&
anterides cortinæ æquipollent dua- bus tertiis earum quæ ad latus:
debentq́;
ita deſignari, vt duobus aut tribus pedibus longiores &
latiores ſint iis quæ deſignabuntur ſupra primam plateam:
intere- ritq́;
inter eas ſpatium decem vel duodecim pedum.
Præterea hæ omnes menſuræ augeſcent aut minuen- tur pro ſitus varietate, &
habita ratione impenſarum quas in iis facere voluerimus.
Deſignatis ſupradictis anteridibus, deſignabuntur pilæ lapideæ intus quan- tum ſtatuetur
primas plateas apertas eſſe:
deſignabun- turq́;
intra primas plateas 20 pedes, vt ſuprà dictum eſt, duobus aut tribus pedibus longiores
&
latiores quàm eæ quæ ſupra primas plateas:
eaq́ lege deſcri- bentur, vt quum fabricatæ fuerint aduſque primas plateas, &
à primis aduſque ſecundas, bombardæ pri- mæ plateæ non impingant in dictas pilas.
Deſignatis pilis deſignabuntur alæ propugnaculi, ea conditione vt quum fabricatæ fuerint
aduſque primas plateas &
fupra eas, æquè diſtent quatuor aut quinque pedibus à retroceſſionibus bombardarum, quæ
ſunt in pri- mis plateis, quæ ſcilicet ſunt in duabus primis feneſtris tormentariis:
quia ſi retrocedendo bombardæ in mu- ros impingerent, compactio illa lignea, cui innitun-
tur, (Galli vocant attcſagc) omnino frangeretur ac diſ- ſolueretur.
Præterea deſignabitur murus ſpiſſitu dinis octo aut decem pedum, qui longitudinem
primarum platearum terminabit.
Hæc autem omnia apparent deſignata in ſequenti ſeptima figura, vt indicant litte- ræ
ſequentes.
