The head of the breach or separation, as the Land’s End is from
Scilly. (Dr. Pryce.)
From its Court House, on the promontory, called Penwith or Land’s End;
and this promontory, so called as Dr. Pryce thinks from Pen, and With
the head of the separation from Scilly; but rather as With (says
Nennius) signifies Divortium, and means the Isle of Wight, the
headland of the Isle opposite, just as this very promontory was called
by the ancients Anti Vesteeum, the point opposed to Vesteeum.
