Mariette Egreteau Martelli was born in France but now lives in Arezzo, where she has been a teacher for more than thirty years. She has a scientific background and has always been interested in the link between science and art, with her curiosity fully satisfied in the spectacle offered by nature.
Light games on ordinary objects, the deformation of reality in shades and reflexes, the transparency of the sky and water are her favourite subjects. She mostly uses watercolour to express herself, for its immediacy and union between water and light. Since 1998 she has taken part in a number of collective and personal exhibitions. She is bilingual in French and Italian and fluent in English.
