Vitalis of Blois was a 12th-century cleric and Latin dramatist. He wrote two elegiac comedies, Geta and Aulularia, both adaptations of Plautus. The internal evidence of his plays shows him to have been highly educated. His writing can be dated to 1150–1160 at the earliest. The earliest manuscripts date from later in the century. His surname appears in the Latin sources as Blexus, Blesis or Blesensis, indicating an association with Blois. References to Plato in his work suggest a connection with the school of Chartres, where Plato was much admired at the time.
