Ibn Umayl
Muḥammad ibn Umayl al-Tamīmī (Arabic: ), known in Latin as Senior Zadith, was an Egyptian alchemist who lived from c. 900 to c. 960 AD. Very little is known about his life. A Vatican Library catalogue lists one manuscript with the "nisba" al-Andalusī, suggesting a connection to Islamic Spain, but his writings suggest he mostly lived and worked in Egypt. He also visited North Africa and Iraq. He seems to have led an introverted life style, which he recommended to others in his writings. Statements in his writings, comparing the Alchemical oven with Egyptian temples suggest that  he might have lived for some time in Akhmim, the former centre of Alchemy. He also quoted alchemists that had lived in Egypt: Zosimos of Panopolis and Dhul-Nun al-Misri. In later European literature, ibn Umayl became known by a number of names: his title Sheikh become 'senior' by translation into Latin, the honorific "al-sadik" rendered phonetically as 'Zadith' and 'ibn Umail' becoming by erroneous translation 'filius Hamuel', 'ben Hamuel' or 'Hamuelis'. Historical value. The "Silvery Water" was particularly valuable to Stapleton, Lewis, and Sherwood Taylor, who showed that of some of Umail's "Sayings of Hermes" came  from Greek originals. Also its numerous quotations from earlier alchemical authors allowed, for example, Stapleton to provenance the "Turba Philosophorum" as being Arabic in origin, and Plessner to date the "Turba Philosophorum" to ca. 900 AD. Ibn Umayl's works contain an early commentary on the "Emerald Tablet" (a short and compact text attributed to Hermes Trismegistus), as well as a number of other Hermetic fragments. Symbolic alchemist. Ibn Umayl was a mystical and symbolic alchemist. He saw himself as following his “predecessors among the sages of Islam” in rejecting alchemists who take their subject literally. Although such experimenters discovered  the sciences of metallurgy and chemistry, Ibn Umayl felt the symbolic meaning of alchemy is the precious goal that is tragically overlooked. He wrote: “Eggs are only used as an analogy... the philosophers … wrote many books on such things as eggs, hair, the biles, milk, semen, claws, salt, sulphur, iron, copper, silver, mercury, gold and all the various animals and plants … But then people would copy and circulate these books according to the apparent meaning of these things, and waste their possessions and ruin their souls” "The Pure Pearl" chap. 1. Moreover, he wrote a "Book of the Explanation of  the Symbols", there emphasizing that the sages spoke "a language in symbols" and that they "would not reveal it [the secret of the stone] except with symbols". In this book, he gives a huge list of names for the stone, the water, etc. thus referring to one inner mystery or religious experience, which - in contrast to an allegory - cannot be fully explained. For all his devotion to Greek alchemy, Ibn Umayl wrote as a Muslim, frequently mentioning his religion, explaining his ideas "for all our brothers who are pious Muslims" and quoting verses from the Quran. The interpreter. Ibn  Umail presented himself as an interpreter of mysterious symbols. He set his treatise "Silvery Water" in an Egyptian temple "Sidr wa-Abu Sîr", the Prison of Yasuf, where Joseph learned how to interpret the dreams of the Pharaoh. (Koran: 12 Yusuf and Genesis: 4) "... none of those people who are famous for their wisdom could explain a word of what the philosophers said. In their books they only continue using the same terms that we find in the sages ... What is necessary, if I am a sage to whom secrets have been revealed, and if I have learned the symbolic  meanings, is that I explain the mysteries of the sages." Ibn Umails "Book of the Explanation of Symbols (Ḥall ar-Rumūz)" can be considered as a summary of his "Silvery Water and Starry Earth", giving a "unified synthesis of Ibn Umail's earlier works". Modern psychological interpretations. The psychologist CG Jung recognized in ibn Umayl’s story the ability to bring self-realization to a soul by interpreting dreams, and from the 1940s onwards focused his work on alchemy. In continuation of Jung's approach towards alchemy, the psychologist Theodor Abt states that Ibn Umail's "Book of the Silvery  Water and the Starry Earth" gives a description of a process of distillation, which is meant as image for a process of "continuous pondering over the different symbols", creating thus consciousness (symbolised by 'light', 'gold') out of the reality of matter, nature and body ('starry earth'). This shows that the "alchemical process is in fact entirely a psychological work that is based on dealing with concrete matter and the bodily reality."
