Emperor Guangwu (13 January 5 BC  29 March 57), born Liu Xiu, was an emperor of the Chinese Han Dynasty, restorer of the dynasty in AD 25 and thus founder of the Later Han or Eastern Han (the restored Han Dynasty). He ruled over parts of China at first, and through suppression and conquest of regional warlords, the whole of China was consolidated by the time of his death in 57. Yan Liben (WadeGiles: Yen Li-pen, c. 600-673), formally Baron Wenzhen of Boling, was a Chinese painter and government official of the early Tang Dynasty. His notable works include the Thirteen Emperors Scroll and Northern Qi Scholars Collating Classic Texts. He also painted the Portraits at Lingyan Pavilion, under Emperor Taizong of Tang, commissioned in 643 to commemorate 24 of the greatest contributors to Emperor Taizong's reign, as well as 18 portraits commemorating the 18 great scholars who served Emperor Taizong when he was the Prince of Qin. Yan's paintings included painted portraits of various Chinese emperors from the Han Dynasty (202 BC-220 AD) up until the Sui Dynasty (581-618) period.
