When I first heard of the cyanometer, I imagined a complicated machine with dials, cranks, and knobs. But what de Saussure actually &#8216;invented&#8217; was a cardboard chart with 53 cut-out squares sitting alongside 53 numbered swatches, or &#8216;nuances&#8217;, as he called them, of blue: you simply hold the sheet up to the sky and match its color, to the best of your ability, to a swatch. As in Humboldt&#8217;s Travels (Ross, 1852): &#8216;We beheld with admiration the azure colour of the sky. Its intensity at the zenith appeared to correspond to 41\u00b0 of the cyanometer.&#8217; This latter sentence brings me great pleasure, but really it takes us no further \u2013 either into knowledge, or into beauty. <small>\u2013 Bluets, Maggie Nelson<\/small><\/p>\n<p><!--- die laatste zin bevalt me, omdat [etc] ---><\/p>\n","protected":false},"excerpt":{"rendered":"<p>105.
