Attested: AI iter 5 Caesaromago, iter 9 Cesaromago; RC Cesaromago; TP Baromaci
Where: Chelmsford, Essex, around TL709062.
Name Origin: Caesar- is obviously Roman, while –magus became a common place-name element across the Empire whose exact significance is disputed. Celtic words such as Gaelic machair ‘grassy plain’ are often cited to suggest a market place developing on open land, but more likely *magus meant something like ‘power place, administrative centre’, from PIE *magh- ‘to have power’. See Udolph (2012:45-8) for how this element developed in areas around the North Sea and led to names such as Magdeburg. See also Magis about a possible development of Latin magis ‘platter’ towards ‘town square’.
Notes: Caesaromagus began as a Roman fort established close to the tribal centre of the powerful Trinobantes and had a twin on the Continent at modern Beauvais, in territory of the powerful Belgic tribe the Bellovaci.
