The photographer Piero Pirari, son of the painter Giovanni Antonio Pirari Varriani, and his brother Antonio spent their childhood surrounded by art in their family home. Influenced by his father’s pictorial practice and fascinated by the possibility to use an innovative visual medium to represent reality, he chose to devote himself to photography, which was a true innovation in Sardinia at that time, despite the amateur work of some artists like Antonio Ballero and Sebastiano Satta - who were only two of the intellectuals that regularly went to Pirari’s family home. Piero Pirari, who was one of the closest friends of the professional photographer Sebastiano Guiso, took some of the most famous photographs of Barbagia between the 19th and the 20th century: a variegated collection, a repertoire of landscapes, domestic environments, people (including several "celebrities" of that time), in which the reporter ante litteram’s eye was always influenced by different pictorial contaminations. In the 1950s, he made the first 16mm color documentaries of Nuoro. The Nuoro’s Istituto Superiore Regionale Etnografico dedicated an important retrospective exhibition to Piero Pirari in 1977, when it obtained 1800 original prints and 201 negatives that are still included in the Fondo Pirari.
