Young Surak was the name of a piece of art that was created by the Vulcan species. In 2270, on the homeworld of the Thorvan League of Planets, Romulan Commander Di'on Charvon discovered a breathtaking piece of masterwork art which matched that of Earth's David, Vulcan's Young Surak and even Romulus's Atavar. (TOS novel: The Fate of the Phoenix)

Presumably, it was a represetation of the philosopher and Father of Logic Surak during his younger years.
