Euphorion is the name given by Goethe to the marvellous child born of the mystic marriage of Faust and Helena. Who Faust is, and who Helena, we all know. Faust, of whom no man can remember the youth or childhood, seems to have come into the world by some evil spell, already old and with the faintness of body and of mind which are the heritage of age; and every additional year of mysterious study and abortive effort has made him more vacillating of step and uncertain of sight, but only more hungry of soul.
