, 2023 This volume explores the concept of “transition” across time and space, from the Middle Ages to the 19th, 20th, and 21st centuries in Spain and Latin America. It examines various types of transition—religious, cognitive, linguistic, literary, or identity-related—while questioning whether these transitions have been successfully achieved.
