The Golden Ass by Lucius Apuleius

Novel first written in the second century A.D., in a translation first published in 1566. According to Wikipedia: The Metamorphoses of Apuleius, which St. Augustine referred to as The Golden Ass (Asinus aureus), is the only Latin novel to survive in its entirety. The protagonist of the novel may in fact be the author himself. His first name is revealed to be Lucius; at the end of the novel, he is revealed to be from Madaurus, the hometown of Apuleius himself. The identification of the protagonist as Lucius of Madaurus has led some scholars to posit that the narrator and the author are one and the same person.[4] The plot revolves around the protagonists curiosity (curiositas) and insatiable desire to see and practice magic. While trying to perform a spell to transform into a bird, he is accidentally transformed into an ass. This leads to a long journey, literal and metaphorical, filled with in-set tales. He finally finds salvation through the intervention of the goddess Isis, whose cult he joins.
