This ebook describes the innovations and designs of historical engineers who're the precursors of the current. The interval levels frequently from three hundred B.C. to 1600 A.D. with a number of exceptions. some of the oldest innovations are documented by means of archaeological unearths, frequently little or no recognized, commonly from Pompeii, Herculaneum and Stabiae and show a shocking modernity of their conception.

Most of the innovations awarded within the first 4 elements of this ebook have been conceived as much as the past due Roman Empire and will be regarded as milestones, each one of their respective box. The 5th half concentrates on more moderen centuries. The 6th half offers with a few development building techniques.

Generally, for every of the awarded innovations, 3 components of study and reference are supplied: written files (the classics), iconic references (coins, bas-reliefs, etc.) and archaeological findings.

The authors didn't write this booklet for engineers purely; consequently they describe all of the units with out assuming vast technical wisdom. The authors’ major objective is to aim to speak their enthusiasm for the innovations and the inventors of the prior and to give a contribution to the interesting learn of the background of Engineering.

This moment variation contains new themes and chapters which are of exact curiosity to engineers.

4 is reported an ancient steelyard found at Hercolaneum. ) who was Archbishop of Seville and one of the most educated man of that age; he wrote about liberal arts, law, medicine, natural science, theology. In his treatise “De ponderibus et mensuris” (On the weights and measures), he calls statera the scale balance while the steelyard is called “Campana” after the name of the Italian region Campania where, according to him, the first example of this device was found. Really the word “campana” does not appear in the classic Latin literature but only in the later one.

In Babylon were built water clocks as old as the Egyptian ones but, although their existence is documented on clay tablets, none of them survived. C. An interesting example of an Indian water clock is at Nalanda, its working principle consists in a bowl having a little hole at its bottom that floats in a larger one containing water; the bowl sinks periodically and a mechanism linked to it beats a drum to mark the time. The working principle of this device is somehow similar to the one of the automaton “the elephant clock” by Al Jazari described in Chap.
