In this article, a remix produced by the artist Pogo and a mashup made by the artist Kutiman are examined as positioned within an aesthetic public sphere. Using the taxonomy afforded by the quadpartitia ratio, these mashups and remixes are pulled apart to reveal insights into how traces of authorship can be detected by juxtaposing original and mashed-up or remixed images. Ultimately, this article will show that locating traces of authorship in mashups and remixes not only adds depth to aesthetic appreciation but also illustrates the aesthetic dependence of mashups and remixes upon the media images that circulate within a given aesthetic public sphere.
