patrols.100 (The coin-pat tern sugges ts that th is activity involved troops
from the Upper Rhine: the garrison on the High Rhine and upper
Danube was secure behind the Danube–Iller–Rhine limes.101) None of
this amounted to a full re-establishment of Roman control. There are
signs of the pragmatic securing of key areas, but no more. Against
Stribrny, there is no convincing epigraphic or literary evidence for the
restoration of Roman administration in Alamannia.102
Low-key imperial military presence in western Alamannia may
have been reinforced by exploitation of the region’s resources. The
most dramatic evidence we have of this comes from Trier cathedral.
Here, a major refurbishment of the building, planned around 330
but completed only later in the century, led to the commissioning of
four massive granite pillars (each c.12 metres long and weighing
30 tonnes) and marble capitals. The complete set came from quarries
over the Rhine to the east of Worms, near Reichenbach, in the
Felsberg (or ‘Felsenmeer’). The working of such quarries and the
transporting of their products into the Empire must have required
the long-term presence of signiWcant numbers of people—engineers,
labourers, supervisors, guards, and ancillary personnel. 103 Those who
were not slaves would have been paid, and so have attracted a further
set of people oVering goods and services. In this way, coinage would
have been circulated and lost. In addition to stone, we may envisage
the collection of other raw materials for export into the Empire.
Ammianus Marcellinus and Libanius indicate that Alamannic terri-
tory was a good source of building timber. Equally suggestive, in the
light of archaeological evidence for widespread working of the metal,
is Libanius’ report that Julian compelled Alamanni to provide
him with iron.104 Ammianus’ knowledge of the dispute between

11737) are unoYcial and, to judge from their form and content, were probably
erected before 260. The Victorinus leaguestone at Illingen is generally accepted to
have been erected on the west bank of the old Rhine: Drinkwater (1987: 121).
Generally, Stribrny puts too much trust in the Historia Augusta .
