Academic art
Delville's artistic style is strongly influenced by the Classical tradition. He was a lifelong advocate of the value of the Classical training taught in the Academies. He believed that the discipline acquired as a result of this training was not an end in itself, but rather a valuable means of acquiring a solid drawing and painting technique to allow artists freely to develop their personal artistic style, without inhibiting their individual creative personality. Delville was a respected Academic art teacher. He was employed at the Glasgow School of Art from 1900 to 1906 and as Professor of drawing at the "Académie des Beaux-arts" in Brussels thereafter until 1937.
