How bugs turned the world red

from Stories in Colour

We're on the search for the 'perfect red' with a pigment and dye that was so prized that it inspired international espionage and piracy, carried the death penalty if exported without a license, and built empires. But today you might find it in your strawberry yoghurt. This is the story of how bugs turned the world red with historian and writer Amy Butler Greenfield and National Gallery host Beks Leary. Amy is the granddaughter and great-granddaughter of dyers, and her award-winning history of cochineal, 'A Perfect Red', has been published in eight languages. A popular speaker on radio and television programs, Amy was born in Philadelphia, studied history at Oxford, and now lives with her family in Oxfordshire. ----- Watch the full episode on YouTube: https://youtu.be/Z2jEf3QH_ho You can email us with any questions via [email protected] Find out more about the podcast on our website: www.nationalgallery.org.uk/podcast ----- Paintings mentioned: Workshop of Albrecht Dürer with Hans Baldung Grien, ‘The Virgin and Child ('The Madonna with the Iris')’, about 1500-10.
