Ever wonder how the realistic yet fictional languages in your favorite films and shows are created? Linguist and author David Peterson, who is best known for creating the Dothraki and Valyrian languages for HBO's "Game of Thrones," will explain on Wednesday, April 13, at the University of Rochester. Peterson's lecture, "New Media Linguistics: Developing Languages for Game of Thrones," will be held in the Hawkins-Carlson Room in Rush Rhees Library at 6 p.m.

Peterson has developed languages for a number of films and television series, including for Syfy Channel's "Defiance" as well as the language used by the Dark Elves in the movie, "Thor: The Dark World." His talk will provide insight into the process of languages creation, and explore the cultural, historical, and linguistic aspects that are taken into account when inventing a new language. The lecture is free and open to the public, and free parking is available in the Library Lot. For more information, call 275-4461, or visit sas.rochester.edu.
