Obscurantism was a terrible historical moment, just looking at the photos you share gives me terror :( in your photos the light is focused on a few small points of attention leaving most of the image dark, black. Like you, I am grateful for the arrival of the Age of Enlightenment and with it modernization and progress. It is regrettable that in my country we are living in a dark era in which everything is suspended, living and suffering the delay and deterioration of a society and this is even worse in education, in illustration. And I better stop because this is an issue that has no place here, dear friend, @velimir. A hug.
