Danube–Black Sea Canal
As Romania's justice system came under control of the Romanian Workers' Party and its Justice Minister Lucrețiu Pătrășcanu, Brezianu was obliged to leave his work and become an accountant in a wire factory. Soon, he found himself performing forced labor on the Danube–Black Sea Canal, which closed in 1955. Following his release, he was unable to return to legal work, and so he turned to art history and criticism. He wrote studies about Nicolae Tonitza and Nicolae Grigorescu, but his focus, through articles and books published starting in 1964, dealt with Constantin Brâncuși. His most important book, which came out in 1974, analyzed Brâncuși's Romanian sculptures.
