From 1951 to 1955 he worked with the Gruppo mosaicisti of Ravenna and restored many mosaics. Also in 1951, at the end of November, he arrived in Paris to teach at the Ecole d'Art Italien (School of Italian Art) as an assistant to the painter Gino Severini, founder and director of the school. Together with another mosaicist, his fellow Ravennan Lino Melano, he executed mosaic works for artists including Fernand Léger, Georges Braque, Marc Chagall, Jean Bazaine, and Raoul Ubac. He collaborated also on the mosaic for the façade of the Musée national Fernand Léger in Biot (Alpes-Maritimes).

From 1961 he had a studio in the artists' residence La Ruche at 2, passage de Dantzing in Paris, the place described by Lorenzo Viani in the book Parigi 1925 (Paris 1925), published by Fratelli Treves. In 1962, in another collaboration with Braque, he created the famous long fish tank of the Fondation Maeght in St Paul de Vence. His collaborations with many illustrious artists continued; the last was Jean-Michel Folon. Many of his personal works in painting and mosaics are in prominent private and public collections.

Question: What century was this architecture popular? Passage:St. Raphael's is a high Gothic Revival structure, built of sandstone from Berea. Since construction in the 1890s, it has been one of Springfield's most distinctive buildings, due in large part to its two front towers — the bell tower is high, and the principal tower . By climbing 156 steps to the summit of the principal tower, one gains a panoramic view of the city and surrounding countryside. The building's general plan is that of a streamlined Latin cross, with slight gabled projections near the rear forming the crosspieces. Three entrances pierce the facade, while lancet windows of similar height are placed at varying locations in the towers, and two-story windows fill the side bays. Widest and tallest are the windows placed in the rear-side projections and above the entrances on the facade. Both towers are topped with pointed roofs, surrounded by ornamental pointed roofs of far smaller sizes, while the roof of the main part of the church is a steep gable. Despite extensive Gothic Revival detailing, such as the pointed-arch windows and doorways, the building also retains some elements of the Romanesque Revival style, including the false buttresses and columns around the main entrance, as well as the sheer massing of both towers. By the time that the building was complete, parishioners had spent $75,000 on construction and ancillary costs. The architect for St. Raphael's was Charles A. Cregar, first among architects native to Springfield. Cregar was responsible for numerous grand buildings in Springfield, including City Hall, and St. Raphael's is among the chief examples of his work.
