Jaime Fernandes was born in 1899, in a small village, near one of the most unspoiled and rebellious rivers of Portugal, the River Ze^zere. He grew up in an idyllic rural landscape, a crossing site with a geography of fertile lands, where gold, wolfram, and tin were extracted from its entrails. A small rural landowner, he married and watched over his five children up to 38 years of age, when he entered Miguel Bombarda Lunatic Asylum in Lisbon, 300 km from his village. He is the most important Portuguese author of art invented in a psychiatric asylum context. About ninety drawings in ink, lead pencil, and ballpoint pen on paper, of varied sizes and quality, are known. His artistic activity, entirely lacking the supervision of any visual art atelier, was encouraged by his hospital psychiatrist, who collected most drawings by Jaime. The crudeness of these drawings impresses the unwitting observer: they are anthropomorphic and zoomorphic representations - cattle, goats, elephants, fish, and birds. The human figures burst through as bodies are placed on hold, arms in the air, eyes wide open that observe, others, sometimes, appear merged with animals. Jaime practiced drawing and wrote lengthy semantically indecipherable texts, in a singular calligraphy, where time is set in long numbers. He did this solely motivated by the pure pleasure gained from this slow exercise of revisiting his memories. In that pleasure, he would have acquired a taste for the imaginary, the world of dreams and fantasies of creation, of being cherished by all who participated in the portraits that he gave us to observe. Jaime died in Lisbon in 1969. Text in English and French. AUTHORS: Joa~o Pedro Fro?is was born in Lisbon in 1957.
