W is for Wind

…The North wind is the wind of satisfaction,
the South wind overthrows the men it hits,
the East wind is the wind that brings rain,
and the West wind is mightier than the man living there.

Sumerian proverb, @1900 BCE.

In our alphabetic journey through Ancient Inventions, we are now into the last four letters, so I feel a bit of wind at my back. Which is good, since Wind is today’s topic–specifically, wind power and how ancient people used it.

In yesterday’s post on Valves, I described how ancient civilizations developed plumbing in order to control water. It is in the DNA of Homo sapiens–all the hominids–control the environment. We have always wanted to mold the world as we wished. What separated primates and apes in particular from other animals is tool use, and what seemed to caused hominids evolution was tool upon tool upon tool use. Fire-arrows-wheels-axes-thread-carrying slings all reflect continuous adaptation. We change things in the world to suit our needs until we try to shape the world into a tool for ourselves. This was modest 10,000 years ago with stone towers and calendars; bigger by the time of the pyramids, 5000 years ago. As of 2025 CE, it may be an experiment gone too far, now that the environment is fighting back.

However, in 3500 BCE, in Mesopotamia, Egypt, China, and even in the South Pacific, people understood there were significant forces of nature and wanted at least to use them to their advantage. Diverting water and controlling it with valves could irrigate the crops and grow a hungry population; sailing across water could lead to places with new goods or resources. Fire was the life-giver to humans, known early on to the oldest of hominids, and staying with us through our evolving species. Shaping the earth into houses or bowls for food was part of daily life. But the air they breathed–could they control it? The wind brought storms that wrecked the crops and disturbed the cattle–could they harness it?

V is for Valve

Indoor plumbing doesn’t get enough credit. We take it for granted, but one night spent camping is always enough for me to write fan letters to my en suite bathroom at home. In fact, plumbing as a whole doesn’t get enough credit. Prehistorians love to wax lyrical about the plow or cave paintings or Platonic ideals. They should be talking about irrigation. After all, find a sizeable population in history, and you’ll probably find a valve.

The Romans kind of cornered the historical air time on valves since they were the gold standard (Bronze standard? it’s the Bronze Age…) for plumbing as well as central heating. Numerous articles cover this in Valve magazine, and yes, there’s a magazine dedicated to valves. However, while we should give the Romans their due, the Egyptians were the first to use valves in irrigation, the Indus Valley builders of the largest public baths, the Mesopotamians creators of one fabulous desert garden after another, and the Incans masters of harnessing gravity to create waterfalls and canals.

Harnessing the power of water was one of humanity’s first ways of controlling their environment. The valve was an integral part of the story, such a simple little thing but very powerful. The best inventions are. Let’s consider:

  1. What is a valve?
  2. When and where were valves first introduced in ancient civilizations?
  3. What does the creation of the valve and the control of water imply about human thinking?

U is for Umbrella

Combine the histories and myths of Daedalus, Da Vinci, Archimedes, and St. Joseph into a single person. Now give that guy a wife, one who has learned some practical science from her husband. She invents the umbrella. Sort of.

The umbrella, a device used as a sun shade or rain cover, dates back to almost 3000 BCE. Since the ancient cultures that we know most cluster around the Mediterranean, the primary use of umbrella-like instruments was as fans or canopies to protect mainly the royals, and later the wealthy and aristocratic. Thus, the umbrella in the most ancient sense, was a status symbol.

But the other form of umbrella we modern people know is the collapsible kind–that is, those of us who experience rain in the north (or extreme south). Collapsible umbrellas, invented somewhere between 600 BCE and 50 CE in China, were also more symbolic than functional, at least according to art left behind. The Chinese led the world in innovative designs of the umbrella. Europeans came to know the designs; they just didn’t use them. At least, not until umbrellas were re-invented as a status symbol, eventually to make their way into popular and practical use by schmoes like you and me.

In focusing on the history of the umbrella in ancient times, let’s consider:

  1. What were umbrellas for?
  2. Where and when were umbrellas used in ancient history?
  3. What does the invention and innovation of the umbrella signify?
