Emperor Taizong of Tang, Li Shimin, was an outstanding politician and literary figure of the Tang dynasty, best known for his political essays and poetry. He personally wrote the twelve chapters of Model for an Emperor, systematically outlining his approach to governing and emphasizing the importance of both benevolent rule and the rule of law. It became a model text for later emperors seeking to cultivate themselves and govern their realms. Few of his poems have survived, but works such as “A Poem Bestowed on Xiao Yu” and “Climbing the Three Terraces to Express My Aspirations” are profound and majestic, embodying both imperial grandeur and human concern. He was also a highly accomplished calligrapher. His Inscription on the Hot Springs, carved in running script, ushered in a new style of imperial calligraphy. Li Shimin championed “laying down arms and cultivating culture,” established the Hongwen Academy to nurture talent, and advanced the flourishing of Tang culture. His works reflect both exceptional vision and a broad-minded cultural outlook, providing the spiritual heart of the golden age known as the Reign of Zhenguan.
