After the war, he settled in Brussels. There, he was co-founder of Jeune Peinture Belge and also had contacts with Cobra. In this period, his lasting friendship with Pierre Alechinsky and Hugo Claus also came about. In 1956, he went to the United States, where he was head of the painting department of the school of the Museum of Fine Arts in Boston. In 1974 he found a new home in the circle around gallery De Zwarte Panter in Antwerp. Jan Cox considered his artistry as an artistic and humanistic project. He painted surreal and magical scenes but also numerous haunting expressionist works. He chose classical themes: Orpheus, Homer’s Iliad, Judith and Holofernes, the Passion of Christ, in which autobiographical references merge with general human problems. They invite the viewer to reflect on the human condition, the hopes and terrors of the modern world.
The ethnographic literature of the 20th century focused mainly on the sculptural traditions of the numerous ethnic groups that populated Southern Nigeria while the more northern areas remained largely terra incognita. In 2013 Jan Strybol published a study on the sculpture of Northern Nigeria. He pointed out that in many parts of this region there are peoples who still had, at least until recently, their own sculptural tradition.
