2 The science of archaeology studies the For those times that we term prehistoric, remains of the past and seeks answers to in which the Minoan and the Mycenaean mankind s fundamental questions about civilisation flourished, archaeological history. These may research is our only source be given by the of information on past people themselves human activities. who lived before Archaeologists seek us through their answers in the great writings. However, book of the land and sea, there were times where thousands of before writing was secrets are hidden: discovered or eras submersed cities, in which people used scripts that we are still The pioneers in archaeology sunken ships, ports swallowed by the salty not able to read, such as the water of the sea, hills and valleys hidden Minoan script or Linear A. under the earth through the passage of time. 2

3 Excavating the past When I was young I was impressed by the ancient world. When people asked me what I wanted to become, I always answered: An Archaeologist! I have dreamt of discovering something important all my life. This is the work of the archaeologist: to look for traces of the past by digging up the earth/land, searching in caves, banks of rivers and shores of lakes, even the bottom of the sea. There can be ancient finds everywhere, under our feet Archaeologists try to find them and study them. Their work requires collaboration with other scientists and specialists (geologists, architects, conservators, photographers, draughtsmen, etc.). From the beginning archaeology was related to adventure. Some may even consider the work of an archaeologist to be frightening and dangerous. It is not simply a profession! It is an adventure! 3

4 For many, Heinrich Schliemann, who was self taught, is the model archaeologist. We see in him the lonely hero who travels to far away places seeking knowledge. This is a model found in many films and books on archaeology. Schliemann believed that he could prove that the places mentioned in Homer s epics really existed and managed to do so. History will remember him as the person who excavated the legendary Mycenae, Troy, Tiryns and Orchomenos. His life has been an inspiration to many archaeologists. We have to remember though that Schliemann was a man of his times, an era when archaeology was making its maiden voyage as a science. What is important is that every archaeological discovery has a dose of mystery. Even the expressions used by archaeologists, such as discovery and solution remind us of detective stories. That is why the world frequently sees archaeologists as detectives that solve a mystery with the use of their powers of deduction and a lot of studying. Let us see what will we discover this time? 4

5 How do archaeologists find ancient objects? Every year, especially in the summer, there are a lot of excavations in many places around the world Most excavations are for the purpose of preserving ancient remains and handing over a space for private use or for the construction of major public works. These are called rescue excavations. They help preserve valuable information about the historical past of a land without obstructing modern development. Some times, however, antiquities can be found completely by chance In the spring of 1863, a mule driver who was transporting sand from the small hill of Agia Triada close to Piraeus street in Athens, made a major discovery. As he was shovelling sand onto the cart, his shovel struck a piece of marble. He notified the owner of the land about his find and immediately he came and dug - bringing to light a funerary stele inscribed with the words Α[GATHON A]GATHOCLEOUS. This led to the excavations that revealed Kerameikos, the greatest cemetery of Ancient Athens. So random finds can be uncovered when a farmer tills his land, an engineer digs to lay the foundation for a building or works are carried out to construct roads and other major projects. Remember the works for the construction of the Athens metro. When the tunnel boring machine (affectionately called the metro mouse) started digging, it discovered the city beneath the city, i.e. Ancient and Byzantine Athens that had been buried under the modern city. Archaeologist waited impatiently to see what would be revealed. Now that work has begun on the Thessaloniki metro, all eyes are on Thessaloniki! 5

6 Systematic Research In most cases archaeologists find antiquities after systematic research and study. They study ancient writers, such as Thucydides and Pausanias, who describe their own world and they try to match it to the present day. In this manner they can locate the position of an ancient city, an ancient port or temple. Often these places have kept their ancient name, either with or without changes to it. This fact alone is a valuable piece of information a starting point for research. The traveller Pausanias wrote about Eastern Attica: At some distance from Marathon is Brauron, where according to the legend, Iphigenia, the daughter of Agamemnon, landed with the image of Artemis when she fled from the Tauri (Pausanias, Description of Greece, Attica, chapter 33.1, Translation W.H.S Jones). Braona, where the temple of Artemis was found and which was known from references by ancient writers, is an area which kept alive the memory of its slightly altered ancient name through the centuries. 6

7 Excavations step by step First Step: Surface survey If there are ancient walls buried below the surface in a field of wheat, look at what happens to the crop Equipped with notebooks, maps and cameras, archaeologists survey the area where indications of antiquities exist. A pile of hewn stones at the edge of a field, scattered pottery sherds (ostraka) in the earth, marble columns and column capitals built into walls of old churches are some of the many signs that testify to the existence of antiquities. However, some times, when antiquities are completely buried below the surface of the earth, they send out messages to archaeologists revealing their position! Where there is only soil plant, roots absorb the water that they need to grow properly. However, where ancient walls exist, the roots do not absorb the same amount of moisture and the plants don t grow as much or turn yellow. Drawing: Dimitris Koukoulas, Architect Engineer 7

8 Technology at the service of archaeological surveys People working in an excavation Looking at the world from above, archaeologists can identify changes in the colour or the relief of the land. These changes cannot be distinguished from the ground, however, they frequently indicate that there are buried ruins below. Another modern method for finding archaeological remains underground is geophysical investigation, in which the electromagnetic field of an area is recorded by special devices, magnetometers. The team in charge of an excavation consists of various specialties. Besides archaeologists, there are also architects, photographers, draughtsmen, conservators, geologists, anthropologists and specialised workmen. Shovels, picks and hoes, trowels, wheel barrows, brushes and paintbrushes, string and stakes are the main tools of an excavation. In addition, archaeologists use some very thin instruments, similar to those used by dentists. 8

9 Second Step The excavation commences The excavation commences with a trial trench, in which a small part of the area selected by the archaeologists is investigated. If the results are encouraging archaeologists continue with the excavation. They first clean up the area carefully. Then they create 5x5m squares using stakes and string. They separate the squares with numbers on the one side and letters on the other. Each square (box grid) is given a name, e.g. Α1, Β3 etc, so as to be able to identify where each item was found.

10 And now the real work begins Every square is excavated separately. Archaeologists leave a strip of land with a diameter of 1 meter between the squares as a reference called balk. Workmen with their wheelbarrows circulate on the passageways formed by these strips of land in order to remove soil. The stakes that separate the squares are placed there also. Balks give archaeologists a view of the stratigraphy of each square. Stratigraphy is the study of consecutive layers of earth. Those layers were created through the centuries from the activity of either people or nature. The archaeologist observes the different layers of colour (e.g. reddish, brown, blackbrown) and the texture of the soil (soil with pebbles, sand, clayish soil, etc.). Each layer corresponds to a different period of inhabitation in this area and maybe a different era..

11 Investigating the squares When the time for the excavation arrives the workmen remove carefully the soil and the archaeologists notice any changes in the soil, its texture or colour. The archaeologist notes everything down in the excavation log and continuously takes photos, making a record of all stages of the dig. Workmen throw the soil into baskets and remove it with their wheelbarrow. Frequently archaeologists sift the soil to make certain that they don t miss small objects, such as the bones of small animals, seeds, beads or jewellery. Archaeologists using a brush to clean the surface to be able to see what is buried below. 11

12 At last we have a find! The happiest moment for the entire team! Archaeologists don t take an object out of the soil as soon as they begin to see it. First, they investigate the layer in which it was found, they photograph it and then carefully remove the soil around it with a trowel or small knife, continuously cleaning it with a brush. Slowly other finds come to light. The same procedure is repeated until all objects are taken out of the soil. Once the objects have been photographed and drawn they are removed from the pit. Depending on their size, they are placed in plastic bags or cardboard boxes together with their tags, which record the exact location they were found in.

13 Third step From the excavation to the laboratory Once the day at the excavation site ends, all the moveable finds, placed according to their size in cardboard boxes and plastic bags are taken to the laboratory. There another team starts working on them, cleaning them and recording them. Conservators clean the finds with water and soft brushes. Then they lay them out on benches to dry well. Now the time to record the finds has come: each object, even the smallest part of a vase, has to be given an identity. That is a number that the archaeologist notes on the object at some not so noticeable point. Then they apply a transparent varnish over the number so that it does not get erased. Then the object can be handed over to the conservator to put together its pieces and to conserve it. After this stage the object is returned to the archaeologists to be studied.

14 Fourth step Studying the finds...and study the space ΑValuable information can be drawn even from the smallest of finds. For example by performing the appropriate chemical analyses the archaeologist can date the layer in which it was found or learn something about the use of the area. The archaeologist notes down all observations and conclusions in the excavation log. Any finds deemed important are given to the draughtsman and photographer. Then they are placed in an orderly manner in the excavation store room. Certain of these the most important and interesting end up in the display cases of museums. The rest remain in storage areas. Besides studying the finds, archaeologists must also study excavated space combining the information with that obtained from the finds. At the same time architects make drawings of the buildings found and conservators intervene to secure the walls, wherever necessary. That is why it is very important to study objects in the exact place they were found. Individual objects that are taken away from the point in which they were initially found such as those from illicit digs- do not speak to us. Often we don t know to whom they belonged, to what other archaeological finds they are connected, and we find it hard to date them. 14

15 Underwater archaeology Antiquities are not only hidden in the earth, but also in sea, lakes and even river beds. In these cases the investigations are carried out with archaeologists divers that work in underwater archaeology. The conditions of the excavations are different from those outlined above. Low visibility in the water; a muddy sea bottom; divers who have to work without standing on solid ground; the limited time under water make underwater archaeology very difficult, but also very attractive. The method of the excavation and the tools used differ greatly from those used on land. For example instead of the shovels, wheelbarrows, buckets and trowels used by archaeologists on land to remove the soil, below water divers-archaeologists use electrical vacuums devices that operate underwater.

16 From the moment that they find an object they work with bare hands to get it free of the sand. Using special cameras, pencils and slates they take notes, just like in other excavations. If you want my opinion, archaeology is just about as adventurous as these books I have to read!* The work of the archaeologist What is the image that the world has of the archaeologist and his work? Archaeologists love adventure and mysteries; make important discoveries about mankin; and protect our cultural heritage. Often, we see in archaeologists the old ideals of explorers, those persons who love the past, adventure and glory. However, is it so? The day to day life of archaeologist differs greatly from this ideal image. *C. Holtorf, Archaeology is a Brand! The meaning of Archaeology in Contemporary popular culture, Oxford

17 Archaeologists spend most of their time behind a desk drafting public documents, opinions, studies for showcasing archaeological sites and museums, studies for re-exhibiting museums or involved in cases related to private individuals. Most people only know one part of the archaeologist s work: excavations. However, most time is devoted to studying and drafting research reports. In recent years archaeologist have gained ground and are seen as scientists that care for the cultural heritage, helping to preserve it for the future generations and preserving it from illicit digs and smuggling. That is why the following is true for archaeologists... Now that I have read all this, excavations have lost their appeal! It is not an adventure, it is a job But this job makes you dream of adventures 17
