Archeologists made the groundbreaking discovery using DNA and chemical analyses to decode the dregs of ingredients left behind in Bes mugs, whose use had long remained a mystery. Now, scientists have proven the mugs were part of a ritual meant to provide the drinker with divine guidance and physical health.
