He was born in Rome and died in Perugia. His father was a civil servant, but his mother had interests in history and art. Dorazio attended the Julius Caesar lyceum in Rome as a young man. In 1943, the family fled to the Abruzzo, the family's home region. Dorazio worked briefly as a translator for the British army. After the war, he then took some courses in architecture in Rome.
But soon, he gravitated to painting, influenced by futurists such as Gino Severini, Antonio Corpora, Enrico Prampolini, and Giacomo Balla, but averse to the fascist background of many futurists, aligning himself with more left-leaning artists like Renato Guttuso. Along with Pietro Consagra, Achille Perille, and Giulio Turcato, in 1947 he belonged and helped formulate a manifesto by a group of abstract artists called Forma I. While imbued with the socialist leanings, this group, influenced by the abstractions of the Futurism movement, he did not follow the realist social commentary furthered by Guttuso. In 1947, he won a stipend from the French government to study at the École des Beaux-Arts of Paris.
Described as an outspoken, independent character who was the opposite of politically correct, Dorazio's use of materials and colors did not shift much over time. He is known for many paintings rich in color, highlighting thick bands of bright color, often cross-hatched grids While abstract, they do not neglect detail or complexity. The style is allied to what was later described as "Post-painterly abstraction" by Clement Greenberg. Wikipedia
