Adjectivizing people

I think it's kinda funny how adjectives are made out of people's names. Most notably are the adjectival forms of the New Testament writers:

Matthew - Matthean
Mark - Markan
Luke - Lukan
John - Johannine
Paul - Pauline
James - Jacobian (remember, "James" is the Greek form of the Hebrew name "Jacob"
Peter - Petrine
Jude - Judan
