Before the Mycenaeans there were the Minoans, who built a wide-ranging empire based on their capital of Knossos on the island of Crete. They were a seafaring people, confident enough in their navy that their cities were unfortified. At the height of their power the Mycenaeans entered mainland Greece from the northwest, conquering the previous inhabitants and settling in the Peloponnese, the southern part which a thousand years later would be the land of the Spartans.
Minoan civilization eventually collapsed. Around 1600 B.C. A massive volcano exploded on Thera (present day Santorini) which caused widespread destruction across the eastern Mediterranean. The Minoans rebuilt but never fully recovered, and an earthquake around 1450 B.C. spelled the end for them as a unified power. The Mycenaeans took advantage of their weakened state and invaded, setting up a second power base for their civilization.
Three hundred years later the Mycenaeans themselves were destroyed, probably by the invaders known as the Sea Peoples, who laid waste to ancient civilizations across the region, including in Anatolia, Syria, Phoenicia, Canaan, and Cyprus. The Egyptians under Ramses II managed to turn them back but at such a high cost that it took centuries to recover. After the collapse of the Mycenaeans Greece entered what are called the Dark Ages from 1100-750 B.C., when the cities were laid waste, art and science vanished, and stone palaces were replaced by mud and wattle shacks.
The Minoans had a written language, called Linear A, which to this day has resisted translation. After their conquest by the Mycenaeans it was replaced by Linear B, which was finally deciphered by Michael Ventris in 1953 and found to be an early form of Greek. Thousands of tablets of Linear B have been recovered from various Myceneaean sites, and have yielded a great deal of information about the civilization.
The first writing is attested around 3500 B.C., in the form of Sumerian pictographs, which would later evolve into cuneiform, which would become the standard for recording dozens of languages across Anatolia, Syria, Mesopotamia, and Iran for three thousand years. The very last cuneiform tablets are from Egypt in the first decades A.D. Writing came into existence for very mundane reasons: to record items and quantities. These were useful for merchants, but especially so for rulers, because as leaders expanded their span of control they quickly found they needed a system for keeping track of who had paid their taxes and where things were stored.
Eventually cuneiform would also become a literary form of expression, recording speeches, prayers, rituals, and even the first epic, the story of Gilgamesh. If the Mycenaeans made similar use of Linear B, it has vanished, because what remains are only administrative records, and only for those on the eve of their civilization’s destruction.
The evidence suggests that the Mycenaeans kept their current-year records on clay tablets, as a quick way of keeping track of day to day accounts, and at the end of the year summarized the results on parchment and destroyed or recycled the clay. Most of the tablets were in the form of flattened cigar-shapes, which would result from rolling up clay and then pressing it flat. Records were stored in a central repository, and everything for a single type of transaction was stored in reed baskets, with a clay marker on front explaining what was inside. The baskets were then placed on wooden shelves in a storeroom. Scholars know all this because they have found markers whose reverse sides show the impressions of the baskets onto which they were pressed. When the end came for Mycenaea it came quickly. The palace was looted and burned, and the heat from the burning shelves and baskets fired the clay tablets, which were never meant to be permanent, so that they can still be read three thousand years later. As the shelves collapsed, however, tablets were broken and scattered, and much of the work of scholars is to fit fragments back together and read the contents.
Sometimes the scholars get lucky, and can trace words back to Homeric or Classical Greek. However, as with all invasions, the invaders absorbed much of the language of the original inhabitants, and the meaning of many of those words were lost during the Dark Ages. Some can be guessed at from context, but many of their meanings will never be known.
One of the largest groups of tablets is from Pylos, a kingdom in what is now southwest Greece, the domain of Homer’s Nestor. According to its Wikipedia article, it covered approximately 2000 square kilometers, and had at least 50,000 people, and possibly as many as 80,000-120,000. Managing that many people and their crops, livestock, and other resources was no easy task, and while the tablets record only dry administrative details, they shed light on the life of the kingdom. The scribes recorded taxes due and received, cloth and metal sent to artisans, food rations delivered, and offerings to the gods, some of whom can be traced to the Classical pantheon, and some who were local and vanished with the fall of the city.
There are also some tablets which seem to record the military preparations as the last days approached, accounting for things such as how many chariots were in serviceable condition, and who was issued weapons or armor. The invasion appears to have come from the sea, and overwhelmed the defenders, causing the population to flee the city and into the mountains. The fact that very few bodies were found in the remains of the looted and burned palace suggests the people had fled beforehand.
Three thousand years was a long time ago, so it is fascinating that we can re-create so much about this ancient society. It was highly organized and efficiently administered, complete with records of partial payments and rebates offered on taxes. Considering the administratively disorganized city that I live in today, I’m not sure our computers and automated systems have made any real improvements. This book was published in 1976, which is itself ancient by modern standards, and much of what it says has probably been updated or contradicted. Still, it is a useful introduction, especially in the way the scholars use deduction and inference to make up for having only partial information. If, for instance, they know A and B, they can infer C and from that make an educated guess at D. The book is not a general history of the Mycenaeans, being focused solely on what can be learned from the surviving tablets, but it tells an interesting story, both of those ancient times and of the modern experts who try to restore what they can from the fragments that have survived the ravages of time.
