Should've mentioned the mandatory tonsure instead of the beard ban as the cause why there were so many barbers around monasteries. Of course it's a minor nitpick but an article that mentions the book Empire of the Scalpel should've pointed out the scalp shaving tradition of the catholic monasteries rather than some boring beard ban. Would've made a better story! I've also heard the church forbid monks from dealing with blood so they taught their barbers who were already familiar with sharp instruments to do the surgeries instead.
