Titivillus mordederit,

mala morte moriatur,

in sartagine coquatur,

instent eum in febres

et rotetur

et suspendatur.

Amen.

Titivillus was a demon said to work on behalf of Belphegor, Luciferor Satanto introduce errors into the work of scribes. The first reference to Titivillus by name occurred in Tractatus de Penitentia, c. 1285, by Johannes Galensis, John of Wales. 
Titivillus has also been described as collecting idle chat that occurs during church service, and mispronounced, mumbled or skipped words of the service, to take to Hell to be counted against the offenders.
