Paperback. Zustand: new. Paperback. . A machine is a combination of timbers fastened together, chiefly effica-cious in moving great weights. Such a machine is set in motion on sci-entific principles in circular rounds, which the Greeks call [Greek: kyklikekineois]. There is, however, a class intended for climbing, termed in Greek[Greek: akrobatikon], another worked by air, which with them is called[Greek: pneumatikon], and a third for hoisting; this the Greeks named[Greek: baroulkos]. In the climbing class are machines so disposed that onecan safely climb up high, by means of timbers set up on end and connectedby crossbeams, in order to view operations. In the pneumatic class, air isforced by pressure to produce sounds and tones as in an [Greek: organon].2. In the hoisting class, heavy weights are removed by machines which raisethem up and set them in position. The climbing machine displays no scien-tific principle, but merely a spirit of daring. It is held together by dowels andcrossbeams and twisted lashings and supporting props. A machine that getsits motive power by pneumatic pressure will produce pretty effects by scien-tific refinements. But the hoisting machine has opportunities for usefulness3 VITRUVIUS POLLIOwhich are greater and full of grandeur, and it is of the highest efficacy whenused with intelligence.3. Some of these act on the principle of the [Greek: mechane], others on thatof the [Greek: organon]. The difference between "machines" and "engines"is obviously this, that machines need more workmen and greater power tomake them take effect, as for instance ballistae and the beams of presses. En-gines, on the other hand, accomplish their purpose at the intelligent touch ofa single workman, as the scorpio or anisocycli when they are turned. There-fore engines, as well as machines, are, in principle, practical necessities, with-out which nothing can be unattended with difficulties.4. All machinery is derived from nature, and is founded on the teachingand instruction of the revolution of the firmament. Let us but consider theconnected revolutions of the sun, the moon, and the five planets, withoutthe revolution of which, due to mechanism, we should not have had thealternation of day and night, nor the ripening of fruits. Thus, when our an-cestors had seen that this was so, they took their models from nature, andby imitating them were led on by divine facts, until they perfected the con-trivances which are so serviceable in our life. Some things, with a view togreater convenience, they worked out by means of machines and their revo-lutions, others by means of engines, and so, whatever they found to be usefulfor investigations, for the arts, and for established practices, they took careto improve step by step on scientific principles.5. Let us take first a necessary invention, such as clothing, and see how thecombination of warp and woof on the loom, which does its work on theprinciple of an engine, not only protects the body by covering it, but alsogives it honourable apparel.
