The Portland Vase, an ancient Roman glass cameo amphora held in the British Museum since the early 19th century, has been a global brand that has resonated with artists, makers, collectors, and consumers for centuries. The Portland Vase: Mania and Muse asks why and how a singular Classical vase becomes a legend, an “influencer,” and an artistic and commercial muse across time and place to artists such as Josiah Wedgwood, Viola Frey, Chris Wight, Michael Eden, Nicole Cherubini, Clare Twomey, and Roberto Lugo. Featuring more than 65 artworks, this exhibition examines the role of brands in our culture, considers why Classical traditions dominate the artistic canon, and how that tradition might be reconsidered and disrupted.
