+‡Menadrie‡, is an Arte Mathematicall, which demonstrateth, how, aboue Natures vertue and power simple: Vertue and force may be multiplied: and so, to direct, to lift, to pull to, and to put or cast fro, any multiplied or simple, determined Vertue, Waight or Force: naturally, not, so, directible or moueable.+ Very much is this Art furdred by other Artes: as, in some pointes, by _Perspectiue_: in some, by _Statike_: in some, by _Trochilike_: and in other, by _Helicosophie_: and _Pneumatithmie_. By this Art, all Cranes, Gybbettes, & Ingines to lift vp, or to force any thing, any maner way, are ordred: and the certaine cause of their force, is knowne: As, the force which one man hath with the Duche waghen Racke: therwith, to set vp agayne, a mighty waghen laden, being ouerthrowne. The force of the Crossebow Racke, is certainly, here, demonstrated. The reason, why one mã, doth with a leauer, lift that, which Sixe men, with their handes onely, could not, so easily do. By this Arte, in our common Cranes in London, where powre is to Crane vp, the waight of 2000. pound: by two Wheles more (by good order added) Arte concludeth, that there may be Craned vp 200000. pound waight &c. So well knew _Archimedes_ this Arte: that he alone, with his deuises and engynes, (twise or thrise) spoyled and discomfited the whole Army and Hoste of the Romaines, besieging _Syracusa_, [=Plutarchus in Marco Marcello.=] _Marcus Marcellus the Consul_, being their Generall Capitaine. [=Synesius in Epistolis.=] Such huge Stones, so many, with such force, and so farre, did he with his engynes hayle among them, out of the Citie. [=Polybius.=] [=Plinius.=] [=Quintilianus.=] [=T. Liuius.=] And by Sea likewise: though their Ships might come to the walls of _Syracusa_, yet hee vtterly confounded the Romaine Nauye. What with his mighty Stones hurlyng: [=* Athenæus.=] what with Pikes of * 18 fote long, made like shaftes: which he forced almost a quarter of a myle. What, with his catchyng hold of their Shyps, and hoysing them vp aboue the water, and suddenly letting them fall into the Sea againe: [= * Galenus.=] [=Anthemius.=] what with his * Burning Glasses: by which he fired their other Shippes a far-of: what, with his other pollicies, deuises, and engines, he so manfully acquit him selfe: that all the Force, courage, and pollicie of the Romaines (for a great season) could nothing preuaile, for the winning of Syracusa. Wherupon, the Romanes named _Archimedes_, _Briareus_, and _Centimanus_. _Zonaras_ maketh mention of one _Proclus_, who so well had perceiued _Archimedes_ Arte of _Menadrie_, and had so well inuented of his owne, that with his Burning Glasses, [Burning Glasses.]
