Egyptian pregnancy test 3500 years ago:
https://www.cnn.com/2018/08/31/health/a ... knowledge/"A papyrus from ancient Egypt instructs a woman to pee into a bag of barley and a bag of emmer (the variety of wheat cultivated by ancient Egyptians), according to a researcher at the University of Copenhagen, who is studying the document.
"If they grow, she will give birth. If the barley grows, it is a boy. If the emmer grows, it is a girl. If they do not grow, she will not give birth," reads the text, written in a hieratic script -- the ancient Egyptians' cursive form of Hieroglyphic writing -- and dated to the New Kingdom era, sometime between 1500 and 1300 BC."
..." the pregnancy testing method had longevity. "We find the same test in Greek and Roman medicine, in the Middle East during the Middle Ages, and European medical traditions," says Schiødt. The test appears as late as the 1699, in a book of German folklore."
