Belgian artist Joseph Lacasse ranks amongst of the most individual painters of the École de Paris. Born in 1894 into a working-class family in Tournai, Lacasse's artistic vocation was first outlined at the local stone quarries where he worked as a teenager. Lacasse was drawn to the austere mineral structure of the stone, the reflections of which he intuitively rendered in a fragmented way.

Over the years, Lacasse continued interest in the refraction of sunlight through the prisms embedded in the minerals of stones, combined with his mystical beliefs drawn from the ‘Beatitudes’ of Thomas Aquinas, led him to search for a supernatural union with the Universe through his art. Of his Abstract paintings, Lacasse said: "I do not know why I find the word ‘abstract’ inapt, for I regard the finished (abstract) painting as something that comes to live, a living object in itself and is therefore the opposite of abstract.”

Lacasse’s unique form of Abstraction was recognised and held in high esteem by his friends and contemporaries, such as Constantin Brancusi, Robert and Sonia Delaunay, and Michel Seuphor.

The works of Lacasse are included in the following museums: Musée d'art moderne de la Ville de Paris, Paris; Musée national d'art Moderne, Centre Pompidou, Paris; Musée des Beaux-Arts, Brussels; Musée de Tournai, Tournai; Tel Aviv Museum of Art, Tel Aviv; Eilat Museum, Eilat; Carnegie Institute, Pittsburgh; National Gallery of Victoria, Melbourne.
