Abstract
This text presents, discusses and articulates the theme in relation to the set of articles published in this edition. The articles presented problematize the fundamental notions that delimit the field of Visual Arts, according to their own perspectives. It is understood that these notions have been constantly reexamined and the main reason for this is the experimental character of artistic making and the adoption of original procedures and ways of thinking, challenging the very definition of a work of art. A whole repertoire of notions, and the relationships between them, constitute the constellation that establishes art as a field of knowledge.
