Islam's prohibition against idols adversely effected sculpture and kept this Iranian art in the dark for 13 centuries. The glorious age of sculpture in Iran ended with the Arab dominance. During this long era the only sculptor to be mentioned was Farhad the Mountain Carver and even he is buried under a halo of legends. In 2009, a sculpture titled Persepolis was sold at a Christies' auction for $2.84 million. It was the work of the father of modern Iranian sculpture, Parviz Tanavoli, whose works are in the permanent collections of museums around the world. The Iranian sculptor, painter, scholar and collector Parviz Tanavoli succeeded in reviving Iranian sculpture after 13 centuries of silence.
