In fact, the themes and settings of the book make it somewhat of a mirror image to its predecessor, Alice's Adventures in Wonderland (1865). The first book begins in the warm outdoors, on 4 May; uses frequent changes in size as a plot device; and draws on the imagery of playing cards. The second book, however, opens indoors on a snowy, wintry night exactly six months later, on 4 November (the day before Guy Fawkes Night); uses frequent changes in time and spatial directions as a plot device; and draws on the imagery of chess. Chess While the first Alice novel took playing cards as a theme, Through the Looking-Glass instead used chess; most of the main characters are represented by chess pieces, with Alice being a pawn. The looking-glass world consists of square fields divided by brooks or streams, and the crossing of each brook typically signifies a change in scene, with Alice advancing one square. At the book's beginning, Carroll provided and explained a chess composition with descriptive notation, corresponding to the events of the story. Although the piece movements follow the rules of chess, other basic rules are ignored: one player (White) makes several consecutive moves while the (Red/Black) opponent's moves are skipped, and a late check (12... Qe8+) is left undealt with. Carroll also explained that certain items listed in the composition do not have corresponding piece moves but simply refer to the story, e.g. the "castling of the three Queens, which is merely a way of saying that they entered the palace". Despite these liberties, the final position is an authentic checkmate. The most extensive treatment of the chess motif in Carroll's novel was made by Glen Downey in his master's thesis, later expanded and incorporated into his dissertation on the use of chess as a device in Victorian fiction. In the former piece, Downey gave the composition's moves in algebraic notation: 1... Qh5 2. d4 3. Qc4 4. Qc5 5. d5 6. Qf8 7. d6 8. Qc8 9. d7 Ne7+
