Mercedarian friar. Worked with Saint Ferdinand of Portalegre. In 1253 the two sailed from Barcelona, Spain to Tunis in North Africa to ransom Christians imprisoned and enslaved for their faith by Muslims. By 16 October 1253 they had free 129 but were double-crossed by some of the slave traders and turned over to Muslim royal authorities. Ferdinand was eventually released and ordered to leave the country with his ransomed slaves, but Theobald was tortured and executed. Martyr.
- thrown into a fire, and when he did not die quickly enough, he was stoned to death in 1253 in modern Tunisia
