Paul left a significant body of work, composed mainly of studies of roses, landscapes of Brittany, the Loire region and southwestern France, landscapes of Italy, as well as still lifes and a few portraits. His style is a classical one characterized by a meticulous technique, a study of transparencies and reflections, of materials and lights.
Paul was born in Nantes on 1 October 1905. In 1919, he was awarded first place at the École supérieure des beaux-arts de Nantes.
Between1921 and 1923 he received bronze medals for artistic drawing from his teachers, Émile Simon, Emmanuel Fougerat and Stanislas Gauthier.
In 1936 and again in 1938, Paul Seston exhibited his works in his home City at the Société des beaux-arts de Nantes, and then in 1939 at the Salon nantais. In 1947, he exhibited in Paris at the Salon des artistes français5.
A painter of flowers, he exhibited in 1967 at the Floralies d'Orléans, in 1969 at the Floralies de Paris and in 1971 at the Floralies de Nantes. In 1970 and again in 1973, the magazine L'Amateur d'art distinguished him and dedicated articles to him.
In 1972, Paul devoted himself fully to his work as a painter and opened his own personal painting gallery, in the rue des Hauts-Pavés in Nantes. In 1974, he exhibited in France and in Europe and successively received honorary diplomas in the finals of the Deauville prize, in Geneva and Cannes. The same year, he received the diploma of honour in the final of the international Grand Prix des Sept Collines in Rome, Italy, a country he really admired and where he made several trips to Florence, Rome and Venice, which inspired a series of Italian landscapes.
In 1981, he received the silver medal awarded by the Société Arts-Sciences-Lettres.
In 1982, he exhibited at the International Rose Festival in Nantes and received the prize of honour in the artistic section. An article is devoted to him in the magazine Présence des Arts.
Paul enjoyed his own rose garden which often provided the flowers he painted. He died on 23 June 1985 at his house-studio in Nantes, rue des Hauts-Pavés.
