Identifying Selement Paerns and Territories 1 Jens Andresen – Rasmus Birch Iversen – Peter Jensen On the War-Path: Terrestrial Military Organisation in Prehistoric Denmark Abstract: Through the use of vector-based GIS-technology, quantitative methods, historical and traditional archaeological sources, the authors point to a close relation between the location of Iron and Viking Age finds, sites, and structures related to warfare and the Danish highway network as it is known from the late eighteenth and early nineteenth centuries. It is argued, that this relationship reflects a system of military organisation embedded in the selement structure and that its roots can be traced as far back as the early first century BC. Introduction For a long time the concept of war has been under- stated in Danish archaeology. During the 1970s and 1980s, the focus was on selement archaeology, ru- ral economy, trade, and social issues. Mildly exag- gerated, one could say that society was described as an essentially peaceful cosy Shire inhabited by pipe- smoking, garden tending hobbits, living in oblivion of the chaotic world outside and only occasionally harassed by external threats. Only in recent years we have witnessed warfare discussed as a prime mover in the formative process of the prehistoric society of Denmark (Otto / Thrane / Vandkilde 2006). This trend is also visible in the study of Iron Age and Vi- king societies, which increasingly are perceived as martial societies, i.e. societies in which preparation for war and conflict was imbedded in the social or- ganisation, or even that social organisation simply was military organisation (Hedenstierna-Jonson 2006). Admiedly, some insights in the structure of pre- historic armies have been uncovered (Ilkjær 1990; Müller-Wille 1977; Näsman 1991; Pedersen 2004). However, aempts to produce a quantitive synthe- sis of these results and results from the study of the apparently peaceful daily life in the rural sele- ments are very scarce (Ringtved 1999). Additionally, the study of maritime aspects of military organi- sation in Northern Europe has achieved many in- teresting conclusions on maritime warfare (Crum- lin-Pedersen 1991; Graham-Campbell et al. 2001; Jørgensen 2002; Skoglund 2002; Varenius 1998). At the same time however, the maritime focus has defined a limited scientific horizon per se, focusing on ships, harbours and coastal zones. In this paper, we will focus on non-maritime (terrestrial) aspects only. A central aspect in the study of war and conflict inland are graves containing weapons and/or riding gear. In previous studies, the spatial distribution has been illustrated by dot-maps. As the background in- formation of the dots, natural – not cultural – pa- rameters, such as coastline, height above sea-level, lakes, and water-drainage were chosen. One of the benefits of GIS-technology is the ease with by which all sorts of geographical information can be overlaid. Compared with paper-based information, GIS-technology offers superior features for spatial exploratory data analysis. The conventional paper- based information management may be the primary reason why nobody seems to have noticed that the distribution of graves of horsemen and warriors in the Iron Age and Viking period strongly associate with the network of major roads known from the end of the 18 th century. The aim of this paper is to confirm the observed correlation statistically and to discuss inferences concerning the military organisa- tion in prehistoric Denmark. The Terrestrial Infrastructure of the Martial Society From the earliest wrien sources describing the Germanic tribes, the sources unanimously tell us of societies with an unusually martial ideology. This is clear from the accounts of Caesar, Tacitus, Am- mianus Marcellinus or Vegetius, who for instance states: Even today the barbarians think this art [of war] alone deserves their aention; they are sure that everything

The Terrestrial Infrastructure of the Martial Society

From the earliest written sources describing theGermanictribes,thesourcesunanimouslytellusofsocietieswith an unusuallymartial ideology. Thisis clear from the accounts ofCaesar, Tacitus,Am-mianusMarcellinus orVegetius,who for instancestates:

Even today the barbarians think this art [of war] alone deserves their attention; they are sure that everything

else either depends on this art or can be obtained by them through it. (Vegetius: Epitoma ReiMilitaris III; 10.FromMilner1993,86)The accounts of continuous Viking assaults on

Anglo-Saxon England and the Frankish realm isprobably only a continuation of this ideology ofwar.InthefollowingwewillapproachthequestionofthecomplexityofIronAgemilitaryorganisationinDenmarkinalongtimeperspective.Thisisdonein a statistical, logistic and landscape perspective,whichwill reveal fragmentsofacomplexmilitaryorganisationofsociety.

The Relative Permanence of Road Networks

Armiesofthesizeweseereflectedinthewar-bootycollectionsoftheRomanIronAgeandindeedintheVikingAge, cannot have operatedwithout inlandroads.Althoughwe candemonstrate roads in thearchaeological record – ranging from gravel-filledwheel tracks to stone and plank built roads – theevidenceismostoftenfromrivercrossingsorotherprotectedlocations.Theyaresparseandtheyarenot

There aregoodreasonsforthisbeingso,culturallyaswellasnaturally.Aculturalreasonisthatroadslinksettledareas: roads and settlements mutually determinetheirpositioninthelandscape.Anaturalreasonisthatroadsystemsrelatetothegeomorphologyofagivenarea,whichinahumanperspectiveisaverystatic property of the landscape.

The produc-tionprocess tookplace from1762 to1820.Theuseof this source in amodernGIS-systemwasmadepossible by one of the authors of this paper, JensAndresen. In1997hedevelopedamethod togeo-reference these and other historical maps. He re-questedacompletelistofthegeographicpositionsofDanishchurch-towersfromtheDanishOrdnanceSurvey (KMS). Because a substantial part of thechurches were used as geodetic reference pointson theoldmaps too, they easily canbe identifiedandusedasreferencepoints.Thismadeitpossibletodigitize (vectorize) features from themaps andtransfer the features to geo-referencedmap-layersinaGIS-system.ThecoastlineandthehighwaysofDenmarkonthemap(Fig. 2)werecreatedwiththis technique.Theresultingmapofhistoricroadnetworksisa

Iron Age War Booty Offerings and Historic Highways

Already in theearly IronAgewefind thefirstof-feringsofwarbooty thatbecomecommon inpre-dominantly the lateRomanandMigrationperiod.Approximately 20 locations containing war bootyofferingsareknownandtypicallyeachhasnumer-ous,uptofivedepositions,coveringthewholeperi-odinquestion.Thefindsarecharacterisedbyalargeamount ofweapons, personal equipment forwar-riors, tools,oftenwagonsorboats,andotherarte-factsneededforanarmyinthefield;commonly,theobjectsarerituallydestroyedandarealwaysfoundinlakesorbogsites.ByreferencetothewritingsofCaesar, Tacitus and Orosius, they are interpretedasgiftsofgratitudetothegodsaftersuccessfulvic-toriesover invadingarmies, and theequipment isthus seen as the equipmentbelonging to a beatenarmy, at some locations of at least 200–400 men (Ilkjær / Lønstrup1982).Comparedtothedistribu-tionofthemedievalhighwaynetworkonFig. 4,wefindastrikingassociationbetweenwarbootyoffer-ingsandthehighways.Onlyveryfewsitesarenotlocatednearbytheroads.

Critical value at the 5% level withN=80is0.152).Inmedieval times the highways were used for

non-local transportation and communication. TheeldestDanish legislative sources from1241explic-itly differentiate between local roads and kongens hærstrate–theking’sarmiesstreet,translatedtomod-ern Danish as highway – landevej (Kroman / Iuul1967;Schovsbo2002).This isexactlyparalleled forinstanceinEngland“cynigesheiweg”andGerma-ny“Königs-Straße”(OED2007;Krünitz1773–1858).The maintenance of these roads was in medievalDenmark delegated to local peasants, since therewasnopublicadministrationto takecareof thosematters.Fromthe16thand17thcenturyitisknown,thatpeasantswerenotallowed touse these roadsingeneral–unlessthekingorsomeoneunderhisauthorityclaimedtheirrightfortransportationandinwhichcasethepeasantswereregardedastools,notindependentagents.From our analysis it seems as if the medieval
