The museum at Munich contains a very interesting piece of pottery, which is supposed to represent one of the lake villages or hamlets of the era when the people of Switzerland dwelt in houses erected on piles driven into the bottom of the lakes of that country. The accompanying illustration represents it. The double spiral ornament upon it shows that it belongs to the Bronze Age. Among the curious relics of the Bronze Age are a number of razor-like knives; from which we may conclude that the habit of shaving the whole or some part of the face or head dates back to a great antiquity. The illustrations below represent them. These knives were found in Denmark. The figures upon them represent ships, and it is not impossible that their curious appendages may have been a primitive kind of sails. BRONZE RAZOR-KNIVES. An examination of the second of these bronze knives reveals a singular feature: Upon the handle of the razor there are ten series of lines; the stars in the sky are ten in number; and there were probably ten rings at the left-hand side of the figure, two being obliterated. There were, we are told, ten sub-kingdoms in Atlantis; and precisely as the thirteen stripes on the American flag symbolize the thirteen original States of the Union, so the recurrence of the figure ten in the emblems upon this bronze implement may have reference to the ten subdivisions of Atlantis. The large object in the middle of this ship may be intended to represent a palm-tree--the symbol, as we shall see, in America, of Aztlan, or Atlantis. We have but to compare the pictures of the ships upon these ancient razor-knives with the accompanying representations of a Roman galley and a ship of William the Conqueror's time, to see that there can be no question that they represented the galleys of that remote age. They are doubtless faithful portraits of the great vessels which Plato described as filling the harbors of Atlantis. SHIP OF WILLIAM THE CONQUERER. We give on page 258 a representation of a bronze dagger found in Ireland, a strongly-made weapon. The cut below it represents the only implement of the Bronze Age yet found containing an inscription. It has been impossible to decipher it, or even to tell to what group of languages its alphabet belongs. It is proper to note, in connection with a discussion of the Bronze Age, that our word bronze is derived from the Basque, or Iberian broncea, from which the Spanish derive bronce, and the Italians bronzo. The copper mines of the Basques were extensively worked at a very early age of the world, either by the people of Atlantis or by the Basques themselves, a colony from Atlantis. The probabilities are that the name for bronze, as well as the metal itself, dates back to Plato's island.
