In comparison with personal names toponyms have been rather neglected in studies on literary onomastics. Place names may seem less promising for onomastic research because authors tend to anchor their narratives in the actual world much more than characters. However, place names in literature fulfil important tasks: they mainly contribute to the fictional constitution of space. The question whether the actual counterparts of fictional place names are of any importance for the reader has been discussed very controversially. But place names may also help to create a certain mood or local colour. They even may indicate the passing of time. As all these phenomena are based on mental processes which take place in the reader’s brain this paper tries to study them with the help of actual cognitive science.
