Non-Euclidean geometry; a critical and historical study of its development
Roberto Bonola's history of non-Euclidean geometry, translated by H. S. Carslaw and published in English by Open Court, LaSalle, Illinois, in 1912 for mathematicians and students. The 34 figures are fine line diagrams on cream paper: circles crossed by arcs, chords and tangent lines, with italic letter labels and occasional hatching, useful as spare geometric motifs and line textures.
