in building & mainteing the Fort, for the exteriour angles of the bulwarks placed vpon the angles of those figures, do fall out sharpe, and therefore are weake to resist a batterie, and hard to be defended, but in other figures they become flatter, and the more bulwarks a Fort hath, from the more places it may trauell and offende an enemy; but then it will require the greater garrison, prouision, and artillerie, the more cost in ma∣king, and care in kéeping. All which being considered, lyne out the Fort you pretend, if nothing do hinder the deliniation, nor that any part may be lesse approchable then other with equall sides and angles; but if any part may be better assured of the scituation then the rest, on that side lay out the longer sides and sharper angles, or both, to the intent the other part more easie to be approched, may be the more defenceable: yet héerein there must be a foresight, that the Fort may fall out as circu∣lar as possible it may, and being constrayned to fortifie néere any banke, or high ground, place a curten against it, and not a bulwarke, because a curten lying betwixt two flanks may be better defended then the front of a bulwarke from one, and that high ground more offended from the bulwarks on ei∣ther side of it: but if the banke be so large that it woulde reache from the front of one bulwarke vnto another, then in no case build neere none so noysome a neighbour, for vppon such a high grounde with little laboure may be cauelieros raysed in short tyme, which with artillerie may commaunde ouer the Fort, and impeache the defence of a breache, not∣withstanding any trauers that may be made, and finding any olde Fortresse subiecte to this mischiefe from whiche you woulde assure it, make on that parte the walles, dit∣ches, ramparts, bulwarks, cauelieros, and parapetes, déeper, higher, and larger, then of custome, laying the superficies of the rampart hanging somewhat inwarde. The Citie of Gaunt being subiect to such a high ground that lay hard vnto the ditch side thereof, by the aduise of the foresight, the Prince of Orange fell to worke, with spade, pickaxe, horsse, cart, & willing people, and in short time rebated the pride of it, carying away parte into a valley, and bringing parte into the Citie, making 0
