Language: Brazilian Portuguese. Gaudí became an icon. Considered one of the greatest artists of all time, his work, which seems to come from another planet, is studied in the main universities of architecture and engineering in the world. But Gaudí hated writing and did not even leave us the complete plan of the Sagrada Família temple. His aesthetic-philosophical and mystical visions, in addition to his totally innovative construction principles, would be lost if the Catalan architect Cesar Martinell Brunet had not become his great friend and recorded his conversations with the brilliant architect, from 1915 to 1926. The young César Martinell Brunet, still a student, finds Gaudí completely reclusive, dedicating himself exclusively to the construction of his masterpiece, the Sagrada Família. Considered eccentric, alienated, and out of fashion (was not even mentioned at the Faculty of Architecture of Barcelona), politically persecuted for affirming Catalan culture and abandoned by friends, who fled from him to avoid requests for donations for the construction of the temple, Gaudí becomes a confidant of the young architect, capturing, in those profound and inspired conversations, his entire magical, mystical, and poetic universe. 'Conversations with Gaudí', which the publisher Perspectiva publishes in its Debates collection, recovers the oral Gaudí, with all his humor, insights, and visionary spirit, and reveals the secrets of his constructive principles, fundamental for the understanding of his architecture, in a journey in which the reader, in each chapter, feels as if he were in the room with the great Catalan architect. A fundamental book for understanding his work, which will delight architects, engineers, visual artists, art history scholars, mystics, and admirers of his work.
