[1] They are mentioned as Aulercos and Aulercis, Cenomanis totidem [all the same] by Caesar (mid-1st c. BC),[2] Aulerci .... Cenomani by Pliny (1st c. AD),[3] as Au̓lírkioioi̔ oi̔ Kenománnoi (Αὐλίρκιοιοἱ οἱ Κενομάννοι) by Ptolemy (2nd c. AD),[4] and as Ceromannos in the Notitia Dignitatum (5th c.
[7] A part of the Cenomani or another homonym tribe settled in Cisalpine Gaul after the Celtic invasion of the Italian Peninsula in the early 4th century BC.
Their chief town was Vindinum or Suindinum (corrupted into 'Subdinnum'), afterwards Civitas Cenomanorum (whence Le Mans, and much later the Cenomanian geological age) and later Cenomani as in the Notitia Dignitatum, the original name of the town, as usual in the case of Gallic cities, being replaced by that of the people.
According to Arbois de Jubainville, the Cenomni of Italy are not identical with the Cehomni (or Cenomanni) of Gaul.
[11] William Smith adopts the difference, placing the peoples in two separate articles in his Dictionary of Greek and Roman Geography.
According to Livy, the Cenomani of Cisalpine Gaul arrived after the expedition of Bellovesus, led by Helitovius, and are credited with the foundation of Brixia, or Brescia, and Verona.
