An Ancient Lake
Lake Nero, which Rostov hugs in an almost perfect semicircle, is the largest and one of the oldest lakes in the Yaroslavl region. It isn't deep: 4 meters (13 feet) at most and 1.5 meters (5 feet) on average. It was named by the Merya, an ancient Finno-Ugric tribe who once lived here and were allies of the Slavs. In their language the root ner- means “fresh water.” Short and to the point, and certainly better than the name Peter I gave it in his day, when he wanted to build his first “toy” fleet here: “a dirty puddle.”
