One of the outstanding figures of the Enlightenment in France, Denis Diderot compiled the famous Encyclopedia. Malcolm Bradbury's book is also encyclopedic in approach, being a hotchpotch - very much in the spirit of Diderot, actually - of historical anecdotes, tableaux, and light-hearted observations of the world. The 'novel' - which it is not, really - seems unable to decide what it is doing, and the constant switch between the account of Diderot's visit to Russia in 1773, and the current odyssey of a bunch of, mainly Swedish, academics across the Baltic, is of doubtful significance. Some of Bradbury's travelogue humour is amusing, though, and the Swedish penchant for earnestness is keenly drawn.
