Lastly, it is prudently added, that, as there were three of the Gorgons, who represent war, Perseus singled her out for this expedition that was mortal; which affords this precept, that such kind of wars should be chose as may be brought to a conclusion without pursuing vast and infinite hopes. Again, Perseus’s setting-out is extremely well adapted to his undertaking, and in a manner commands success; he received dispatch from Mercury, secrecy from Pluto, and foresight from Pallas. It also contains an excellent allegory, that the wings given him by Mercury were for his heels, not for his shoulders; because expedition is not so much required in the first preparations for war, as in the subsequent matters, that administer to the first; for there is no error more frequent in war, than, after brisk preparations, to halt for subsidiary forces and effective supplies. The allegory of Pluto’s helmet, rendering men invisible and secret, is sufficiently evident of itself; but the mystery of the shield and the mirror lies deeper; and denotes, that not only a prudent caution must be had to defend, like the shield, but also such an address and penetration as may discover the strength, the motions, the counsels, and designs of the enemy; like the mirror of Pallas. But though Perseus may now seem extremely well prepared, there still remains the most important thing of all; before he enters upon the war, he must of necessity consult the Greæ. These Greæ are treasons; half, but degenerate sisters of the Gorgons; who are representatives of wars; for wars are generous and noble; but treasons base and vile. The Greæ are elegantly described as hoary-headed, and like old women from their birth; on account of the perpetual cares, fears, and trepidations attending traitors. Their force, also, before it breaks out into open revolt, consists either in an eye or a tooth; for all faction, alienated from a state, is both watchful and biting; and this eye and tooth are, as it were, common to all the disaffected; because whatever they learn and know is transmitted from one to another, as by the hands of faction. And for the tooth, they all bite with the same: and clamor with one throat; so that each of them singly expresses the multitude. These Greæ, therefore, must be prevailed upon by Perseus to lend him their eye and their tooth; the eye to give him indications, and make discoveries; the tooth for sowing rumors, raising envy, and stirring up the minds of the people. And when all these things are thus disposed and prepared, then follows the action of the war.
