Emerald Tablet
Slightly different versions of the "Emerald Tablet" also appear in the "Kitāb Usṭuqus al-uss al-thānī" ("The Second Book of the Element of the Foundation", c. 850–950) attributed to Jabir ibn Hayyan, in the longer version of the "Sirr al-asrār" ("The Secret of Secrets", a tenth century compilation of earlier works that was falsely attributed to Aristotle), and in the Egyptian alchemist Ibn Umayl's (ca. 900 – 960) "Kitāb al-māʾ al-waraqī wa-l-arḍ al-najmiyya" ("Book of the Silvery Water and the Starry Earth").
