""X" is one of the most provocative representations in contemporary culture: a symbol of capital, power, excess and illicit desire. Based on the connection between language and "lack," Sign after the X investigates the letter "X" that is used in our culture as part of a complex sign system that encompasses the evolution of language back to its mythic origins.". "Including many of her drawings, Marina Roy uses narrative - and the book conventions of the dedication, preface, introduction, postscript, appendices and index - to form a compendium of X words that is part philological treatise on the foundations of image and text, part illustration, part math lesson, and part language primer."--BOOK JACKET.
