As to my chosen signature...
My "classical" education was more Latin than Greek, so I have actually never ever read, let alone studied, Ovid. I followed scientific disciplines in my professional life, only recently taking an interest in classical themes.
What struck me about "Omnia Mutantur, Nihil Interit" was its timeless and literally universal applicability, a sentiment coined long before voluntary "recycling" or "make do and mend" initiatives were launched in the last century, and are becoming ever more important. Of course, a mistake made by every human generation since individual thought became possible, has been in believing that "we" have been the first to have what seems to be an original thought.
