The element and substance Antimony has been known for thousands of years, some remains have even been traced back to as early as 4000 BCE. The name for the element comes from the Latin word antimonium which was derived from medieval Latin but has an unknown origin. While there is not a set date for when the element was very first discovered, the first individual to scientifically study antimony with information that was published was the French Chemist Nicolas Lemery. He published a textbook in 1675 describing methods of preparation for the element. In the history of the element, Antimony has served a great deal of diverse purposes, even being used as eye makeup in Ancient Egypt (The Editors of Encyclopedia Britannica, 2022).
