Historia Apollonii Regis Tyri

Apollonius of Tyre is the subject of an ancient short novella, popular during medieval times. Existing in numerous forms in many languages, the text is thought to be translated from an ancient Greek manuscript, now lost. The earliest manuscripts of the tale, in a Latin version, date from the 9th or 10th century; the most widespread Latin versions are those of Gottfried von Viterbo, who incorporated it into his Pantheon of 1185 as if it were actual history, and a version in the Gesta Romanorum. Shakespeare's play Pericles, Prince of Tyre was based in part on Gower's version, with the change of name probably inspired by Philip Sidney's Arcadia. Apollonius of Tyre was also a source for his plays Twelfth Night and The Comedy of Errors. (Summary by Wikipedia)
