Note 223 — Chapter VII · THE PERIOD OF TRANSITION: CYLINDRICAL TOWER-KEEPS
Reading edition
A bartizan is a small turret or lookout corbelled out at an angle of a tower or on the surface of a wall. The word is connected with “brattice” (bretèche); and such turrets, like the machicolated parapet, are the stone counterpart of the bratticing and hoarding of timber applied to fortresses at an earlier date.
