Born in Egypt, Lebanese artist Mouna Bassili Sehnaoui attended the American University of Beirut and the University of Arizona, where she studied Fine Arts.

In the seventies, Bassili Sehnaoui was in charge of the Graphic Art Department of the Lebanese National Council of Tourism. She also produced designs for stamps, packaging, posters, and book illustrations and created films for the Lebanese public television station. She later learned painting and typography, two disciplines she taught in Lebanese universities.

Since the early nineties, she has produced albums of lithographs based on Phoenician legends and studied porcelain painting, while still working as a designer and illustrator. Bassili Sehnaoui has been exhibiting art since the mid-sixties. Her seemingly naïve paintings most often reference her own surroundings, her country and its cultural heritage. The works suggest a very personal interpretation of space where shapes and line interpenetrate in colourful harmonies.

Bassili Sehnaoui has participated in group exhibitions in Lebanon, Europe, the United States, and the Middle East. She has also had solo shows in Lebanon since 1973, as well as in Dubai, Paris and Saudi Arabia. In 1990, she had a painting selected for the 41st international Painting Grand Prix of Deauville, France.
