'I think an animal which is close to mythical is the Steller's Sea Eagle,' he says. Though these legendary beasts have their roots in literary allegories, Stephen says it is no surprise that some of the most spectacular animals inspire legendary counterparts. Yet somehow one feels rather sorry for him.' 'The other a plain straight forward growling, slobbering, slavering beast like a horribly mutated hybrid of pit bull, bulldog and Rottweiler perhaps. 'One is beautiful, serene, powerful, mysterious,' says Stephen. As a result, it's no surprise that the fantastic beasts which inspire him the most come from ancient Greek culture, describing it as a 'dead heat' between Pegasus and Cerberus. Stephen is no stranger to legends, having published a series of books on Greek mythology. We have sat in the caves, and now around our books and screens, glad to be safe, but needing to know about the dangers and the wonders out there in the wider world.' Why do we create fantastic beasts?

'This range of countervailing emotions are ones that mythology, story-telling, fairy-tales and more have always comforted and alarmed us with. 'I think the stories of mythical beasts are so compelling because of their mixture of fear, dread, excitement and comfort,' Stephen explains to the Museum.
