This book presents a series of recent ceramic works by Carlos Enrique Prado. These sculptures have been made using 3D modeling software and the 3D clay printer, a technology that is still considered new in ceramics. In general, they can be described as stacks or piles made from repeated copies of famous figurative sculptures, which have been assembled into new designs and compositions. The title, “Tautologies”, refers to the connection between the meaning of the term and the way in which the content of the pieces unfolds. Carlos Enrique Prado is a visual artist, who works predominantly in clay. He is a professor of sculpture and ceramics, currently teaching ceramics at the University of Miami, FL
