I was cleaning out my Evernote inbox and saw two topics side by side: "The Lost Art of Memorizing Poetry" and the "The Lost Art of Illustrating Your Favorite Books." How many Lost Arts could there be? Are they really lost, were they superseded, or are they underground? Have the practitioners and teachers died out? Did that many people really practice it? And when we say "art" we really mean "skill," right? Or do we mean a craft that elevated both the user and the practice? There's a rather weary head-shake and heavy sigh of regret that seems to go with the phrase "lost art."
As always, when faced with an odd little eyeworm like that, I feed it into Google to see what other pages out there are using, re-using, and wearing out those specific words in that specific order. I tweaked this search a bit and decided dropping the quotation marks netted a few good articles I missed otherwise; I also removed lyrics from the search. Try it yourself.
What do we learn from this? I have no idea. I just find it interesting to see what others consider a necessary skill or behavior that no one in their self-identified peer group seems to find relevant anymore.
