Sophie La Rosière is a fictitious 19th-century French painter whose work and life unfolds over a series of site-specific immersive installations and gallery-shows. Her abandoned and recently reconstructed studio from 1918 allows us a glimpse into her creative yet reclusive life, and tells about her passionate relationship with Florence Hasard. Her series of paintings, obscured with blackened beeswax, activated international investigations beyond the subject matter into the museum's restoration practices and artistic authorship.
