Vortipor, Vortiporous

The third King of Britain after Arthur, according to Geoffrey of Monmouth.

Vortipore succeeded to the throne after the previous wicked king, Conan, fell off a horse and broke his neck. Vortipore successfully battled off a wave of Saxon invaders and reigned for seven years. Vortipore is a historical figure, though the position attributed to him by Geoffrey is invented.

Gildas mentions him as a tyrannical king of Dyfed (Demetia), which he apparently inherited from his father, Agricola. Vortipore had a great-grandson named Arthur of Dyfed.
