TIBURCE, Valerian's brother and Cecile's brother-in-law, is martyred for his faith (Legenda aurea LXIX).
Tiburce is converted through Valerian's teaching and becomes a Christian. He suffers martyrdom with his brother, SNT 242-409. [Almache: Cecile: Maxime: Urban: Valerian]
Tiburce apparently means "the man from Tibur," a famous resort for rich Romans at this time. Both names, Valerian and Tiburce, indicate that the brothers are from noble Roman families. Tiburce occurs twice initially, SNT 260, 302; nine times in medial positions, SNT 242, 265, 289, 307, 333, 348, 349, 354, 408. It never appears in final rhyming position. Tiburces, the ME genitive case, occurs medially, SNT 277.
