The teaching of languages and the protection of the artistic and musical heritage aims first and foremost to provide students with the necessary information to read and decode the image of a work of art at whatever time and place it was created. For this to happen, the historical, political and cultural context of the work and the author must first be reconstructed. This is done through the selection of case studies of works of various kinds and genres produced between the 4th century BC and contemporary times. Each image, in fact, is endowed with its own linguistic code, which, once identified, allows comprehension. Secondly, the artistic and musical heritage has its own specific technical language, the acquisition of which is important for translating the image of the work itself into words. This language must be available in the student's skill set whenever he or she accesses a work of art and has to decode it in words. Moreover, written texts, such as the label of the work, its historical quotations and the sources it draws on, are attached to the works, of which the student must be aware, because they are in constant dialogue with the image. Then it is necessary to define what is meant by artistic and cultural heritage according to the relevant legislation, which adopts its own specific language. Then it is necessary to define what is meant by artistic and cultural heritage according to the reference legislation, which adopts its own specific language. Finally, it is essential to define what is meant by protection, as conceived by the reference legislation and the most important historical practices. At the end, the student will be able to master an adequate technical language in relation to artistic and musical heritage and know how to use it to decode images related to it.
