The 18 th century German traveller, the emissary of Russia to the palace of the King of Kartl-Kakheti, Erekle II in 1777-1781, adventurist Jacob Rainegs (1744-1793), in addition to performance of his special task (study of mineral resources, mineral waters, metals, semi-precious stones, oil in Georgia) put a certain imprint on the cultural-educational and natural science-technical life of the country. He introduced many European technical novelties in the Georgian practice. Jacob Rainegs successfully accomplished his mission, convinced the King Erekle to sign the Treaty of Georgievsk and enhanced his contribution to this fact by his signature.
