Bolsena, a small town in Italy, on the E. shore of the Lake Bolsena, and 15 miles N.W. of Viterbo, is prettily situated on a height which is of great geological interest on account of the curious assemblage of basaltic materials that compose it. Here it was that in 1263 the miracle, painted by Raphael, of the Bleeding Host is said to have taken place. Bolsena is probably identical with Volsinium, an important Etruscan town where was a temple to the ancient cult of the goddess Nortia. Tiberius's minister, Sejanus, came from Bolsena.
