Joseph Mallord William Turner has been the subject of a number of projects recently, from the 2014 biopic Mr. Turner to the exhibition J. M. W. Turner: Painting Set Free (currently on view at the De Young Museum in San Francisco). For today's episode, we discuss Turner's depictions of the sea, a subject he represented throughout his career and which helps us understand the complexity of his art and ideas: the picturesque, sublime, engraving, etching, Immanuel Kant, Goethe’s color theory, Isaac Newton—we’ve got it all in here!
