(Keep in mind that these are only the oldest surviving examples of these objects – many of these may have existed or are known to have existed even earlier.) 1) Oldest Socks (1,500 years old) These Egyptian wool socks, designed to go with sandals, were knitted between 300 and 499 AD and found in the 19th century. 2) Oldest Written Recipe (5,000 years old) “A Sumerian Beer recipe dating back to 3000 BC. The result beer is very strong and would contain chunks of bread floating around in it.” 3) Oldest Sunglasses (800 years old) The world’s oldest sunglasses were discovered on Baffin Island in Canada. They were snow goggles, designed to reduce the sun’s glare reflecting from the snow. 4) Oldest Sculpture Of A Human Form (35,000 – 40,000 years old) At 35,000-40,000 years old, Venus of Hohle is the oldest statue depicting a human figure. This mammoth-ivory figurine was found in Germany. 5) Oldest Shoe (5,500 years old) This 5,500-year-old cowhide moccasin was found in a cave in Armenia, preserved by grass and dry sheep dung. The left shoe was not found. 6) Oldest Instrument (40,000 years old) This 40,000-year-old vulture-bone flute was found in southern Germany. Some scientists believe that music may have given our ancestors a strategic advantage over Neanderthals. 7) Oldest Pants (3,300 years old) The oldest pair of pants in the world is 3,300 years old, and it was found in Western China. 8) Oldest “Flush” Toilets (2,000 years old) Ephesus, an ancient city in Turkey, had “flushing” toilets. Running water below the seats carried waste away into a nearby river. 9) Oldest Brassiere (500 years old) This bra was used between 1390 and 1485 in Austria. Earlier historical descriptions for “breast bags” do exist, but they had never been seen. 10) Oldest Prosthetic (3,000 years old) This 3,000-year-old prosthetic was used to help someone in Egypt walk again. Tests carried out with a replica proved that it was a working, practical prosthetic, not just a cosmetic one.
