Denis Jully was born in Mulhouse (Strasbourg, France), the cradle of the Alsatian textile industry. He has sound training as a fabrics maker. After founding the government factories of the Shah of Iran, the former fabric ennobler has transferred to his paintings all the details of this craft, such as the color hues and degradation, the tension created by spaces on canvas, typical of printed fabrics.

Jully's works reveal a personal spirit characteristic of the Rhine school (neo-romantic and mystic). His canvases are permeated by the feeling of Nature, an allegorical nature where the mountain streams and vegetation are just archetypes. He defines his work as "allusive imagining," often finding inspiration in his many trips and the years he lived in Africa or Iran. Persian miniatures, rug samples, the ochre and red colors of the African soil, pieces of wood with history-all these elements are woven and combined in his paintings.
