The mystery of the missing tapestry. In this episode, Professor Antony Moulis recalls how in the early 2000s he discovered the correspondence of an unknown tapestry commissioned by Jørn Utzon for the Opera House, designed by acclaimed modernist architect Le Corbusier. How did these two great architects come to collaborate and why was this medieval artform embraced by modernist architects and artists in the 20th century? How did the tapestry end up in Utzon’s home before resurfacing at an auction house, and why did it have mashed potato on it? Sydney Opera House CEO Louise Herron AM tells the story of how this incredible work of art finally found its way home.
