The term pre-Surak was used to denote items from Vulcan culture that predated the new era in Vulcan culture ushered in by Surak.
In 2373, a pre-Surak bracelet that was recovered from an old derelict freighter was auctioned off on Deep Space 9. (DS9: "In the Cards")
This period would have ostensibly ended during the 4th century.
