tasks were Wt only for the unfree) reasons. However, given the low level
of population, such slaves were not present in massive numbers. Even
less numerous, but equally signiWcant, were the skilled outsiders who
served the elites of the hill-sites. In the later third century, such
outsiders may have been slaves, acquired through raiding and intro-
ducing new skills.144 In the fourth century, such people would have
been less accessible and recourse may have been had to dependent
freemen: we know of a much later Alamannic leader employing free
craftsmen.145
In the fourth centur y, free Roman craftsmen were available over
the Rhine. Indeed, it may have been that a number of these were
voluntary exiles, with no wish to return to Roman jurisdiction. In
other words, the exploitation of transrhenish resources may, in
opening up the Rhine frontier, have encouraged imperial emigration.
From what later writers, such as Salvian, say about deteriorating
social conditions in the west in the Wfth century, which drove the
desperate to Xee to the barbarians, there is the possibility that the
fourth century saw imperial migrants trickling into Alamannia,
escaping problems with landlords, tax-collectors, judges and recruit-
ing oYcers.146 It is signiWcant that legislation of Valentinian I recog-
nized the possibility that, in time of barbarian attack, people might
go over to the enemy of their own accord.147
Overall, we may envisage the population of Alamannia during the
fourth century as being a rich mix of Germanic warriors (Elbgerma-
nic and eastern), Roman provincials of various backgrounds and

technical expertise in the later third century—visible in the Haarhausen–Eßleben
‘experiments’—and attributes it to a single generation of Roman craftsmen, taken as
slaves in third-century raiding, who were unable to pass on their skills to succeeding
generations.

century Alamannic king, Feletheus, foolishly subjected bar barian goldsmiths brought
to work at court to unlawful arrest.

Germania 29.4, in the Wrst century the Agri Decumates were colonized in advance of
formal annexation by ‘all the riV-raV of Gaul’: levissimus quisque Gallorum.
