Are there any examples of the Olympics appearing in literature?

Robert Browning wrote a poem called "Pheidippides" about the man in ancient Greece who ran from Marathon to Athens to tell Athenians that they had defeated the Persians. The poem reads in part, "So, when Persia was dust, all cried, 'To Acropolis! Run, Pheidippides, one race more! the meed is thy due!'" Browning's poem inspired the founders of the modern Olympic games in 1896 to include the marathon as one of the events. Further back in time, during the ancient Olympics, the Greek poet Pindar wrote fourteen Olympic Odes to celebrate victors in the games. 
A more modern account of the Olympics is included in Jilly Cooper's Riders, published in 1985. In this book, rivalrous horsemen compete at the Los Angeles Olympics, which were held in the summer of 1984. Finally, in James Patterson's Final Games, published in 2012, a killer is on the loose at the London Olympics of 2012.
