A comic epic in ottava rima about Juan, a handsome young Spaniard who is more seduced than seducing. Sent away from Seville after an affair with a married woman, he survives shipwreck, falls in love with a pirate's daughter on a Greek island, is sold as a slave in Constantinople, fights for Russia, wins Catherine the Great's favour and lands among the English aristocracy, while the narrator digresses on everything.
