My sister is doing some work for a very poorly done online class. I’ve helped her out already but thought of this forum for putting the question out and seeing what we get. Unfortunately she has to find the information in “Western Civilization” by Jackson J. Spielvogel Volume One Eight Edition 2012.
What is the two greatest technological innovations (inventions, discoveries, improved techniques) introduced after 600 AD that influence 700 AD to 1500 AD?
I gave her the following: Crop Sharing, Field Rotation, and the horse drawn Plow. (she could only find reference to plow in general, I had her focus on new horse collar, horse shoes ect. because the horse was stronger and faster than it’s harder counterparts.)
I also put forth wind and water mills as apposed to human effort.
Thanks and advance,
