"What I saw in Barcelona – Gaudí – was the work of such strength, such faith, of an extraordinary technical capacity, manifested during a whole life of genius; of a man who carved the stones before his eyes in well thought out pattern. Gaudí is the ‘builder’ of the turn of the century, a man adept with stone, iron and brick."
