One of the primary pioneering figure in the founding of pharmacy practices is Pedanios Dioscorides who wrote a five-volume book in his native Greek, but known in Western Europe more often by its Latin title De Materia Medica or ("On Medical Material"), which became the precursor to all modern pharmacopeias. His book is the prime historical source of information about the medicines used by the Greeks, Romans, and other cultures of antiquity.
