I would argue that Latin is the first victim of modernism, its decline analogous to the worst fears surrounding such educational reform as Common Core. The early modern period saw a break in tradition; the pedagogy of antiquity, the Middle Ages, and the Renaissance gave way to modern techniques and innovations, and for the past two centuries we have let our students wallow in the mire they created.
I have been brushing up on my Latin and German by means of Duolingo. It has certainly helped, since I can now understand both languages when I hear them. But i also just ordered a Latin-English Vulgate to further my study.
