The Digital Atlas of Innovations: A Research Program on Innovations in Prehistory and Antiquity
The authors discuss the simultaneous appearance of technological innovations in three key technologies (metallurgy, wheeled vehicles, weighing systems) in the second half of the 4th millennium. This is done from a source-critical perspective because the innovations are discussed with the help of dynamic maps from the Topoi project Digital Atlas of Innovations. Besides indications of diffusion gradients influenced by special research conditions, exceptional waves of innovation can be detected for all three technologies in the discussed period. These waves of innovation cannot, however, be generalized but have to be understood on the basis of the respective technology traditions and lines of development specific to local areas. Monocentric diffusion theories can be clearly disproven, local technology developments and their converging in certain centrally situated regions have to be assumed instead. Similarly, the transfer of objects and their châine opératoire can only be detected rather infrequently, while the adaptation to local socio-economic and environmental factors can be demonstrated.

1 Introduction
Since the 19th century the history of technology started with the inventions in the Early States in Egypt and Mesopotamia. All inventions were made in the centres and then spread over the world into the peripheries. This kind of diffusionism was unsettled by the radiocarbon revolution which pushed back some innovations in time. Metallurgy was invented long before the ancient city states and the first evidences for wheel and wagon were found in a wide are from the Atlantic to the Persian Gulf.
Beside radiocarbon revolution the end of East-West bloc confrontation made new research possible understanding the interdependencies between Europe, Western and Central Asia and the Far East in the Holocene.
Under a layer of outdated assumptions it is possible to expose new empirical evidences for the innovations in toolmaking and craſtsmanship but also ideologies which in many cases coined the live and dead of people until the 18th and 19th century. This has to be done in the perspective of a global history of knowledge to which archaeology can make a major contribution. The long durée and the global perspective unfold an explanatory power in the history of knowledge. It is one history of knowledge and all kinds of knowledge are of equal value. Now, the emergence, the transfer and transformation of knowledge can be traced over thousend of generations by archaeology.

2 The Digital Atlas of Innovations as a tool. Possible applications
Everytime when the world was measured anew, new maps were required. The Digital Atlas of Innovations is a new tool, an interactive, interoperable map connected to a continuously growing find database. For a long time, archaeology has been collecting the material remains of many innovations, from the first use of fire in the Paleolithic to the first use of pottery in the Neolithic to the invention of the screw in antiquity. Admittedly, the mapping of, in each case, the earliest evidence of great and small innovations already allows us to locate the technologies in the world. However, these maps oſten have only illustrative character. The Digital Atlas of Innovations, on the other hand, is a dynamic tool that makes developments and relationships identifiable. We will, of course, never find out where the wheel was invented. Therefore, the Digital Atlas of Innovations examines the earliest evidence of innovations over a longer period. That is the first 2000 years in the case of wheeled vehicles! The innovations are embedded into an examination of the long duration (longue durée). It is the strength of prehistoric archaeology not only to look at such long periods of time on the basis of physical age determination, but also to be able to examine them precisely for short-lived booms.
An atlas consists of a wide range of maps. The scale of the maps is determined by the manageability when used. A world atlas offers an overview of the countries of the earth; in order to capture the geographical details of individual countries, on the other hand, one needs different atlases. The Digital Atlas of Innovations is not restricted by such limitations. It is a dynamic tool that makes it possible to change the scale of time and space and to continue creating new maps. With the aid of a timeline, all pieces of evidence for innovations can be represented in decades, centuries or millennia. The Digital Atlas of Innovations allows also to distinguish periods of increased technological innovations from those times in which no or very few changes can be recognized (Fig. 1). In the same way, innovative regions and innovation-hostile regions can be identified. It will be possible to determine which bodies of knowledge were, aſter all, available in individual regions or could have been available.
The Digital Atlas integrates the archaeological sources on several different levels and, in doing so, is able to represent different steps of a production chain. Therefore, it is not only possible to map the earliest evidence for a certain innovation on the basis of finds, but also to generate maps for different detailed solutions based on technological properties. The earliest use of silver can be represented on the basis of finished products, the cupellation on the basis of byproducts.
By trade or given as presents, objects can become widely distributed without the associated knowledge of their production being spread as well. The Digital Atlas of Innovations is, however, able to prove the distribution of formulas, in other words, hard technological knowledge, for example based on the characteristics of copper alloys (see below). It is also suited to represent ritual practices like sacrifices, for instance, on the basis of their remains in time and space. At the same time, a source-critical basis for the representation and discussion of the emergence and spread of technological knowledge is created in doing so. There is always the question in which archaeological contexts objects have been passed down (e.g. as a sacrifice) and under which conditions they have survived (e.g. wood in moors and deserts). This is also important regarding those artifacts whose material can be re-used regularly, like copper and silver: mostly those artifacts have usually survived that were consciously withdrawn from the recycling loop by depositing them in graves or hoards. Therefore, it is a given that the find contexts can be linked to the objects in the mappings.
It has to be stressed that the dynamization of the archaeological ‘distribution map’ allows us to recognize new relationships in time and space. The existing distribution maps show stages of innovations, defined by the respective scholar for different reasons. Oſten,

these stages are (arbitrarily) assigned time marks. The Digital Atlas of Innovations, however, aims at reading the rhythms of development and periodizations in the maps. Therefore, new questions can be generated from the maps. The maps in the Atlas of Innovations are not the illustration of a statement, but a heuristic device on the basis of which new questions can be asked. They constitute the beginning of a line of thought. The map itself becomes an essential device to direct logically consistent lines of thought.1
3 Innovation and technology as a social phenomenon
Innovations are new and useful things.2 As a result, earlier research oſten explained their spread with the help of a functionality paradigm. According to A. Toynbee, technologies are developed in order to solve challenges and problems in interacting with the environment.3 The right amount of problems, i.e. a certain environment, finally leads to the kind of technological progress that was followed by the first states. U. Eco, however, has challenged this notion of innovation by critically considering the sources, asking whether

innovations that have been interpreted as creative quantum leaps could not just reflect the absence of other serially produced counterparts. Furthermore, his and newer considerations show that the variation necessary for innovation is oſten accidental and emerges from the creative handling of known technologies.4 According to this, an innovation is a creatively and newly arranged selection of known features which will be accepted if it fits into the society’s repertoire of symbols.
Technological innovations already were an integral part of different primates’ cultures, i.e. they are not an exclusive characteristic of human beings.5 Especially artifacts, in other words, mechanizing innovations, can be archaeologically recorded, while innovations on other levels have to be inferred via analogies. The ability to implement almost continually new technologies in a social system is a characteristic of our culture – and has been since its earliest beginnings. At 3.6 million years, the earliest stone tools known at the moment are even older than the species Homo,6 and this circumstance could be read to the effect that the use of stone tools by Australopithecus was an important factor for the human evolution. Thus, technology made humankind.
Technology and society structure each other in a network of relationships on different levels and over long periods of time: For such a process, however, technologies also have to be compatible with the social system in which they are intended to work.7 Since existing technologies can be degraded by the emergence of innovations, an innovation does not suddenly lead to an improvement of living conditions.8 For this reason, too purposeful an understanding of innovation is only useful to a limited extent. For example, innovations can be due to the marking of cultural characteristics and the targeted search for cause-effect principles.9 Even if the invention of new technologies is oſten associated with individuals, their development is far more complicated. Technological innovations draw on elements of known technologies and improve these or combine long-known aspects in a new way.10
Innovations spread or are rejected precisely because they are socially relevant. This happens, for example, when people that are considered exemplary use them or when the non-use as a deviation from given standards leads to social sanctions.11 As a consequence, the imitated group can see themselves forced to define new standards which produces further innovations.12 In this way, the consumption of innovations can develop its own dynamics that is fed by the pursuit of social distinction.13 The taking up of an innovation is, however, also a risk since the desired distinction is not guaranteed, and people without access to the technology can subsequently lose their status. Moreover, an open society that is prepared to allow innovations and understand their social value is a basic condition. Therefore, innovations are particularly promoted by social fringe groups that risk a loss of status more easily.
The work of E. M. Rogers, who believed to have identified five aspects that decide over the acceptance of innovations, is instrumental for researching innovations in modern times.14 When an innovation convinces, the adaptation process begins in which the innovation is used by an increasingly larger group – this is diffusion and can be graphically

represented as a sigmoid curve in a coordinate system with the users on the y-axis and time on the x-axis. Since the archaeological sources record innovations only when they have already been adopted, it is almost impossible to document the invention and the early stages of the innovation archaeologically. During this diffusion, the innovation has to be communicated; this can usually be tracked well on the basis of the archaeological sources.
Although a number of modern consideration can also be applied to prehistoric and ancient societies, there are specific features that are hardly taken into account by modern innovation research. For example, the mastery of the whole production chain, including the sourcing of raw materials, their preparation and processing, is necessary for a permanent adoption of innovations. In the case of wheel and wagon, the general availability of wood and the mastery of woodworking is certainly a reason for the rapid and far-reaching spread. In contrast, the production of complicated metal tools obviously remained limited to a few regional centers.
3.1 Archaeology and technology
Prehistoric societies invest a significant part of their time in the modification of their artifacts. Besides the obvious improvement of tools, there can be a number of reasons for this. In an ongoing process, old artifacts are abandoned and new ones introduced. It is thanks to this fact that C. J. Thomsen’s15 division of prehistory into a Lithic, Bronze and Iron Age is, in principle, still valid today. W. F. Ogburn has postulated the temporal primacy of the technological development over the social development, coining the term “cultural lag”.16 According to this theory, technology develops more quickly than society, so society continually has to adjust to the conditions caused by the new technologies. V. G. Childe deduced the indeed great importance of technology from archaeological finds, but also showed how certain forms of society enable the generating of new technologies in the first place.17 With this, he overcame, at least for prehistoric times, Ogburn’s postulate.18
Only recently, the necessity of certain technological and social conditions has been increasingly pointed out in archaeology and their existence emphasized as vital for the spread and acceptance of innovations.19 The history of sciences and technologies as a field of work has existed for some time, however.20 An archaeology of innovations is not a matter of applying concepts worked out on the basis of other data to the finds, but to review these concepts with the aid of archaeological sources and to develop archaeological innovation research. Archaeological and historical sources offer, despite all their specific shortcomings, good conditions to examine the interplay of technology and society over longer periods of time. Due to their temporal depth, they are able to track the individual elements of which a technology is composed and they grant an insight into long formation processes of technology, and the willingness of societies to accept innovations and its consequences.21 The understanding of the development, introduction and spread of technologies, and of the resulting social processes in prehistoric and ancient times is certainly in its very early stages and remains a research field that still has to be established, but possesses areas of contact with the history of technology of antiquity,22 the Middle

Ages23 and modern times.24 The Digital Atlas of Innovations can make not only prehistoric and ancient innovations visible, but also those from later periods.
The social implementation of technologies, for example, is of vital importance in the spread of innovations,25 while continuous innovations can permanently damage a society. Moreover, the adaptation and diffusion of innovation requires consent about its usefulness. Such consent can only be communicated, however, if those innovations which are still in the adaptation stage do not disturb the social system too much. Therefore, one would have to consider whether a long-term interchange exists in successful societies between periods in which innovations emerge in batches and periods in which the return to tradition helps a group stabilize the social reproduction again.
The ability of innovation is a feature of all human societies. Some societies succeed, however, in developing innovative technologies that result in dramatic changes. In the long term, innovations possibly bring about a measurable improvement of living conditions (lower child mortality, increase in life expectancy). In the short term, however, dramatic worsening is possible, too,26 since technologies are interwoven with social infrastructure in many and varied ways. This network is disturbed by innovations so that a society which is continually changing is soon confronted with social problems: Because missionaries distributed steel axes among adolescents, women and children of the Australian Yir Yoront in the early 20th century, the traditional stone adzes lost their function, not only as a tool, but also in religious contexts and as a status indicator of mature men. With this, the power basis of those groups controlling the distribution of stone adzes immediately collapsed, and steel axes became necessary to assert one’s social position. As a consequence, men forced their wives into prostitution in order to get steel axes, and new exchange systems developed revolving around steel axes.27 The steel axe as part of another world did not, however, colonize the Yir Yoront because more trees could be cut down or this could be done faster, but because how their society valued axes.
3.2 Innovation cycles
Periods in which innovations induce further innovations and permanently change a society have been called “hot” periods by various archaeologists28 following C. Lévi-Strauss29 as opposed to “cold” periods. In the “cold” periods, a society attaches great importance to constancy and stability and is, therefore, less innovative. This insistence on traditions can indeed be advantageous under certain circumstances.30 If this interpretation is true, important innovations appear bundled together and are distributed as a ‘package.’ This, in turn, could mean that the technological differences visible today between archaeologically surviving societies can be traced back to the conditions for communication. Thus, groups with intensive long-distance connections would have had an increased chance of gaining knowledge of innovation packages. Archaeology itself seemed to deliver the evidence since the diffusion of innovations on the Eurasian continent from east to west is considerably less hindered by different climate zones and mountain ranges than is the case between South and North America or throughout Africa.31 Beyond the Ne-

olithic transition, however, this concept reaches its methodological limits. For example, the spread neither of wheeled vehicles nor of copper metallurgy can be explained only by the conditions of the natural environment.32
4 Wheel and wagon – facets of an innovation
There is no need, according to general conviction, to reinvent the wheel. It seems so fundamental that a society without the wheel is difficult to imagine. So far, 2421 pieces of evidence of pre- and protohistoric wheels have been cataloged in our database (Fig. 2).33 The majority of finds has been classified as “real-life objects”, meaning they are parts of actually used wagons, while illustrations and models of wagons only account for about one third of the stock of finds. These finds come, in roughly equal shares, from settlements, graves and the art trade; some wagons have also survived as petroglyphs (rock art) and in hoards. The definition of the time interval from 4000 to 2000 BC makes it clear that the early wagons remain restricted to a triangle between central Europe, India and Siberia (Fig. 3). It takes about 1500 years until the wagon can also be traced in other regions. Looking only at the early wagons, it is apparent, too, that almost half of them are miniature wagons (or parts of them).
