Amélie Bouvier: "The most beautiful representations of the sun I ever saw were in Etienne Trouvelot’s notebooks at The Harvard-Smithsonian Center for Astrophysics Library. These 19th century lithographs were mostly fantastic solar explosions illustrated by expanses of plasma, strangely reminiscent of plant details or the physiognomy of clouds, except that their predominant red colour plunges us straight into the heat and danger of the subject. The term 'Solar Demons' is used in a database of the Belgian observatory which aims to develop a detection system for flares, luminosity drops and EUV waves coming from the Sun. It evokes the duality of our relationship with the Sun. The drawings gathered under this dramatic and allegorical title are directly inspired by shapes illustrated in historical observations of solar flares."
