Legendary rock act Led Zeppelin got their name from an equally legendary twelfth-century Cistercian monk, Comte Leo de Zepheline, a wealthy French duke who renounced his riches to lead a simple life worshipping God. He was famous for drinking, gambling and writing bawdy poetry (which ultimately led to his excommunication) and the words to 'Stairway to Heaven' are based directly on one of his verses.
