A Quadrivium is a medieval university curriculum involving the “mathematical arts” of arithmetic, geometry, astronomy, and music.
It also stands for, “the place where four roads meet.”
F-o(u)r us(e) at CLN, we want to draw your attention to the crossroads; imagine you have just taken the step that has brought you to a Quadrivium, if you feel more comfortable with one less choice it could be a trivium (a place where three roads meet); however, You Are Standing At A Crossroads. You can turn around and retread the path already taken, getting to know it even more intimately than you do now, or you can travel upon a path untaken and find yourself anew at the end of the journey…Robert Frost says in The Road Not Taken:
Two roads diverged in a yellow wood,And sorry I could not travel bothAnd be one traveler, long I stoodAnd looked down one as far as I couldTo where it bent in the undergrowth;Then took the other, as just as fair,And having perhaps the better claim,Because it was grassy and wanted wear;Though as for that the passing thereHad worn them really about the same,And both that morning equally layIn leaves no step had trodden black.Oh, I kept the first for another day!Yet knowing how way leads on to way,I doubted if I should ever come back.I shall be telling this with a sighSomewhere ages and ages hence:Two roads diverged in a wood, and I—I took the one less traveled by,And that has made all the difference.
