In ancient Rome, Diva Drusilla Panthea was the name under which the emperor Caligula deified his favourite sister, Julia Drusilla (16-38), after her death at age 21. This name was also borne by a mistress of Roman co-emperor Lucius Verus (130-169).
In theatre, it was used by Beaumont and Fletcher for a princess in their play A King and No King (1619) and by Percy Bysshe Shelley for an Oceanid in his play Prometheus Unbound (1820).

Panthea Vyne was the titular lady in the television film The Lady and the Highwayman (1989), based on Barbara Cartland's historical novel Cupid Rides Pillion (1952).
