Renaissance history is so much wilder and weirder than you would have expected.
Very fun chatting with Ada Palmer [https://www.adapalmer.com/] (historian,
novelist, and composer based at the University of Chicago).
Some especially fascinating things I learned from the conversation and her
excellent book, Inventing the Renaissance [https://a.co/d/03EjyByR]:
Not only did Gutenberg go bankrupt in the 1450s (after inventing the printing
press), but so did the bank that foreclosed on him, and so did his apprentices.
This is because paper was still very expensive, and so you had to make this big
upfront CAPEX decision to print a batch of 300 copies of a book - say the Bible.
But he’s in a small landlocked German town where only priests are allowed to
read the Bible - so he sells maybe 7 copies. It’s only when this technology ends
up in Venice, where you can hand 10 copies to each of 30 ship captains going to
30 different cities, that it starts taking off.
Speaking of which, the printing revolution wasn’t just one single discrete
event, just as the computer revolution has been this whole century of going from
mainframes -> personal computers -> phones -> social media, each with different
and accelerating social impact. Books came first, but they’re slow to print, and
made in small batches. The real revolution is pamphlets - much faster, much
harder to censor. Pamphlet runners are how you can have Luther’s 95 Theses go
from Wittenberg to London in 17 days.
So much other wild stuff from this episode. For example, did you know that the
largest and best-funded experimental laboratory in 17th century Europe was very
likely the Roman one run by inquisitors? Ada jokes that the Inquisition
accidentally invented peer review. The focus of the Inquisition is really
misunderstood - it was obsessed with catching dangerous new heretics like
Lutherans and Calvinists - it only executed one person for doing science.
And this leads Ada to make an observation that I think is really wise: the
authorities and censors are always worried about the exact wrong things given
20/20 hindsight. When Inquisition raids an underground bookshop during the
French Enlightenment, they don’t mind the Rousseau, Voltaire, and Encyclopédie,
but they lose their minds about some Jansenist treatises about the technical
nature of the Trinity.
More broadly, a lesson for me from this episode is that it’s just really hard to
shape history in the specific way that you want to impact things. One of the
most famous medieval scholars is this guy Petrarch. He survives the Black Death
in the 1340s, watches his friends die to plague and bandits, and says: our
leaders are selfish and terrible, we need to raise them on the Roman classics so
they’ll act like Cicero. So Europe pours money into finding ancient manuscripts,
building libraries, and educating princes on classical virtues. Those princes
grow up and fight bigger, nastier wars than ever before with new deadlier
technology. And this, combined with greater urbanization and endemic plague,
results in European life expectancy decreasing from 35 in the medieval period to
18 during the Renaissance (the period which we in retrospect think of as a
golden age but which many people living through it thought of as the
continuation of the dark ages that had persisted since the fall of Rome).
Anyways, the libraries Petrarch inspires stick around, the printing press makes
them accessible to everyone, and 200 years later a generation of medical
students is reading Lucretius and asking “what if there are atoms and that’s how
diseases work?” which eventually leads to germ theory, vaccines, and a cure for
the Black Death (Ada has longer more involved explanation of how cosplaying the
Romans results through a series of many steps to the scientific revolution).
Petrarch wanted to produce philosopher-kings that shared his values. Instead he
created a world that doesn’t share his values at all but can cure the disease
that destroyed his.
