A 14th century medical text

The aim of this article is to communicate what is said in Juan de Avinon's Galenic medicine treatise Sevillana Medicina (Seville, 1545) about bread and medicinal wine. Within the frame of traditional views taken from previous treatises, his own opinions are interesting and remarkable and they usually refer to what is produced and consumed in the city of Seville (Some occasional references to what is made in his birthplace, France, do not lack interest). Bread and medicinal wine are examined with regard to their nature, as well as to their effect on the process of digestion. At the same time, they are considered from the point of view of the appropriateness of their consumption according to the consumer's employment, especially with reference to bread.
