While the subject matter of these paintings was borrowed from other cultures, Timurid wall paintings were eventually refined into their own, unique style. Mongol artistic traditions were not entirely phased out, as the highly stylized depictions of human figures seen in 15th century Timurid art are derived from this culture. Sultan Husayn Bayqara reign saw a further rise in the arts. He was renowned as a benefactor and patron of learning in his kingdom. Sultan Husayn built numerous structures including a famous school. He has been described as "the quintessential Timurid ruler of the later period in Transoxiana" and his sophisticated court and generous artistic patronage was a source of admiration, particularly from his cousin, Babur of Mughal India.
