Caesar - Gallic War - Book VII, 23 - Walls
All Gallic walls are, as a rule, of the following pattern. Balks are laid on the ground at equal intervals of two feet throughout the length of the wall and at right angles thereto. These are made fast on the inside and banked up with a quantity of earth, while the intervals above mentioned are stopped up on the front side with big stones. When these balks have been laid and clamped together a second course is added above, in such fashion that the same interval as before is kept, and the balks do not touch one another, but each is tightly held at a like space apart by the interposition of single stones. So the whole structure is knit together stage by stage until the proper height of wall is completed. This work is not unsightly in appearance and variety, with alternate balks and stones which keep their proper courses in straight lines ; and it is eminently suitable for the practice defence of cities, since the stone protects from fire and the timber from battery, for with continuous balks, generally forty feet long, made fast on the inside it can neither be breached nor pulled to pieces.
