Britannia

Britannia, the Roman name for the British Isles revived by Camden (1586), has become the poetic name for Britain. Personified as a seated female figure, she appeared emblematically (modelled by Frances Stewart) on Charles II's 1667 peace of Breda medal and copper coinage (1672); the ‘union’ shield resting alongside bore the crosses of St George and St Andrew.
