  Ge Hong 葛洪 (283–343 or 363 CE, a physician and Daoist from of the Eastern Jin (317–420 CE), was the first of several explicitly Daoist physicians to write about the practice of alchemy. He was the author of the Teachings of the Master Who Embraces Simplicity (Baopuzi 抱樸子). The Baopuzi consists of seventy chapters (pian 篇): twenty “Inner Chapters” (Baopuzi neipian 抱樸子内篇) and fifty “Outer Chapters” (Baopuzi waipian 抱樸子外篇). The two were effectively different books that were not combined under one title until a thousand years after Ge Hong’s time (Sivin1969, 389. For a partial translation of the waipian see Sailey 1978). Ge Hong was also the author of the Collected Life Stories of Immortals (Shen xian zhuan 神仙傳, trans. Campany 2002) and Biographies of Recluses (Yin yi zhuan 隱逸傳).
