At that time, to illuminate a large area near the palace, during some kind of celebration, barrels were placed and set on fire.
Barrels were filled with brushwood or straw, resin was also added. Lanterns, bowls and scales were used for illumination. Basically, wax or paraffin candles were used for lighting in those days. Large numbers of large windows were made in houses for better illumination.
Later, gas lamps appeared, and later electric light sources began to be widely used. Currently, in addition to incandescent lamps, electric-saving and LED lamps are used.

It is a Grad-type launcher and a remote control with which the launch can be controlled remotely. The system is equipped with special 122 mm lighting projectiles. Just one fired projectile illuminates an area with a radius of about 500 meters for 90 seconds. The installation can be controlled by a calculation of two fighters.

After the main text was applied to the sheet, it was decorated with ornaments and miniature drawings. Quite often the very first letter on the page was illuminated. Such manuscripts are often called"Facial".
A colorful and bright ornament and drawing was applied along the edges of the sheet, coinciding in meaning with the text. To create illuminated books, natural pigments were used, including gold and silver powder, which made the drawing especially beautiful and shiny. This technique is one of the most difficult due to the fact that it is used on a small area, and often on a miniature scale.
