To pass, however, from streets to street-illumination. Parisians of to-day, accustomed to the brilliancy of gas, which turns night almost into day, can scarcely believe that two centuries ago their town knew no other light than that of the moon and stars. It was the case, nevertheless; previously to 1667 not a public lamp existed. The necessity of street illumination had already, however, been recognised by a civic regulation which required householders, in those localities where garrotting had become too frequent, to place beneath their first-floor window, at 9 p.m., a lantern which might cast its beams into the street. It was M. de la Reynie, lieutenant of police for Paris, who first, in 1667, instituted public lamps. At the outset a lamp was placed at the end of each street, with a third in the middle. Then, after a time, the number of lamps was increased in streets of exceptional length. Each containing a candle, these “lanternes” were suspended by a rope from a crooked iron bar in the form of the gallows. The lamps introduced by La Reynie marked a certain progress in civilisation. They at least diminished in a remarkable manner the number of night attacks. La Reynie’s lanterns lasted until 1776, when they were replaced by so-called reverbères, or reflecting lamps. In a few months more than half the streets in Paris were illuminated by the new lamps, which, with some modifications, remained in use until the introduction of gas.
