A Louisiana historian will retrace the steps of a slave who moved through the state in a presentation Tuesday at Nicholls State University's Ellender Memorial Library.

Starting at 1:30 p.m., Meredith Melancon will discuss Solomon Northup's journey from New Orleans to Rapides Parish to Avoyelles Parish.

The presentation is part of the traveling exhibit "Purchased Lives: The American Slave Trade from 1808-65," which is on display at the library until Oct. 13. The Historic New Orleans Collection and the Louisiana Endowment for the Humanities produced the exhibit.
