〈 math 〉〈 math 〉

I Do not doubpte but many who have not longe pra∣ctised 〈 math 〉〈 math 〉 in the framinge of squadrones, and that are not skilfull in the severall divisiones of the same, and in particular suche as are not able in Arithmetike, will in the begining finde greate difficulte in well orderinge and dividinge in proportion thiese batteles withe centeres, and lined every way pro∣porsionally withe sundrie sortes of weapones. Wherfore i tought fit to set downe in writinge the maner of theyre severall divisiones. To wourke the whiche yove muste bigin withe the center; Then withe the divisiones of youre unarmed and armed pikes, and then withe the divisiones of youre shott to see how they fall to line the squadron of pikes in proportion as hire folowethe.

To wourke the whiche, firste bigin with 49. youre propounded number for the voide center, and demaunde for the square roote of 49. whiche is 7. so youe finde that 7. is the front and flanke of the void center, that don say that youre voide place or center ocupies 21. foote in front and 49. in flanke, then place downe 49. the center and 121. the unarmed pikes whiche two adisiones, will amont to 170. oute of whiche take the square roote which is 13. and say that 13. is the front of the vnarmed pikes withe the voide center, that 〈 math 〉〈 math 〉 don substract 7. the front of the center oute of 13. the front of the center and unarmed, and youe shall finde that 6. remaniethe, this 6 divide by 2! and the quotient will be 3. so say that by youre division youe finde that 3. unarmed pi∣kes comes to the linenge of the center everie way, beginenge firste wi∣the the right flanke of the center which is 7. and say the linenge of pikes of that flanke is 7. rankes of 3 pikes in eache ranke, and iuste so many more rankes for the linenge of the leift flanke of the center, conteinenge 21. pikes in each linenge, so by youre division youe fouu∣de the 2. linenges of pikes of the 2. flankes of the center. Nowe say 7. the front of the center and 6 the 2. linenges of the same maketh. 13. the front of the center and 2. lininges, nowe say that the thirde mani∣ple of unarmed pikes that shall line the front of the center and the 2. linenges of the same, shall marche witth 13. rankes of 3. drie pikes in each ranke, so the 2. flankes and front of the center are linde: that don say that the 4. maniples of unarmed pikes are to be divided into 13. rankes of 3. pikes in each ranke for to line the rergarde of the

void center, and say that the center is proportionally lined everie way withe the unarmed pikes, and that one unarmed pike did remaine in youre laste division.

Nowe to divide the armed pikes, to line the unarmed proportio∣nally every way, take the full number of the center, of the unarmed, and armed pikes propounded, which 3. partisiones dothe amonthe 342. that don take the square roote of this number which wilbe 18. and resteth 18. of the which 17. are armed pikes and 1. 〈 math 〉〈 math 〉 unarmed, nowe substract the square roote 13. oute of the square roote 18. and there shall reste 5. this 5. divide and say that 3 comes to line one way, and 2. armed pikes the other side of youre unarmed pikes; then say that the firste division of armed pikes that shall line the right flanke of the unarmed, muste march withe 13. rankes of 3. armed pikes in each ranke which dothe amonth to 39. so say that the right flanke of the unarmed is lined with corseletes, nowe in the seconde division of corseletes shall march 13. rankes of 2. armed pikes or cor∣seletes in each rancke to line the leifte flanke of the unarmed as by youre division so fallethe oute, nowe say that the 2 flankes of the unarmed pikes are lined with the corseletes. Then in the third division of the corseletes shall march 18. rankes of 3. corseletes in each ranke for the linenge of the full front of the unarmed pikes, and cēter. That don cause the fourth division or maniple of corseletes to marche wi∣the 18. rankes of 2. corseletes in each ranke for the linenge of the rer∣garde of the battell so say that the voide center is proportionally lined withe the unarmed pikes, and the unarmed withe the corseletes, and that there did reste 18. pikes whiche shall serve to guarinsh the cou∣lors in the center, advertisinge that 17. are corseletes and 1. unarmed pike all which diuisiones youe se ordered as by the figure followinge apeereth; nowe to divide youre propounded number of shott which was 352 musketes take the full number of the center of the armed and unarmed pikes, as also of the musketes whiche will amonte 694 oute of whiche take the square roote whiche will by 26. oute of whiche substracte 18 the square of the center of the armed and unarmed pikes, and there shall reste 8. this 8 divide into two par∣tes and eache parte will by 4 and say that to guarinshe the righte flan∣ke of the squadron of pikes youe are to marche withe 18. rankes of 4. musketes in eache ranke, and withe iuste so many more shall youe guarnishe or line the leifte flanke of the full number of pikes, nowe to

finde oute the lininge shott of the frōte and rerwarde, say that adinge to 18. the fronte of the pikes 8 of the two linenges of the two flan∣kes it makethe 26. and then say that to guarinshe the full fronte youe are to marche withe 26. rankes of 4 musketes in eache ranke, whiche is the lininge shott of the fronte, and iuste so many more rankes shall guarnishe the rerwarde of the battell of pikes meaninge 26. rankes of 4. musketes in eache ranke and so is youre battell proportionally lined every way as the figure and divisiones folowinge sheowethe.
