Descubrimiento de azufre First used at least 4,000 years ago. According to the Ebers Papyrus, a sulfur ointment was used in ancient Egypt to treat granular eyelids. Designated as one of the two elements of which all metals are composed in the sulfur-mercury theory of metals, first described in pseudo-Apollonius of Tyana's Sirr al-khaliqa ('Secret of Creation') and in the works attributed to Jabir ibn Hayyan (both 8th or 9th century).
