The aim of this paper is to show how sensory qualities were used to identify, observe, and describe plants in the sixteenth century. Mattioli's herbal is an example of Renaissance natural history, which was based on Dioscorides' classical text.
Each step of constructing a chapter of the herbal required a different approach to sensory qualities. The identification of the plants described by Dioscorides called for detailed philological work and a good knowledge of the meaning of each term used for tastes, smells or colours.
Descriptions were compared with living plants, while all plant parts and their properties had to be thoroughly examined. Taste was an important tool in establishing an affinity of a new plant with a plant from Dioscorides' text, because gustatory qualities were regarded as closely related to plant nature.
Visual qualities such as shape and colour were then especially useful in distinguishing varieties of particular plants.
