How was arsenic first discovered?
A more dangerous form of arsenic, called white arsenic, has also been long known. This was the trioxide, As2O3, and was a by-product of copper refining. When this was mixed with olive oil and heated it yielded arsenic metal itself. The discovery of the element arsenic is attributed to Albertus Magnus in the 1200s.

In the rest of Europe from the time of the Roman Empire through the Middle Ages and the Renaissance, arsenic was the king of poisons. Mineral forms of arsenic were known as early as the fourth century BC, but the German scholastic Albertus Magnus is usually accredited with the discovery of the element around 1250.
