“…It must be observed that our reconstruction [5], based on our translation of text by Philon, is really automatic; this because, differently by previous reconstructions [7,12,13], a simple rotation of the crank was sufficient to move the cylinder, the slide, the slide hooking mechanism and the trigger mechanism.…”

“…The invention of the repeating catapult is tributed to Dionysius of Alexandria, (III Century B.C.) and was described by Philon of Byzantium [2,6,7,27,[30][31][32]. It can be considered as a concentration of the most advanced mechanical kinematic and automatic systems of the time, many of which are still widely used.…”

В статье описывается механическое действие метательных машин, используемых в римских легионах. Статья начинается с обзора тех исследований, которые были про-ведены автором за последние 15 лет, иногда в сотрудничестве с некоторыми коллега-ми. В выводах содержатся (почти) окончательные результаты изучения античных ме-тательных машин как одного из направлений общего исторического исследования. Представлены машины: баллиста, стреломет, катапульты, повторяющиеся катапульты и карробаллиста. Были рассмотрены образцы артиллерии с прямой и высоко выгну-той траекторией полета снарядов. Эти машины относятся к периоду, начиная от II века до н.э., и заканчивая падением империи в V веке н.э., но, главным образом, принадлежат к имперской римской армии.Ключевые слова: дизайн (конструкция) античных машин, римская артиллерия, ма-шинная терминология.The mechanical behavior and the performances of the throwing machines used by the Roman Legions ares presented. The paper starts from a synopsis of the studies that were carried on by the author, sometimes in cooperation with some colleagues, in the last 15 years on ancient throwing machines and represent the (almost) final results of this branch of his researches. The presented machines are: the ballista, the catapult, the repeating catapult, the carroballista and the onager. So, both direct firing and high arching artillery was considered. These machines belong to a period of time ranging from the II Century B.C. to the fall of the Empire in V Century A.D., but mostly belong to the Imperial Roman Armies.

was born in Syracuse, in the Greek colony of Sicily. He studied mathematics at the Museum in Alexandria. Archimedes systematized the design of simple machines and the study of their functions. He was probably the inventor of the compound pulley and developed a rigorous theory of levers and the kinematics of the screw. He is the founder of statics and of hydrostatics, and his machine designs fascinated subsequent writers. Archimedes was both a great engineer and a great inventor, but his books concentrated on applied mathematics and mechanics and rigorous mathematical proofs. Archimedes was also known as an outstanding astronomer; his observations of solstices were used by other astronomers of the era. Biographical NotesArchimedes (ca. 287-212 BC) was born in Syracuse, in the Greek colony of Sicily. His father was the astronomer and mathematician Phidias, and he was
