Cornwall: The ancient British name of this country was Cernyw, a name probably received from the Latin cornu, "a horn." The Romans, who traded here for tin, called it Cornubia, which name it bore until the Saxons imposed the name of Weales upon the British who retreated into the fastnesses west of the Severn and the Dee. The latter portion of the name Cornubia was then dropped, and the word Wales substituted, forming the name "Corn-Wales," of which the present Cornwall is a corruption.
