In Spenser, a Queen of the Amazons.

She hated knights and imprisoned and humiliated them at every opportunity. Sir Artegall learned of this injustice and set out to slay her. He challenged her to single combat and defeated her, but when he wrenched off her helmet to behead her, he was overcome by her beauty. Radigund regained herself, and she captured and imprisoned Artegall.

Artegallís paramour, the warrior maiden Britomart, heard of his plight, went to the Amazonsí kingdom, killed Radigund, and freed Artegall.
