In the spatial geography of Pompeii we noted that the elite were spread
out across the town, intermixed with the rest of the populace (Wallace-
Hadrill 1990, 1991), partly so that social positioning could be reaffi rmed in
visibility and movement through the town; similarly the public buildings were
also spread out. However, in a fortress rank was not up for negotiation in the
same way and the spatial geography of the military elite’s residences and the
communal buildings is very different. The hierarchical divisions were made
clear in the living arrangements in the camps (cf. Johnson 1983). From the
earliest description of the layout of tents by Polybius (6.27–42) in the mid
second century BC, to the physical evidence of the stone-built fortresses of
the frontier several centuries later, we see these divisions enshrined in the
plan. While in Pompeii the members of the elite were dispersed amongst
the different town districts or vici, in forts they were zoned and clustered.
The via principalis was where all the principals of the offi cer and solider ranks
lived. Here were the six houses of the Senatorial and Equestrian tribunes,
all located near to the heart of the camp, the principia and praetorium. Even
the centurions of the fi rst cohort (the most experienced soldiers) were given
more lavish quarters and placed along this street. The picture here is radically
different from the dispersed elite of Pompeii.
We can see all this in the layout of the legionary fort at Caerleon (Figure 4.2).
Here the only member of the elite not to live directly on the via principalis was
the legatus legionis himself, here situated in his palatial resid ence just behind the
principia. The principia was where the standards of the legion were kept, and
the strong-room. Originally, in temporary camps under canvas, this was an
open area in front of the praetorium, or Legate’s tent. In this arrangement the
commander’s residence had been the principal focal point of attention. As
time went on, and Roman military architecture developed, this focus shifted
to the aedes in the centre of the principia, where the legionary standards were
kept. This subtly shifted the focus of loyalty away from the commander to
images relating to Rome and the Emperor (Blagg 2000). Caerleon, for its
date, is perhaps a slightly archaic example. The Legate’s palace is still situated
behind the principia in its original position. In many other fortresses con-
structed around this date, and certainly later, the praetorium has often been
located along the via principalis, alongside rather than behind the praetorium.
This means all the upper elite of the fortress now lived along the main road,
with the rank and fi le being tucked behind.
After active service, the Senatorial and Equestrian elite will largely have
gone home, though one tombstone in Colchester attests to one who did not
make it (RIB 202). However, the way of living that will have become embed-
ded in the minds of the veterans will have included the idea of hierarchical
residential zoning. In the main, all the key buildings were clustered in one
place, generally the middle of the fort. They would have gained no experience
of the notion of procession from different locales to the forum and baths,
though they would have had alternative parade drills. Baths differed a bit in
