The Octahedral Butterfly Map of the World, by Bernard
J.S. Cahill (1866-1944). first published in 1909, is a sadly neglected
monument of world map design. This resource presents some
of Cahill's articles, papers, and map variants, which he continued
to develop until 1940.
[Partial contents of Cahill Resource]:
Selected Cahill articles, uploaded by GK:
1909
B.J.S. Cahill, "An Account of
a New Land Map of the World" ( The Scottish Geographical
Magazine,
1909-09) p. 449-469. Reprinted by Gene Keyes as jpegs.
Cahill's original 1909 article,
which, after a strong critique of the prevailing Mercator, sets
forth the origin and logic of the Butterfly.
1912
B.J.S. Cahill, "A
Land Map of the World on a New Projection" (Journal
of the Association of Engineering Societies, 1913-10;
orig. 1912-10) p. 153-207, with 50 illustrations. Reformatted
in HTML by Gene Keyes.
Cahill's longest and most thoroughgoing published
exposition. Over three decades before Buckminster Fuller's 1943
Dymaxion map, Cahill had already created a far more elegant
octahedral world map, and shown how it is designed for thinking "planetarily".
1934
Cahill, B.J.S.,
"A World Map to End World Maps" ( Geografiska
Annaler, 1934) p. 97-108. Reformatted in HTML by Gene Keyes.
Argues against proliferation of arcane projections,
and sets forth three major Variants to improve upon his original
design: Conformal, Equal Area, and Gnomonic, within his basic
octahedral framework. "When finally map and globe practically agree
. . . the need of further world mapping comes naturally to an end."
1939
1) Cahill, B.J.S., "The Butterfly Map of the World Today" (Typescript, [1939] edited and formatted in HTML and with Foreword by Gene Keyes) 54 p.
Unpublished and unfinished
book typescript: history, vicissitudes, and prospects for Cahill's octahedral
map system.

Other papers and uploads
about the Cahill-Keyes map:
To facilitate comprehension of the entire
earth as a finite frame of natural and human events, a "Coherent
World Map System" is herewith propounded. All of its sub-squares
are based on the same Master World Profile (revised
Cahill projection) in a specified scale progression from tiny to
giant; at constant sizes, perspectives, and graticules; with geocells
of 1° or at least 5°; and formatted so that hierarchical miniatures
relate all main maps and globes in the system to one another: the whole
earth to the street where you live. All panels belong to a millimeter
matrix on a proposed 1/1,000,000 "Mega-map" version 40 meters long,
and its correlates: reduced, enlarged, or detached. Read entire précis.
