Agathodaimon
Additional recommended knowledgeHe described the 'fiery poison' as being formed when a certain mineral (most probably realgar or orpiment) was fused with natron (naturally occurring sodium carbonate), and that dissolved in water to give a clear solution. He also wrote of how, when he placed a fragment of copper into the solution, the copper turned a deep green hue, lending further validity to the suggestion that orpiment or realgar was used, as they are both arsenic ores, and this would be the hue achieved from the copper after it had been placed in the arsenic trioxide had the substance formed been copper arsenite.[2] Agathodaimon's discoveries exist as part of the foundations for later use of poison, as arsenic and related substances were used regularly in later centuries as means of poisoning and murder. Since the only records of his existence are references in later works, he may be apocryphal, but since the practice of alchemy itself began to decline around the time he is believed to have lived, and it may be that much of his writing was lost.[1] Some of the writings of other alchemists on alchemy of the time were preserved and saved by a sect of dissident Christians, who called themselves the Nestorians, and who were able to escape to Persia at around 400.[3] This information that was gathered by the Nestorians eventually passed on to the Arabs, and this in part contributed to the flourishing of alchemy in that region and in their hands; the modern English word "alchemy" comes from the Arabic language, and many of the foundations for alchemy in Western nations were laid by the Arabs.[4][2] See also
