In line with artistic questions raised by the minimalists, the work of Richard Serra deals with the object-hood and the self-referentiality of an artwork. His works are presences in space, devoid of all external references or meanings, and referring to nothing but themselves as objects. As one of the most prominent members of the post-minimalist generation, Serra also attaches great importance to the process of making these presences, and to the way this process and the logic of matter itself dictates the outcome of his artistic decisions. Serra explores the possibilities of materials and acts upon them within their natural confines. The results of his acts reveal the true nature of the materials that are processed.
