Theophrastus, Greek philosopher and botanist, (4th-3th century B.C.) studied the world of aromas with the keen eye of the observer driven by endless curiosity. He was the first scholar of odors: no one before him had treated the topic so systematically.

He was the first to explain the preparation of perfumes and their use, describing all the steps necessary to develop a harmonious fragrance, based on the perfect balance of every ingredient. He interrogated himself about the nature of odours, to understand its many mysteries. Theophrastus was the first to treat the theme of the composition of a perfume and its creation from an artistic point of view.
