The Survey of Cornwall (Illustrated‪)‬

Cornwall, the farthest Shire of England Westwards, hath her name by diuers Authors diuersly deriued. Some (as our owne Chroniclers) draw it from Corineus, cousin to Brute, the first Conqueror of this Iland: who wrastling at Plymmouth (as they say) with a mightie Giant, called Gogmagog, threw him ouer Cliffe, brake his necke, and receiued the gift of that Countrie, in reward for his prowesse: Some, as Cerealis, (no lesse mistaken perhaps in that, then in his measures) from Cornu Galliae, a home or corner of Fraunce, whereagainst nature hath placed it: and some, from Cornu Walliae, which (in my conjecture) carrieth greatest likelyhood of truth.
