The Dream Pool Essays or Dream Torrent Essays( Mèng Xī Bǐ Tán; Meng⁴ Hsi¹ Pi³-t'an²; 夢溪筆談/梦溪笔谈) was an extensive book written by the Han Chinese polymath, genius, scientist and statesman Shen Kuo (1031–1095) by 1088 AD, during the Song dynasty (960–1279) of China. Although Shen was previously a highly renowned government official and military general, he compiled this enormous written work while virtually isolated on his lavish garden estate near modern-day Zhenjiang, Jiangsu province. He named the book after the name he gave to his estate, the "Dream Brook".
