This publication, coordinated by Dr. Antoni Rossell and Dr. Hélène Rufat, presents the figure of Frédéric Mistral, Nobel laureate in Literature (1904), leader in the rehabilitation of the Occitan language and beating heart of relations with the Catalan intellectual world. His rôle was fundamental for the cultural milieu of Catalonia, a fact reflected in the wide range of written testimonials preserved in Catalan institutions. This book provides a taste of the rich documentation available in the Biblioteca de Catalunya in Barcelona and the Biblioteca Museu Víctor Balaguer in Vilanova i la Geltrú. The book contains interviews with specialists in the field who provide a multifaceted vision of Mistral; among them, Jaume Figueras i Trull, Manuel Jorba, Ramon Panyella, Montserrat Comas, August Rafanell, Vinyet Panyella and Lluïsa Julià. The volume encompasses musical performances by the group Mirabèl, alongside readings of texts and poems by Carlos Heusch, Ramon Panyella, August Rafanell, Rafèu Sichel-Bazin, Jaume Figueras I Trull, Jaume Clarà and Margalida Tomàs. The book concludes with an extensive bibliography and a list of digital resources that contribute to research and understanding of the Mistralian œuvre within the Catalan context.
