I went through the day in a bizarre, stomach-curdled funk. I had a vague headache, my eyes were blurry, my temper did not exist, and I couldn’t really sleep. I blamed everything and everyone. Sometimes I had to fight back tears. I had intended another odyssey in search of a certain coffee shop. That didn’t happen. Instead, I… sat. I tried to sleep. I read. I gritted my teeth. I forgot to eat. Eventually, set out by a book on Krakatoa that I have been reading, spot in spot, in the bathroom, I began researching things on The Internet.

In that book, I had come to a passage mentioning a claim a few years ago, in a British documentary, that an early explosion of Krakatoa, in 517 or thereabouts (early sixth centry, anyway) was in part responsible for everything from the fall of the Roman Empire to the Dark Ages to the Plague of Justinian.

This got me to wondering about the “Dark Ages”. The implication that the period could have been brought about by environmental factors, such as those that come after such an eruption… well, it perplexed me. So I pulled up Wikipedia and typed in “Dark Ages” — to find nothing terribly illuminating. Since I was up for a refresher on Charlemagne, however, I followed that thread. This brought me to the revelation that Charlemagne’s father, Pepin, was responsible for the revival of a system of coinage in the land formerly covered by the Western Empire. That system, inspired by the original Roman model, was as follows:

1 libra = 20 solidi = 240 denarii

How… oddly familiar. The math was just bizarre enough to force me a double-check on the pre-decimal system for Pounds Sterling. And what do we have here.

The “L” for pound comes from Libra; the “S” for shilling comes from Solidi, and the “D” for Penny comes from Denarii.

It’s the same thing. In at least some form, the original Roman system persisted until 1971, before progress made its blow.

This revelation led me to other topics. Those, to others. Hours later, I feel… fed.

Now, I may sleep.
