What are examples of allusions in the princess bride?

The allusion to swashbuckling adventure tales, but there are more very direct references. William Goldman alludes to a famous scene from his own screenplay for Butch Cassidy and the Sundance Kid where they escape from a pursuing posse by jumping off a high cliff into the rushing river rapids below as the inspiration for that famous scene in The Princess Bride in which the situation is the exact reverse. Inigo, Fezzik and Vizzini attempt to escape a pursuing figure by climbing up a high cliff from the waters below.
