Who was Al-Jaldaki?
Al-Jaldaki was one of the last and one of the greatest of medieval Islamic alchemists, he was the author of scientific works such as the al-Misbah fi Ilm al-Miftah and alchemical treatise The Proof Regarding Secrets of the Science of the Balance.
He was born in Jaldak, a district of Khorasan about 15 kilometers from Mashhad in Iran. In his writings he reveals that he spent seventeen years traveling through Iraq, Anatolia, Yemen, North Africa, and Syria, finally settling in Egypt where he composed many of his treatises.
