Balancement majeur is a splendid example of Lacasse’s series of so-called ‘Balancement’ paintings with which he so genius-like responded to the popularity which Serge Poliakoff gained during Lacasse’s six-year absence from Paris during the war years spent in England as a resistance fighter in the government of Charles de Gaulle.
Upon his return to Paris in 1946, Lacasse was disillusioned to find that the public seemed to have forgotten his abstract works from the 1930’s which had initially inspired Poliakoff. Sonia Delaunay was one of the few who was disdained by Lacasse’s treatment of art history and wrote several times about Poliakoff’s debt to Lacasse.
However, Lacasse's adherence to the 'Beatitudes' of Thomas Aquinas led him to return to the art market with this delightful series of the mystical balancing of forms, executed masterfully in lyrical impressionist brushwork.

The works of Lacasse are included in the following museums: Musée d'art moderne de la Ville de 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; Musée des Arts Décoratifs, Paris.
