Tiburtius Timeline and Summary

Immediately after Valerian asks Cecilia's angel that Tiburtius be converted, Valerian enters the room and notices the strong smell of flowers.
When Valerian explains where the smell comes from and explains the Christian faith to him, Tiburtius assents to its basic truth.
Tiburtius demands an explanation of how there can be Christ and God, leading to Cecilia's explanation of the Incarnation and Trinity.
Tiburtius joins Valerian in refusing to worship at the shrine of Jupiter.
With Valerian, he preaches at the home of Maximus the executioner, leading to the conversion of that household.
Tiburtius is martyred and buried with Valerian.
