The Short Guide to Catholic Church History discusses some of the more interesting ancient heresies:

1. Econophanic Heresy • An economic-based belief there was a Treasure House of Sin in addition to the Treasure House of Grace, "drawn on by the Devil and his angels;" called an 'aberrant fantasy." The sect of Econophanes eventually became demonic and collapsed when "word got around that a run on the bank had occurred"
2. Monophonic Heresy • A belief that the Heavenly Host sings with one voice and not with many hierarchically arrange voices. Sector of Rheims, known as "the Flawless Thinker," was a skeptic of this heresy.
3. Scrupularian Heresy • A belief that asked if one sin repeated all day was one big sin or many tiny sins. Orduri della Vacca, a fifteenth-century proto-seminalist, was the originator of this heresy. Pedasculus, his disciple, said "time is infinitely divisible and subdivisible, there are as many sins as there are moments of time." Father Widdershins, O.P. was a skeptic of the heresy.

Names

• Orduri della Vacca • translates to "manure of the cow" or "cowshit."
• Pedasculus • may roughly be interpreted as "little pedant."
• Widdershins • An old English word meaning to go in a counter-clockwise circle around something (considered to involve black magic or to induce bad luck), explains Bowen. "Celtic tradition required going 'sunwise' (i.e. clockwise) around things unless you wanted to lose your luck. From a number of warrior tales I think the ultimate reason is that, when you turn your right (spear or sword) side toward someone, you are not covering yourself with your shield, which is borne on the left arm, so that a right-handwise approach is nonhostile. If you turn your shield toward someone coming toward you, you are preparing to fight with him." The O.P. indicates the Dominican order; the Latin words for "Order of Preachers."

The line about Vallombrosa is a well-known quotation from John Milton in Paradise Lost (i, 302).
