Then on the Points A set off half the Angle of the Figure, to wit 60° (as you see in the Ta∣ble in page 38) and draw the lines OA and O A, so shall O be the Center of the Figure, and PC the Gorge, and AP the Capitals: then finish* 1.2 each Bastion at your own discretion, and the Work is finished as required.
