This project consists of a program to re-identify the sources of the romantic contexts present in compositions by Portuguese authors listed by Carolina Michaëlis de Vasconcelos, as well as a critical examination of these settings in their new literary context. It therefore aims to enhance the reinterpretation of the aforementioned works and, to that extent, rebalance the connections between canonical literature and traditional literature. At the same time, it makes a decisive contribution to the knowledge of the old bookseller in Portugal.
