Black Death Predated 'Small World' Effect, Say Network Theorists 168
KentuckyFC writes "Epidemiologists know that modern diseases can spread almost simultaneously in different parts of the planet because an individual who becomes infected in Hong Kong, for example, can infect friends in New York the following day. This is known as the small world effect. It is the same property that allows any individual to link to another individual anywhere in the world in just a few steps. But in the 14th century, the Black Death spread in a very different way, moving slowly across Europe at a rate of about 2 kilometers a day. Now network theorists have simulated this spread and say it is only possible if the number of long distances travelers in those days was vanishingly small. In other words, people in medieval society were linked almost exclusively to others nearby and so did not form a small world network. That raises an interesting question. If society in 14th century Europe was not a small world but today's society is, when did the change occur? The researchers say the finger of blame points to the invention of railways and steamships which allowed large numbers of people, and the diseases they carried, to travel long distances for the first time."

For the peasants who made up the majority of the population during the 14th century, a horse was a good tool for farmers or messengers, but regular travel would best be done on foot with a light pack and a steady pace.

We obviously could have done alot more with a light pack. And again, we were not in shape, didn't train, and most had never even
been backpacking before. For endurance running a human is every bit as good as a single horse. The pony express used multiple

Almost nobody had horses back then, compared to the 19th century. Working the land was done manually, or with the aid of oxen and such. Horses were more or less used as battle transportation and sometimes very important couriers. There was occasional other use for them, but horse ownership was usually reserved to the nobility and rich cities due to the cost of maintenance in the times that the black plague was hitting Europe.
Keep in mind that the black plague was spread by fleas that favoured rats, cats, dogs and such as hosts. They would choose humans as hosts, but were repelled by horses and their smell. As such, people that lived in horse staples and worked with horses, or rode them to the next town, most often were spared. If a lone person travelling on horse back would come from an infested city and was not bitten by an infested flea by the time he left that city, he wouldn't be carrying any infested fleas or the bacteria by the time he arrived in the next town. The spread of the virus might have actually occurred without any human interaction whatsoever in a lot of cases where fleas just infected rodents living in the wild, or actually by people that travelled by foot and brought their dogs and such along.

Nice, "pro-Nabatean" writeup on the late-antique origin of Arab maritime trade, after the breakup of Alexandrian east. You will have to go farther back, to the Phoenicians of Tyre and Carthage, 'tho! This author begins with Nabatean emergence. There are many links on this site... Quite fascinating.

Oman and maritime history. Nice to overlay this with the Nabateans. These things met and mingled - especially out in the Indian ocean, away from home:

The sections on Ancient Indian and Chinese maritime development is slim, but worthwhile:

There probably were a lot more of these travellers than we know of... anyone who didn't keep a journal, or show up in someone else's preserved writings, is lost to history.

I'm sure that these were often lost in the destruction of Baghdad, and other catastrophes to the world's written record. Also, the labouring seamen - who were mostly unlettered. But of accounts, there are still many such, from the Muslim world, between the rise of the Ummayids, and the destruction of that world by the Mongols and the plague.
There was a very high level of literacy in Islam, which had leveled most aristocratic social structures and replaced those with scholastic meritocracy - in general, if

The wide distribution of silk merely implies that there was some trade -- it doesn't imply at all that the markets weren't so thin that a single caravan's choice of whether to travel or not didn't control the availability of new silk for year(s) at a time. Try reading Hakluyt's voyages some time -- organizing even a single successful long distance trading caravan was not an easy operation.
I think one thing that people often forget about the great steam age of transportation, is that the flows of people were

Rats. Crusades. Trade.
They had Silk in freaking Budapesht, Kiev, Oslo, Bruges, Orleans, Stuttgart and Florence. How isolated do you think the world was?
I think the point was, it's not the distance, it's the speed and frequency.

This author is astonishingly ignorant. There was a bigger bubonic plague outbreak in the 7th century in Constantinople. It spread to...
central and south Asia; North Africa and Arabia;[citation needed] and Europe all the way to Denmark and Ireland
(thanks wikipedia), and its suspected to have originated in China or in Egypt (a lot of wheat was imported from there).
This meme that somehow the world wasnt "globalized" until the 19th century is hilarious, and wrong.

The Justinian Plague was a big one, no doubt about that. What it's causative organism was is rather less clear. Bubonic Plague has certainly been put in the frame, but I don't think that the case has been closed.
Oh, sorry, I see that the case has been pretty much nailed shut in the last few years. I withdraw my objection.

It's ridiculous that you need researchers to tell you that spreading disease became more easy with rail technology or with long distance shipping. I mean, what have they revealed that we didn't already know?

They have revealed that high speed long distance travel was not common before it was possible. Who would have guessed?
