Titivillus is the Demon causing typos and mistakes amongst writers, copyists and scribes. Also known as Tutivillus, Tytivillum, Tintillus, Tantillus, Tintinillus, Titivitilarius, Titivilitarius, though these might be typos.

Titivillus appeared in the Middle Ages, first as a Demon that collected in a large bag the idle chat and thoughts of people during Mass to give them to the Devil. He also collected the mumbled or skipped syllables of priests.

He seems to have specialized in the written word after the invention of the printing. Titivillus is particularly active in the religious realm and induces typos in the Holly Book. Famous successes of Titivillus include:

1562: The second edition of the Geneva Bible, Matthew 5:9[6] reads “Blessed are the placemakers: for they shall be called the children of God“; it should read “peacemakers“.

1717: Clarendon Press Bible: The chapter heading for Luke 20 reads “The Parable of the Vinegar” instead of “The Parable of the Vineyard.”

1653: “Know ye not that the unrighteous shall inherit the kingdom of God” (I Corinthians 6:9).

1792: A Bible printed in Oxford, England in 1792 has the very unusual substitution of the name “Philip” is made in place of “Peter” as the disciple who denied Jesus in Luke 22:34.

1831: the English royal printer Robert Baker reprinted the KingJames Bible with one typo in the 10 commandments: Thou shall commit adultery.
