Alamanni and Franks, but this is not the case. We hear of individual
conXicts. Julian set the bandit-turned-mercenary-turned-Roman-
general, Charietto, who may have been Frankish, against Alamanni.145
Likewise, Gratian employed the Frank, Mallobaudes, as a general
against Lentienses.146 Mallobaudes later appears as a native leader,
slaying the Alamannic king, Macrianus, who, after facing down
Romans and Burgundians, perished while raiding into Frankish ter-
ritory. This shows how, once they were beyond imperial control,
Rome’s allies were quite capable of destroying each other.147
Beyond this, however, there are few signs of regular Franco-
Alamannic interaction during the fourth century. This could be an
artefact of the sources, but there are good reasons for accepting it is
an authentic historical phenomenon. Camille Jullian described
Franks and Alamanni as occupying two diVerent worlds, separated
by the Taunus and the Main.148 Frankish ethnogenesis, by which is
meant the crystallization of Franks around Salian leaders of the
Merovingian dynasty, was less rapid than Alamannic; and its centres
were relatively far north, around Cologne and, for the Salians, in
Toxiandria by the Lower Rhine.149 The Franks were also probably
isolated from Alamannia by continuing Roman interest in the area
over the Rhine from Mainz.150 Macrianus’ attack on the Franks was,
presumably, from north of the Main, after his exclusion from south
of the river.151 On the other hand, Macrianus’ activities show that
such isolation was not absolute, and the existence of north–south
routes across the Taunus is indicated by the location of Augustan
military operations and bases.152
More important during the fourth century was another group
of people, described as positively hostile to the Alamanni, the
