How to conveniently transport heavy loads

by means of men and animals/

Many kinds of the most distinguished/ useful/ convenient

and curious machines, levers, pulleys, blocks and tackle, winches, earth- and wall-screws, as well as compound scaffolding tools, to be pulled and driven by one man as well as many men and animals, in order to bring, lift, guide, and set heavy loads, stones, columns, obelisks, earth, trees, and the like, from one place to another, from the depths to the heights, or from one height to another,

Roller works, wagons, lifting frames, windlasses, ground-winches,

cranes, ship bridges, lifting and sliding ladders, lifting rafts, inventions to transport and erect large stones and obelisks, as well as the curious and so-called Machina Coelestis Celestial Machine, Obeliscus Vaticanus Vatican Obelisk, and many others, presented both in copper engravings and in clear description, and provided and brought to light with the necessary Axiomatibus axioms, mechanical rules, and a treatise on friction and how to reduce it.

A work that is very useful and necessary

for all architects, engineers, builders, master builders,

stone masons, carpenters, bricklayers, and fountain masters.
