Note 342 — THE AUXILIA DURING THE FIRST TWO CENTURIES A.D. (continued 2)
Reading edition
The palisade was not, of course, a board fence which could be torn down in a few minutes. It was made of oak-trees split in halves and bedded in a ditch four and a half feet deep. See Pelham, op. cit., p. 200. Some idea of its appearance can be gathered from the representation at the beginning of the reliefs on the Marcus column.
