Ministers on Europeana: Arūnas Gelūnas

Article by Arūnas Gelūnas, Minister of Culture:
One of the greatest contributions of old Lithuania to European and World science and culture is the work of Kazimieras Semenavičius ‘Artis Magnae Artilleriae’. In his book printed in Amsterdam in 1650, the Lithuanian scientist was the first person in the world to have described and drawn a multi-stage rocket – a prototype of the rocket used in cosmonautics today.
Author: Kazimieras Semenavičius (Siemienowicz Kazimierz)
Title: Artis magnae artilleriae pars prima. Studio et opera Casimiri Siemienowicz equitis Lithuani
Date: 1650, Amsterdam
The first part of ‘Artis Magnae Artilleriae’ was made up of 5 chapters (a total of 305 pages of text and 206 illustrations and drawings). In the first chapter, Semenavičius describes cannon calibers, their designs and applications. In the second chapter he analyses the technologies of gunpowder as well as other materials used in artillery. In the third most interesting and valuable chapter ‘About rockets’ he presents his most important discoveries: the ratio of rocket height to the width of its jet nozzle, a multi-stage rocket, the stabilisation of rockets with the help of wings, a rocket battery (a multi-stage rocket of sequential circuit). The scientist, who called war the biggest scourge of mankind, presents more than 20 examples of rockets loaded with powder, and accurately describes their properties and production . In the fourth and fifth chapters, the scientist summarised the achievements of fireworks used in war and for entertainment. For the first time in history of the world, the work of Kazimieras Semenavičius presented artillery not only as the art of war, but also as a branch of science based on precise mathematical calculations as well as well-understood laws of physics. this work was an unrivaled classic of artillery science right up to the beginning of the nineteenth century.
Semenavičius wrote his book ‘Artis Magnae Artilleriae in Latin. In the same year that it was published it was translated into French, later on – into the German, English, Dutch and Polish languages. The author was awarded various medals by foreign countries.
The military engineering inventions of the scientist of oldLithuania, lying in the pages of the seventeenth century book, are the result of targeted cultural and scientific patronage. It could be said that the insight and erudition of King Vladislovas Vaza provided a promising European scientist with a strong take-off pitch. It is truly amazing when a weighed decision to allow and support, provides an opportunity for unique and innovative research, which, in turn, alters the development direction and speed of a specific scientific and/or cultural area and allows a fresh look to be taken, as well as the available options to be evaluated.
