Nasceu em Vila do Conde. Poeta, com o pseudónimo de Saúl Dias, a sua linguagem plástica e escrita poética cruzam-se e complementam-se. Formou-se em Engenharia Civil na Faculdade do Porto em 1928 e frequentou a Escola de Belas Artes do Porto entre 1919 e 1921. Em 1936 expõs, pela primeira vez, individualmente na Sociedade Nacional de Belas Artes (SNBA). His writings, which had been collected and edited in the book “Poetic Wroks” received the Critics Prize in 1980. At the beginning his painting had a strong expressionist flavour, as from 1936, Júlio concentrated mostly on drawing and water-colours continuing to develop the lyrical component, and from the 70’s onwards his work showed cubist inspiration.
