The relaciones de fiesta constitute a significant portion, over the past decades object of critical attention by scholars of various European and American universities, of that production generally identified as paraliterary, and therefore marginalized. The discovery and subsequent exploitation of these texts is based on the fact that they are real reservoirs from which elements of scientific interest from multiple perspectives can be drawn: for the historian of literature, culture, religious beliefs, popular traditions, history of art, of the editions etc. The essay in question analyzes the Sucinta descripcion de los regozijos (perhaps of Ignacio Paliacho, author of the loa included in the text), published in Cagliari in 1722 for the wedding of Prince Carlo Emanuele. Preliminarily, thanks to investigations conducted in the Archives of State and the Town Council of Cagliari, data relative to the typology of the feasts and of the occasions which determined them, are provided, contributing,in this way, to the positioning of such materials of local origin, in the wider context mentioned above.
