The Book of Beasts: The Bestiary in the Medieval World Audio Tour takes visitors on an energetic and engaging journey with the beasts, both real and fantastical, that populated the Medieval world view. Bestiaries were akin to encyclopedias of animals and their attributes colorfully illustrated for readers to understand how they contributed to Christian ideals. Starting with the king of beasts, the lion, through the natural order, beasts were catalogued. Their purpose and powers were detailed. We developed a mobile audio tour, with narration by Game of Thrones actor Clive Russell, that playfully demonstrates each Medieval beast and their function, along with more “traditional” audio stops that link the much-repeated animal profiles with specific pages of various bestiaries.
