Chinese calligraphy was introduced to Korea as early as the 2nd or 3rd century CE, and became popular in the 7th century. In the 8th century, Kim Saeng became known as the earliest Korean calligraphic master, producing work that was compared with that of master Chinese calligrapher Wang Xizhi.[3] In the 9th century, poet Choe Chiwon became known for his calligraphy both in his home country Silla and in the Tang Dynasty.[4]
