Born in Missoula, Montana, Peter Flaccus received his B.A. from Amherst College and an M.F.A. in painting from Indiana University. He also studied at the Skowhegan School of Painting and Sculpture, where he returned in 1979 as a member of the faculty. He began his career in the early 1970’s in New York City, where he remained for twenty years, exhibiting his paintings in several galleries, most importantly the Zabriskie Gallery and Monique Knowlton Gallery. 

Moving to Rome at the beginning of the 1990’s, Flaccus began to experiment with encaustic, an ancient medium involving colored wax; this led to numerous group and solo exhibitions in the United States, Italy, Switzerland and France. 

Recent solo exhibitions include those at Maja Arte Contemporanea, Rome (2019, 2022), Galerie L&C Tirelli, Vevey, Switzerland (2021), Nizza Paradise, Lugano (2017), Palazzo Cerio/Intragallery, Capri (2015), Intragallery, Napoli (2018, 2014/15), Otto Gallery, Bologna (2014), Galleria La Nube di Oort, Rome (2014), Galleria Monty&Company, Rome (2014), l’Agart, Amilly, Francia (2009), Ninni Esposito Arte Contemporanea, Bari (2009, 2004, 2002, 2000), la Casa delle Letterature, Rome (2009), Il Frantoio di Capalbio, Toscana (2007), Stiftung Müllerhaus, Lenzburg, Switzerland (2005), Galleria A.A.M., Rome (2004), Zabriskie Gallery, New York, (2004).
