In the late 17th-century in Paris the first public lanterns made their appearance in the centre of the streets. They lit the road during the night. In 1763, the rverbres made their appearance. These were oil lamps with reflectors which were hung above the center of streets. The first public oil lamps in Milan, financed by revenues from a lottery, date from 1785. These were lanterns containing an oil lamp with a number of wicks. A semi-spherical reflector above the flame projected the light downwards, while another reflector, slightly concave and near the flame, served to direct the light laterally.
