Quotes

 * Then next, the way to fortify your men; In champion grounds what figure serves you best, For which the quinque-angle form is meet, Because the corners there may fall more flat Whereas the fort may fittest be assail’d, And sharpest where th’ assault is desperate: The ditches must be deep; the counterscarps Narrow and steep; the walls made high and broad; The bulwarks and the rampires large and strong, With cavalieros and thick counterforts, And room within to lodge six thousand men; It must have privy ditches, countermines, And secret issuings to defend the ditch; It must have high argins and cover’d ways To keep the bulwark-fronts from battery, And parapets to hide the musketeers, Casemates to place the great artillery, And store of ordnance, that from every flank May scour the outward curtains of the fort, Dismount the cannon of the adverse part, Murder the foe, and save the walls from breach.
 * Christopher Marlowe, Tamburlaine (1590), Part II, act 3, scene 2
