Brasseur, L. “Florence Nightingale’s Visual Rhetoric in the Rose Diagrams”
In this well-written piece, Lee Brasseur talks about “Florence Nightingale’s use of visual and verbal rhetoric in the design and presentation of her rose diagrams”. He discusses how she documented the failure of the Government and the Military in providing wounded and diseased soldiers with sanitary conditions to be housed in.
He gives a little bit of background on Ms. Nightingale, talking about how she was a born statistician, breaking societal norms, and also using statistics to dispute the claims by army doctors. I was surprised by all the background knowledge on her because I always thought that she was a nurse par excellence, but all this excited me.
Her use of the visual comparison of mortality rates in Manchester (then known for its poor mortality) versus those at the Crimean warfront was an interesting rhetorical decision, because it compares the warfront against a seemingly normal city, just to show the apathy towards the soldiers fighting the war. Brasseur considers the design of the rose diagram as unique, simply because something like that had never been done before, though Ms. Nightingale was inspired by others before her time.
The first rose diagram shows time-based as well as casualty-based progression. This, in itself, doesn’t impact the audience much, but it is telling how the casualties increased due to disease rather than the war itself. The second rose diagram shows the various causes of death, and this is a powerful representation, and this actually shows the apathetic behavior of the authorities. The third rose diagram compares mortality rates at two hospitals on the warfront versus that of a hospital in London, over a progression. This diagram is actually a solution to the problems since it shows how the casualties decreased once Ms. Nightingale’s recommended actions were taken.
Each of these rose diagrams follows a progression and complements each other. It is a form of powerful visual persuasion. All of these diagrams and the text use pathos, logic, explanations to convince the target audience. Her visual rhetorical tactics are used till today and her success was that their appeal incited action.
Florence Nightingale was one of the first successful information designers and prominent statisticians. Her approach to visual rhetoric is a triumph that has inspired many. This interesting article has made me look at visual rhetoric in a wholly positive way, and not something that adds variety to document design.
It shows me how visuals are as important as written content.
Could Florence Nightingale’s rose diagrams have been simplified even further or do you think they are easy enough to understand?
