They are mentioned as Mediomatricorum and Mediomatricis by Caesar (mid-1st c. BC), as Mediomatrikoì (Μεδιοματρικοὶ ) by Strabo (early 1st c. AD), as Mediomatrici by Pliny (1st c. AD), as Mediomatricos by Tacitus (early 2nd c. AD), and as Mediomátrikes (Μεδιομάτρικες) by Ptolemy (2nd c. AD).
The name Mediomatrici derives from the Gaulish *Medio-māteres (literally 'middle-mothers'), formed with medios ('in the middle, central') attached to matir ('mother'). It has been interpreted as the 'Mothers of the Middle-World' (i.e. between the sky and the underworld), or as 'between the Matrona (Marne) and the Matra rivers' (i.e. the mother-rivers).
The territory of the Mediomatrici comprised the upper basins of the rivers Maas, Moselle and Saar, and extended eastwards as far as the Rhine in the mid-first century BC. Ptolemy places the Mediomatrici south of the Treviri.
During the Gallic Wars (58–50 BC), the Mediomatrici sent 5,000 men to support Vercingetorix who was besieged in Alesia in 52. In 69–70 of the Common Era, their capital Divodurum was sacked by the armies of Vitellius, and 4,000 of its inhabitants massacred. The Romanization of the Metromatrici was apparently slower compared to their neighbours the Treviri.
