Perseus describes in his wedding speech how he beheaded Medusa, and how she came to have snakes in her hair.
Peruzzi
How Perseus came to behead Medusa, and how her head restored order to the worst wedding reception ever. In paint, of course.
Not just superb paintings, but one of the great visual tropes of Western art, and one of the best wedding speeches ever.
