“ ICENI, in Britain. Tacitus is the only author who gives us the exact form Iceni. He mentions them twice. First, they are defeated by the propraetor P. Ostorius, who, after fortifying the valleys of the Autona (Aufona) and Sabrina, reduces the Iceni, and then marches against the Cangi, a population sufficiently distant from Norfolk or Suffolk (the area of the Iceni) to be near the Irish Sea. (Ann. xii. 31, 32.) The difficulties that attend the geography of the campaign of Ostorius have been indicated in the article Camulodunum. It is not from this passage that we fix the Iceni. ”
