One of the earliest known references to lodestone's magnetic properties was made by 6th century BC Greek philosopher Thales of Miletus,[1] whom the ancient Greeks credited with discovering lodestone's attraction to iron and other lodestones.[2] The name magnet may come from lodestones found in Magnesia, Anatolia.[3] The ancient Indian medical text Sushruta Samhita describes using magnetic properties of the lodestone to remove arrows embedded in a person's body.[citation needed]
