This latest volume of Harper Design's ongoing Duets series focuses on a special creative relationship indeed -- that between architect Josep Llu#65533;s Sert (1902-1983) and artist Joan Mir#65533; (1893-1983).Both Barcelona natives, the lifelong friends remained influential to one another as their individual careers evolved. Even when Sert emigrated to the United States (eventually becoming Professor and Dean at Harvard University), the two remained close: Sert designed Mir#65533;'s Mallorca studio; Mir#65533; paid him with a painting. Both men's styles reflect their Mediterranean roots. Joan Mir#65533;'s paintings evolved from the rich, poetic realism of his early works to later symbolic, abstract, organic forms, yet all retained the bold, decorative colors of the Catalan landscape. Josep Llu#65533;s Sert's growing concern with urban planning and balancing technology with humanity all remained informed by his Mediterranean origins. Studied together, these careers provide new insights and understanding in the appreciation of modern art and architecture.
