It was Plato not Euclid who's said to have had that sign ("...no one ignorant of geometry..."). I agree that Euclid was a bad influence in this way, though we know so little about his time, maybe he'd have hated that part of his influence. We have a bit more variety from Archimedes: The Method, aka "here's how I really figured that stuff out". It was long lost until pretty recently, and so didn't get to influence anything post-Hellenistic. Also agreed about the notation. I hope something better evolves out of code.
