Focus on Leda Atomica and discuss the Structure of the painting.
Leda Atomica is organized according to a rigid mathematical framework, following the "divine proportion". Leda and the swan are set in a pentagon inside which has been inserted a five-point star of which Dalí made several sketches. The five points of the star symbolize the seeds of perfection: love, order, light (truth) willpower and word (action).
The harmony of the framework was calculated by the artist following the recommendations of Romanian mathematician Matila Ghyka. Unlike his contemporaries who took the view that mathematics distracted from or interrupted artistic inspiration, Dalí considered that any work of art, to be such, had to be based on composition and calculation. Ghyka's influence is clear in the mathematical formula of the golden ratio in the lower right of the image
