     Bread is called the staff of life. When I was a kid, I thought of a staff as made of wood. A staff made of bread made no sense. That was before I understood metaphors of function: just as a staff supports a man, so bread supports life.
But in fact through most of human existence, there was no bread. The earliest archeological evidence for bread of a sort is about 30,000 years old. By that time homo sapiens had existed for at least 200,000 years. That bread was a cooked or semi-roasted porridge made of grains; I don’t think anyone nowadays would recognise it as bread. Flatbread baked on hot stones or a griddle are the modern equivalent. The archeology shows that these first bread makers relied on hunting and gathering for most of their food. Cereal grains were one among several types of seeds gathered for food. It took several thousand years to develop cultivation of grains; perhaps someone noticed that spilled grain would provide a crop the following year, and decided to experiment. However it began, that invention or discovery began the constantly accelerating development of technology that has made our species the dominant life form on this planet.
     Bread as staple food and agriculture go together, in fact agriculture makes no sense without bread. The earliest agricultural settlements were villages, some fortified, some not, surrounded by fields and pastures. The last users of stone tools built them about 10,000 years ago. When metallurgy was invented around 3500BCE, that technology developed swiftly, and within a few hundred years we find cities dominating the farming villages in their vicinity. These complex polities require writing, an armed force, and centrally administered law to survive.
     I think it’s no accident that the invention of bread and the earliest forms of writing, mnemonic symbols, are nearly contemporary. These symbols were used to help the reader recall everything from lists of trade goods to signs of future events to myths, those stories in which the sacred and secular histories of the tribe were mingled. Surprisingly quickly, these early mnemonic systems developed into scripts.
     Bread as staple requires agriculture, which requires a hierarchical social structure to ensure that the backbreaking (and boring) work of plowing, seeding, and harvest was done. A hierarchical society needs an agreed body of rules and customs. Law, in other words, enforced as much by common beliefs as by physical force. Customs, religious and otherwise, express the common understanding of how the world does and should work. Written law codifies those beliefs; the law describes what is to be done and what is not to be done. Writing is also handy for keeping accounts, so much so that writing numbers may have predated writing words.
     Bread is not only the staff of life, it’s the driver of those changes in human society that we are pleased to label progress.
