The work of the Dutch artist Gerard Caris is based on pentagonal structures. His work shows us the possibilities and stimuli that emerge from geometric structural thinking concentrated on regular pentagons. The artist developed aesthetical expressions by exploring pentagonal structures in the plane as well as in space. The paper tries to understand and reproduce the developments of his art creations in the form of drawings based on the pentagon as well as sculptures based on the dodecahedron. The artist’s way to explore pentagonal structures will be related to the geometric research and the aesthetic categories by evaluating Gerard Caris’ art in its relation to order and innovation.
