AUTHOR: DODGSON, Charles Lutwidge (Lewis Carroll) TITLE: Curiosa Mathematica. Part I, A New Theory of Parallels. PUBLISHER: London: Horace Hart for Macmillan, 1888. DESCRIPTION: FIRST EDITION. 1 vol., diagrammatic frontispiece. Bound in the original black stamped tan cloth. CONDITION: Inner and outer hinges fine, head and foot of spine fine, some minor foxing to pastedowns and endpapers otherwise internally clean and bright, overall generally a VERY GOOD copy. REFERENCE: WMG&C #210. ADDITIONAL INFORMATION: The great majority of the seventy-two problems of "Curiosa Mathematica", chiefly in Algebra, Plane Geometry or Trigonometry, were 'almost all mentally worked out in the night, without a word or line put on paper till the daylight came. The Introduction describes the method of calculation, and states that Dodgson generally wrote the answer first, then the question and solution! He could distinctly visualize complicated diagrams in the dark, such as the frontispiece ... He published the problems to encourage the pastime as a means of avoiding undesired thought by concentration on a subject' (WMGC p. 181). ***FREE DOMESTIC SHIPPING***
