Retrospection 7

*In this retrospection, I discuss different aspects of colour, especially purple, and eyes, light, vision and blindness. We'll see how these subjects connect to health, science, history, symbols and philosophy.* People who visit my Index, are sometimes confused when they discover that some articles can be found listed in more than one place. I assure you that it is no mistake. It is because some articles belong to more than one topic. Let's say I would write about cats in Egypt; should it be labelled “Egyptology” or “Cats”? In such cases, I enter the article under both labels. There is also the case with extensive and very general topics, such as “Health” and “History”, that they contain so many quite diverse articles that (for the convenience of my readers) I have also listed some of them under more specific labels. For instance, an article about the history of coffee appears as well under general “History” as under more specific label “Coffee”; and article about eye health as well under “Health” as under “Eyes”. But note then that labels as “Coffee” or “Eyes” also contain articles discussing other aspects of coffee than history and other aspects of eyes than health. Sometimes I have completely removed a subtopic from the main topic. Japanology and Egyptology cover subjects that are indeed history, but I don't include them under the general label ”History” at all. New labels are created continuously as the Index grows, so everything is not entirely consistent. I apologise for that. The index is ever-changing and evolves as my published production at this platform grows, so it tends to become slightly erratic. Yet I hope it to some extent serves its purpose to help my readers to navigate in my production. Today we will look at some less extensive topics. First “Purple”, then “Eyes, Light, Vision, Blindness”. At first sight, this might seem a set of entirely different subjects, but they are related. https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#purple https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#eyes-light-vision-blindness From the beginning a neurologist & brain surgeon (I later slipped into other specialities as well), I have always been interested the senses of perception, and especially vision. Quite frankly, vision and eyes still hold mysteries we have not yet been able to penetrate completely. This subject also leads to the nature of light, and colour. My interest in colour grew far beyond the medical discipline, as I think can be seen from writings, even if I have not published much about colour here – not yet anyway. The subject of colour brings us to our first series today: “Purple”. It contains four articles: https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#purple Pontifex Maximus & The Imperial Purple of Rome, in which I discuss how the Roman legacy still lives in the purple and the office of the Roman Catholic Pope, a direct continuation of the old Roman office “Pontifex Maximus”. https://read.cash/@Mictorrani/pontifex-maximus-the-imperial-purple-of-rome-1bd0c336 Purple Earth; has the “green planet” been the “purple planet”? https://read.cash/@Mictorrani/purple-earth-5ec47aaf When Something is so Red, it is Purple: Purple in Chinese & Japanese Symbology. Here I combine my interest in colour with another interest of mine: symbols (which we will discuss in a future Retrospection). https://read.cash/@Mictorrani/when-something-is-so-red-it-is-purple-purple-in-chinese-japanese-symbology-70e051af Purple Light?

Some simple exercises would lessen the risk for eye damage – although no exercises will remove the harm caused by the blue light of the screens. https://read.cash/@Mictorrani/eye-health-eye-exercise-program-62736d7d The two last articles are related to seeing and art: Art as Visual Music & The Importance of Form https://read.cash/@Mictorrani/art-as-visual-music-the-importance-of-form-a040976f Practising Art: The Art of Seeing & Beyond Mere Seeing https://read.cash/@Mictorrani/practising-art-the-art-of-seeing-beyond-mere-seeing-a062694a Copyright © 2021 Meleonymica/Mictorrani.
