Of Cabbages and Celts
The word "cabbage" is an Anglicized form of the French caboche, meaning "head." It has been used, loosely, to refer to loose-heading (or even nonheading) forms of Brassica oleracea as well as to the modern hard-heading type classified as B. oleracea variety capitata.
The Celts of central and western Europe had much to do with the distribution and popularization of cabbage as a food plant. Although the evidence points to the eastern Mediterranean and Asia Minor as the place of origin of the species, Celtic knowledge of it was so ancient as to have influenced the Latin name, Brassica (from the Celtic word bresic, meaning "cabbage").
Introduction of "cabbage" into Europe has been generally ascribed to the Romans, but it seems probable that the Celts introduced it even earlier. The Celts invaded Mediterranean lands repeatedly from about 600 B.C. to the beginning of the Christian Era, reaching into Asia Minor around 278 B.C. They also reached into the British Isles in the fourth century B.C. Shortly before the beginning of the Christian Era the Romans spread into northern Europe and into Britain.
In view of those movements, it is not surprising that the history of the development of the cabbagelike group of vegetables has been confused between the Mediterranean or Asia Minor, on the one hand, and northern and western Europe on the other.
Most of the European and Asiatic names for cabbage can be traced to one of three Celtic or part-Celtic root words. Kopf Kohl (German), cabus and caboche (French), cabbage (English), kappes, kraut, kapost (Tartar), kopi (Hindu), and others, all are related to the Celto-Slavic cap or kap, meaning "head." Kaulion (Greek), caulis (Latin), kale (Scottish), kaal (Norwegian), kohl (Swedish), col (Spanish), are related to the Celto-Germanic-Greek caul, meaning "stem."
