Sacrifice of Sybil

Scene taken from Terry Pratchett's Discworld novel "Guards, Guards", where Sybil Ramkin is about to be given to the dragon as a virgin sacrifice.
The heroic Captain Sam Vimes of the Night Watch is the only person who lifts a finger to go and rescue her, when it is later discovered that the dragon was female and therefore didn't want her anyway - it just wanted to mate with Errol, one of her swamp dragon's.
