The fascination that the work of Gaudí arouses is due in large part to the enigmatic symbolism of its forms, full of mystical and philosophical significance that is sometimes difficult for observers to perceive, but which becomes clearer when analysed in the light of certain very influential currents of ideas in the art of the nineteenth and early twentieth centuries. Based on the study of Casa Bellesguard and the Temple of the Sagrada Família, this book opens up new avenues for interpreting Gaudí’s symbolism, discovering the ties existing between the work of the Catalan architect and that of the German painter Peter Lenz, which at the same time is rooted in the early Romantic period. Aimed at both specialists and the general public, Antoni Gaudí: Casa Bellesguard as the Key to His Symbolism not only broadens the knowledge and the documentation of Gaudí’s creative universe, but also contributes to enriching our perception of his work.
