By combining the artistic traditions of the previous eras and the new Islamic taste, the Samanians played a fundamental role in the creation of modern Iranian-Islamic art. The important question here is how much the role of different artistic traditions has been in this artistic creation. The basic point in answering this question is that due to the settlement of the Samanids at the meeting point of the Central Asian caravans that reached that region from China and India and the reference of their capital Bukhara to the Assembly of Great Religions by some Islamic writers, it had a great potential for internationalization which has also come to the fore in the field of art. Therefore, Samanian art can be seen as the arena of confrontation between different Zoroastrian, Buddhist, Taoist and Islamic cultures and religions, and in the end, under the influence of the Iranian ambition of the Samanids and the power of the Islamic religion, only the Iranian and Islamic elements remained and continued. Since the Islamic or even Zoroastrian elements of Samanian art (such as Chahartaqhi design, Sakanj, etc.) are more or less known; With the aim of identifying the imported Buddhist and Taoist elements affecting the form and decorative motifs of Samanid architecture, this research examines several prominent Samanid buildings, including Amir Ismail’s tomb, Tim’s tomb, and the Nine-Dome Mosque. Therefore, the present research, by using the descriptive method and analytical comparative approach and the method of collecting documentary and electronic information, intends to answer this central question that apart from Zoroastrian and Islamic elements, which Buddhist and Taoist elements inspired the form and decorative motifs of Samanian period architecture? The results of the research show that Buddhist and Taoist art entered eastern Iran through exchanges on the Silk Road, and finally by combining the artistic elements of these religions such as the lotus flower, Dharmacakra and Chinese crucifix with Iranian and Islamic elements, the first artistic and decorative style of Iran was born in It has become an Islamic era.
