Jean Lambert-Rucki was born in Krakow in 1888 as Lambert Rucki; his father was a Pole and his mother a Hungarian. Having studied under Józef Mehoffer, he emigrated to France before the First World War, where he gained recognition as a sculptor, maker of applied art and painter. He developed his own artistic language, created as a result of being inspired by his contemporary art as well as Byzantine, medieval and traditional African art. From the 1930s onwards, he became increasingly involved in the creation of sacred art. In response to the need to rebuild churches from the devastation of war, Jean Lambert-Rucki produced, among other things, cement polychrome bas-reliefs on the façade of the church in Lèves, destroyed during the fighting in 1944 and rebuilt to the design of Jean Rédreau. On the left-hand side of the portal is the scene of the Last Supper (without Judas, but with a woman without a halo), on the right-hand side are three Passion scenes - the Crucifixion, the Deposition from the Cross and the Entombment, above on the right-hand side of the façade is the Ascension of Christ. The bas-reliefs are executed in the artist's characteristic simplified, archaizing style. Cement reliefs, polychrome; Christ figure approx. 4 m high, reliefs on the right side approx. 3 m high.
