This quote from a conclavist to Cardinal Ferrieri in the conclave of Leo XIII says a lot about the process. I love the last sentence.
The Germans are on his side as will be the Spanish tomorrow because Franchi has now sided with Pecci; Howard, who up to now has voted for Simeoni, will vote for Pecci tomorrow; as I’m sure Your Eminenccy is aware, Bilio declared to Barolini that if he were to be elected he would not accept, for he considers it a heavy burden; Monaco and Randi will continue to vote for Martinelli; Franzelin likes Monaco, but he is wasting his time: Your Eminency, you must accept the truth, God has chosen Pecci.
The quote is cited in The Papal Conclave: How do Cardinals Divine the Will of
God?. The author, J.T. Toman has collected voting data (from diaries etc.) of voting in many of the conclaves in order to produce a paper that combines econometrics, theology, and voting theory!
If that doesn’t sound like your cup of tea, perhaps you will enjoy Incredible Popeman, a new comicbook which "shows the late Polish pontiff meeting comic book
legends such as Batman and Superman to learn how to use superpowers to battle Satan."
Thanks to Daniel Strauss Vasques and Stan Tsirulnikov, respectively, for the pointers.
