Religious fiction was an important and popular genre throughout the nineteenth and early twentieth century. Declining religiosity, the continued growth of non-denominational faiths and increasing urbanisation meant that religion and morality were the source of much discussion and debate. While many religious novels from this era have been forgotten today, they had a significant impact on the writings of those who came later. George Macdonald was one of the most influential of these authors. Important and well-known authors such as C S Lewis, G K Chesterton, Charles Kingsley, John Ruskin, Lewis Carroll, and E Nesbit all claim to have been inspired by him. His books 'Mary Marston' and 'Lilith' were very popular in the library.
