The plastic artist Riera i Aragó studied at the Superior School of Fine Arts in Barcelona. He has dedicated himself both to graphic work and to painting and sculpture. He recreates in his work a world of machines and gadgets that, humorously, recall those described in nineteenth-century science fiction stories, sometimes with a certain poignancy. This way, he criticises the irrational dazzlement of the power of the machine, as a symbol of progress, omnipresent in the twentieth century. He has organised countless solo and group exhibitions and is present in different collections of Museums.
