The looking-glass is of course a modern invention, but Greek and Roman maidens learned the art of finishing their toilet in the reflective "glass" of the shining pool, and later by the aid of mirrors of highly polished metal made by the craftsmen of Rome; some of which have been preserved. The surface to which this reflective polish was given was of copper alloyed with antimony and lead. Such mirrors were sometimes hung to the girdle, a custom not unknown to Shakespeare, who frequently makes mention of it. Artificial Lighting. Artificial light has been a necessity to man ever since primeval days. The whole story of the discovery of fire-making and the light it gave is an enchanting romance. The contrivances for procuring and lighting a fire and for the betterment of artificial light have been many, and throughout the ages they have received perhaps greater attention by the inventor than any other requirement of the race. Of all the curios of the period under review none have been more prolific than those associated with artificial light. The lamps of ancient Rome, of beautiful bronze and brass, contrasted with the clay or terra-cotta lamps of cruder forms which have been found in such quantities. Their chased patterns were often modelled on the earlier Greek vases, so many of which are to be seen in the British Museum among the rarities of the metal collector. No collection of copper and brass would be complete without examples of the arts and crafts of Rome, so beautifully exemplified in the charming lamps to be carried in the hand, to stand on pedestals, and for suspension from the ceiling. There was something in their ornamentation which carried them beyond the works of the utilitarian maker. A celebrated historian, referring to the lights of ancient Rome, speaks of their matchless grace and simplicity, and says, "They afford traces of decoration showing an elevation in the ornamentation of common articles of every-day use." The Roman lamp of bronze was carried everywhere the conquering armies went, and in Roman settlements in France, Italy, and in Northern Africa, as well as in Britain, the native artificers in copper and bronze saw in them designs to be imitated; and after the Empire of Rome had fallen, the models which emanated from the Imperial city served as the designs for lamps in many countries centuries afterwards. The illustrations shown in Figs. 9 and 10 represent bronze lamps--the former, Fig. 9, is cast, and is an early example; Fig. 10, however, is of a later period, and it is made of brass inlaid with copper. The examples found in this and other countries may be divided into two groups, those distinctly Roman and of early date and those of the days when the Christian religion was recognized by the Emperors and the State. These latter are known by the decorations upon them. Statues and Monuments.
