In the "Annals of the Later Han" and the "Mouzi lihuo lun", Emperor Ming of Han (r. 58-75 C.E.) was said to have dreamed of a spirit, who had a "gold body" and a head which emitted "rays of light". His advisers identified the spirit as Buddha, who was supposed to have the power of flight. The emperor then ordered a delegation (led by Zhang Qian ) to go west looking for the Buddha's teachings. The envoys returned, bringing with them the two Indian monks Kasyapa Matanga and Dharmaratna, and brought them back to China along with the sutra. When they reached the Chinese capital of Luoyang, the emperor had the White Horse Temple built for them.
