It starts by explaining that modern fantasy can be traced back to ancient folk tales and epics, which continue to inspire creators and fans. The first things to see there relate to fairy tales, which I've loved since I was a child. It continues by showing fantastic art and literature over the centuries. The photo to the left shows an 1882 edition of Goblin Market by Christina Rossetti, illustrated by Dante Gabriel Rossetti.
The history of fantasy literature is a topic I already knew quite well as I studied it at university as part of my degree. One course I took as part of my BA was Fantastic Literature and another was Heroic Epics in the Oral Tradition, so you can see this exhibition is right up my street. However, I still learnt things I didn't already know and saw some books that are now on my wish list!
The exhibition isn't just about books and art. There are displays relating to roleplaying games, fantasy boardgames and computer games. These are also things I enjoy. The picture at the top shows a section about a computer game called Fallen London, which I really got into in its early days.
I'm going to try to get back to the exhibition again before it closes in February because I enjoyed it so much. I thoroughly recommend going if you get the chance.
The British Library is at 96 Euston Rd., London NW1 2DB. You can get exhibition tickets here: https://fantasy.seetickets.com/timeslots/filter/fantasy-realms-of-imagination
