Answer
Bacon's breakthrough work, "Three Studies for Figures at the Base of a Crucifixion," is a triptych depicting three distorted and grotesque human figures. The painting, created in 1944, is considered a seminal work in Bacon's career, as it marked a departure from his earlier, more naturalistic style and established his signature approach to figuration, characterized by its emotional intensity, psychological depth, and exploration of existential themes.
