London, J. Robinson, 1752. Hardback. Likely a pirated edition. A very good copy in half vellum. An important early example of what would become science fiction. Three editions were published in 1752 at about the same time, the actual first edition doesn't have the date on the title page, unlike the present copy. The other two copies are thought to be unauthorised, and likely published in Paris or Germany. An adventure following the journey of alien visitors to Earth from Sirius and Saturn. "...inaugurated a tradition of superior aliens who come to lecture humans about the need to improve themselves" [Westfahl, volI, p17]. Some scuffing to the binding, handwritten title on the spine, ink name to endpaper, top edge dusty. A presentable copy of an important milestone in the history of science fiction.
