 The modern use of "Caledonia" in English and Scots is either as a historical description of northern Britain during the Roman era or as a romantic name for Scotland as a whole.Ptolemy's referred to the "Caledonia Silva", recalled in the modern expression "Caledonian Forest", although the woods are reduced today compared to the Roman times.This association with a "Silva" (literally the flora) reinforces the idea that Caledonia was a forest or forested area named after the Caledonii.
