Are You Medieval?
Medieval refers to the Middle Ages—the time  period from around A.D. 500 to 1450. When  people call something medieval, they often  mean “very old fashioned.” But some medieval  inventions are still used today. You might be  wearing one of them on your face! What has been is what will be, and what has been done is what will be done, and there is nothing new under the Sun. — Ecclesiastes 1:9
By my troth! According to World Atlas, you’re positively medieval if . . .
. . . you wear glasses.  Eyeglasses  were invented  in medieval  times around  the year 1268.

. . . you go to the library. 
. . . you go to the library.  Once, only rich people used libraries, and these were collections of books in their own houses. The first public library was created in the Middle Ages in Italy: the Malatesta Novello Library. Now that’s a good invention!
Medieval library books were so valuable they were kept chained up! Hey, at least you won’t get a late fine.
. . . you  have a dollar in your pocket.  Why carry around heavy silver and gold  when you could use paper bills instead?  Paper money was invented in China in 1023.
. . . you get your power from a windmill.  People still use wind  turbines to harness the  power of wind. They turn it  into electricity. Of course,  indoor electric power  wasn’t invented yet in  the Middle Ages, when  windmills ground up  grain or moved water.
But the mechanical clock we know and  love was invented in medieval times.
. . . you check the clock.  People have used  many methods of telling  time over the centuries.
(You can make some of the oldest timekeepers yourself: the water clock and the sundial.)
