"'Eyes That Do Not See' is the provocative title of a chapter in Le Corbusier's Vers une Architecture ( 1923); nevertheless, for architects, eyes are the most generative apparatus capable to empower them to define the contours of their own professional realm. The facsimile editions of two recently published travelogues demonstrate that 'eyes that saw' and explore were systemic tools that transformed future architecture narrative in the case of Henry Hornbostel's travel journal of his grand tour of Europe, dated 1893, and of Le Corbusier's Album Punjab 1951 . Created half a century apart, inspired in the former's elaboration by the optimism of the late Enlightenment culture, and in the latter's imagination by the powerful dimension of the creation of a new capital, these sketchbooks spoke to several aspects of the career of these designers. They also suggest that travel narratives are unique in the education of the architects and serve to create strong pedagogical vehicles. In this superbly published facsimile edition, Francesca Torello charts the intellectual odyssey of the young Hornbostel and traces the trajectory for his rich, intense, and fortunate career.".
