The recorded history of art in Bangladesh can be traced to the 3rd century BCE, when terracotta sculptures were made in the region. In classical antiquity, a notable school of sculptural Hindu, Jain and Buddhist art developed in the Pala Empire and the Sena dynasty. Islamic art evolved since the 14th century. The architecture of the Bengal Sultanate saw a distinct style of domed mosques with complex niche pillars that had no minarets. Mughal Bengal's most celebrated artistic tradition was the weaving of Jamdani motifs on fine muslin, which is now classified by UNESCO as an intangible cultural heritage. Jamdani motifs were similar to Iranian textile art (buta motifs) and Western textile art (paisley). The Jamdani weavers in Dhaka received imperial patronage. Ivory and brass were also widely used in Mughal art. Pottery is widely used in Bengali culture.
