I hope you have enjoyed reading this blog as much as I’ve enjoyed penning it. With 2015 having come to a close, I am looking back on what this blog has accomplished: I’ve introduced the concept of a comparative, shown you some of what I believe are exemplary pieces, and drilled into a few of them to understand them better. I hope this endeavor had both entertained and educated. My goal, which I am renewing today, is to tell the captivating story of these beautiful Victorian pieces in a way that endears them to you as they are to me. My objectives for 2016 are to increase the frequency of my posts, to propose new ideas that further the understanding of comparatives, and to develop a virtual library of text and images. I want to leave you smarter for having read my blog and perhaps slightly intrigued. I’d like to revisit a few of my most favorite items from 2015–I hope you like them, too.
Mitchell’s 1860 The World in Hemispheres has an interesting mirror image of the Great Lakes and St Lawrence. Showing them in reverse order maintains their relative position to the mouth of the St Lawrence, shown flowing in the opposite direction, and allows the reader to find landmarks around the Great Lakes in their relative positions by flipping them
Gay-Lussac’s flight to 23,000 feet in a balloon was quite a feat, in 1804, no less. Humboldt’s ascent of Mt Chimborazo to over 19,000 feet was also a technical milestone, and the data he collected a boon to science. It’s no wonder that these achievement appeared on mountains comparatives, they signaled man’s conquest over nature. Thomson and Lizars show both of these on their 1817 A Comparative View.
As the discipline of comparatives expanded, cartographers developed innovative techniques to show the features. This yielded two results: comparatives did a better job of showing their features (more features, more information, more intuitive, etc), and it allows cartographers to differentiate their products in the market. Lucas’s Comparative Lengths of the Principal Rivers and A Map of the Principal Rivers by SDUK illustrate both the variety and innovation among comparatives. Where Lucas’s chart is very straightforward, showing river lengths by continent draining westwardly, the SDUK comparative shows both river direction and length emptying into a central water body.
The most data-rich of the comparatives I covered this year are Tallis’s Comparative View of the Principal Waterfalls, Islands, Lakes, Rivers and Mountains of the eastern and western hemispheres. They include each of the 5 classes of features shown in comparatives and also range from the early tableau style popular among the earliest comparatives (the waterfalls panels) and move to the more developed format of later comparatives (mountains & rivers).
Thank you for your readership in this blog’s first year; you have brought valuable insights through your comments and direct messages and I hope to continue the dialog in the new year. May 2016 bring you health and happiness.
