Vanitas, featuring hums, glows, and memento mori.
Fluorescence’s name and mechanism were defined by Sir George Gabriel Stokes in the mid-19th century (yes, that’s our friend Stokes of fluid dynamics fame). But the phenomenon itself had been defined much earlier at least by Athanasius Kircher, and possibly thousands of years earlier in ancient China, as a property not only of phosphorus, but of plants and even of fireflies, where it was eventually termed luciferin, after everyone’s favorite fallen angel.
Today we confine the phenomenon largely to tubes on office ceilings, illuminating circles for hells not envisaged by Dante. But it also ranges free in the body paint, hair color, and even tattoos with which some of the residents adorn themselves in the after hours, if not the afterlife.
In terms of a personal glow, what other people see in any of us is entirely up to them, and is subject to change at any moment. Will you glow in the dark if no one is there to see it?
In answer to aisling-stargazer, who asked, “how was fluorescence discovered?” and “what is it about me that others are so keen with but I can’t seem to understand?”
