Mediæval mythology, rich and gorgeous, is a compound like Corinthian brass, into which many pure ores have been fused, or it is a full turbid river drawn from numerous feeders, which had their sources in remote climes. It is a blending of primæval Keltic, Teutonic, Scandinavian, Italic, and Arab traditions, each adding a beauty, each yielding a charm, bat each accretion rendering the analysis more difficult. Pacciuchelli says:–“The Anio flows into the Tiber; pure as crystal it meets the tawny stream, and is lost in it, so that there is no more Anio, but the united stream is all Tiber.” So is it with each tributary to the tide of mediæval mythology. The moment it has blended its waters with the great and onward rolling flood, it is impossible to detect it with certainty; it has swollen the stream, but has lost its own identity. If we would analyse a particular myth, we must not go at once to the body of mediæval superstition, but strike at one of the tributaries before its absorption.
