This ebook describes innovations and designs of historical engineers which are the precursors of the current. The a long time in most cases variety from three hundred B.C. to 1600 A.D. with a few exceptions from ahead of and after this era. As for the very historical ones, the ebook describes innovations (documented by means of archaeological reveals regularly from Pompei, Ercolano and Stabia) that mostly are little or no recognized and infrequently now not recognized in any respect. a few innovations are within the army box. the reason for this is that (unfortunately) many innovations and technological suggestions were conceived ranging from army purposes. The publication is split into 5 components. the 1st 4 components pertain to certain fields and current innovations normally conceived as much as the past due Roman Empire. innovations which are consultant of the engineering genius of the ancients and which may be regarded as milestones, each one of their respective box. The 5th half refers to fields of engineering (such as textiles and automation) during which vital options have been conceived additionally in additional fresh centuries. for every of the innovations provided, even the traditional ones of many centuries previous, the authors offer 3 parts of study and reference: • Written files (the classics) • Iconic references (coins, bas-reliefs, etc.) • Archaeological findings.

D. 950–1003, who became Pope Silvestro II) and the author of “Liber abaci ”, Leonardo Pisano (ca. 1180–1250), better known as “Fibonacci” because he was the son of Bonacci. 2 The mesolabio This device is also known for its solution of the problem of doubling the cube or the problem of Delos. The word “mesolabio” comes from the ancient Greek μεσος = middle and λαμβανω = to take. In fact, the mesolabio makes it possible to compute two mean proportional segments between two given segments. Some ancient Greek mathematicians proposed a solution of this problem; in the following paragraphs those solutions that were used to build devices are presented.

15 Epicyclic gear trains. Finally, it is possible that the mechanism of Antikythera has been used also for sailing applications: knowledge of the moon’s position is useful to predict the (spring and neap) tides. This was important for ships that went in and out of the ports by oar propulsion if they were military and by a square sail if they were merchant vessels. In the Mediterranean Sea, tides are not very strong but the Roman ships sailed even to the British Isles, crossing the English Channel.

A few days before Easter 1990 a group of sponge-fishers from Rhodes coming back from the Tunisian coasts, stopped at the little isle of Antikythera that is in the channel between Kythera and Crete that links the Mediterranean sea with the Aegean. This channel has been sailed for thousands of years by vessels from all countries and is ill famed because of many shipwrecks. The spongefisher’s cutter dropped anchor near a little bay called Port Potamo (lat. 35°52 30 N, long. 23°10 35 E) where Elias Stadiatis, 42 m deep, found a large ship that lay wrecked on the sea bed.
