Its meaning would elude scholars for 50 years. Susan Lupack explores the mysterious inscriptions. [Directed by Movult, narrated by Bethany Cutmore-Scott, music by Stephen LaRosa].

(This virtual conversation, hosted by TED's head of curation Helen Walters and arts and design curator Chee Pearlman, was recorded June 10, 2020.)
