A vibrant and meticulously arranged composition of colorful spots, characteristic of Damien Hirst's iconic spot paintings series. Created in 2007, *Ergocalciferol* features evenly spaced circles of pure, unmixed colors set against a clean white background, reflecting Hirst's fascination with scientific order and the aesthetics of pharmaceutical culture. The work's title, referencing Vitamin D2, underscores the artist's ongoing exploration of medicine, mortality, and the human desire to control nature through science.
