Li Quan
During the Chinese Tang Dynasty (618–907 AD) there were some famous naval engagements, such as the Tang-Silla victory over the Korean kingdom of Baekje and Yamato Japanese forces in the Battle of Baekgang in 663. Tang Dynasty literature on naval warfare and ship design became more nuanced and complex. In his "Taipai Yinjing" (Canon of the White and Gloomy Planet of War) of 759 AD, Li Quan gave descriptions for several types of naval ships in his day (note: multiple-deck castle ships are referred to as tower ships below). Not represented here, of course, is the paddle-wheel crafts innovated by the Tang Prince Li Gao more than a decade later in 784 AD. Paddle-wheel craft would continue to hold an important place in the Chinese navy. Along with gunpowder bombs, paddle-wheel craft were a significant reason for the success in the later Song Dynasty naval victory of the Battle of Caishi in the year 1161 AD during the Jin–Song wars.
