Sulpicius Alexander
Sulpicius Alexander was a Roman historian of Germanic tribes. His work is lost, but his Historia in at least four books is quoted by Gregory of Tours. It was perhaps a continuation of the Res gestae by Ammianus Marcellinus and dealt with events at least until the death of Valentinian II. The work of Sulpicius Alexander as extracts in Gregory's Decem Libri Historiarum is considered an important source in any discussion of the origin of the Frankish tribes.
