In the thirteenth century Paris became celebrated for its illuminators, and the productions of Franco-Bolognese, whose skill in illuminating manuscripts was then paramount, is mentioned by Dante. Mr. Humphreys thus graphically describes the style of the fourteenth century:-- "It was a great artistic era--the architecture, the painting, the goldsmith's work, the elaborate productions in enamel, and the illuminator's art, were in beautiful harmony, being each founded upon similar principles of design and composition; even the art of writing lending itself to complete the chord of artistic harmony, by adopting that, crisp and angular feeling which the then general use of the pointed arch introduced into all works of artistic combination." * * * * * THE PHANTOM WORLD.[1] MR. CHRISTMAS, in his "Twin Giants," attacked the stronghold of popular superstition by exhibiting the foundations and growth of error in the early and ignorant ages, and of the progressive dissipation of these delusions as the light of history and science spread over the world. The present work is a translation from Calmet. It deals with spectres, vampyres, and all that tribe of visionary monsters. We have here the learning and opinion of the enlightened portion of the world a century ago. M. Calmet traversed all history for his facts, and gives us a mass of monkish inventions, which prove to what an extent the Romish church fostered superstition for its own purposes. We have dead men called from their graves to show the danger of neglecting to pay tithes, and to rivet on the rich the necessity of building churches, and paying liberally for masses. At p. 286 of vol. 1 we have a proof that the "knockings" which have made so much noise in the United States, are no novelty:-- "Humbert Birk, a burgess of note in the town of Oppenheim, had a country-house, called Berenbach. He died in the month of November, 1620, a few days before the feast of St. Martin. On the Saturday which followed his funeral they began to hear certain noises in the house where he had lived with his first wife; for at the time of his death he had married again. The master of this house, suspecting that it was his brother-in-law who haunted it, said to him: 'If you are Humbert, my brother-in-law, strike three times against the wall.' At the same time they heard three strokes only, for ordinarily he struck several times. Sometimes, also, he was heard at the fountain where they went for water, and he frightened all the neighborhood. He did not utter articulate sounds; but he would knock repeatedly, make a noise, or a groan or a shrill whistle, or sounds as of a person in lamentation."
