and offices (e.g. presidents like Nasser and Mubarak, Arafat, al-Assad or Hezbollah's Nasrallah and Ayatollah Khomeini). Anthropomorphic statues in public places are to be found in most Muslim countries (Saddam Hussein's are infamous), as well as art schools training sculptors and painters. In the Egyptian countryside, it is fashionable to celebrate and advertise the returning of pilgrims from Mecca on the walls of their houses. The
