Note:
In addition to RIC VI's description of Nicomedia passing into the control of Galerius from 305 CE and presumed to remain so until his death (pp.546-549), Omissi and Lindholmer argue for the sharing of territory by Augusti Galerius and Licinius from 308 CE. In further support of this dual assignment see T. Barnes, The New Empire of Diocletian and Constantine (London, 1982), p.197-198.
