1. Introduction

Thenorthwestern Mediterranean is characterisedby rivervalleysandlowlands,borderedbysaltwaterlagoons (Fig.1).Itstwomainrivers(andtheirtributaries)arethe RhônetotheeastandtheEbrotothewest.ThePyrenees massif,orientedeast–westandroughlyperpendicularto thecoastline, is the main mountain range. The Albères Massif,itseasternmostextension,variesinaltitudefrom over2000mtosealevel,andliterallyrunsintothe Mediter-ranean.This range divides the study area in two main sectorsthatroughlycorrespondtoCataloniaintheSouth andLanguedocintheNorth.

This region’s agrarian economy in historical times wasMediterraneanwiththemostcommoncropsinthe plains being vine, olives, a variety of fruits and winter cereals(naked wheat,barley).Thisagriculturaltradition can be traced to Neolithic settlements dating back to 5800–5600calBCinLanguedocandtoabout5500calBC inCatalonia (Antolín, 2016;GuilaineandManen,2007). Theseearlypopulationsalreadycombinedthecultivation of crops and livestock husbandry withthe exploitation ofnaturalresources.Mostofthearchaeobotanicalrecord dating back to the Neolithic consists of cereals: naked wheat(Triticumaestivum/turgidum),emmer(T.dicoccum), einkorn(T.monococcum),nakedbarley(Hordeumvulgare var. nudum),and hulled barley(H. vulgare var. vulgare) (Antolin,2016;Antolínetal.,2015;Buxó,2007;Marinval, 1993).Localcroptraditionsandspecificitiesseem there-foretohavetheirrootsinPrehistory,3000yearsbeforethe BronzeAge.

Thegoalofthispaperistoidentifyandstudythe con-tinuities,changesandregionalspecificitiesofagricultural resourcesthroughouttheregioninferredfrom archaeob-otanical analysesfrom the end of the Neolithic to the beginningofAntiquity.Thisperiodcorrespondstoaperiod ofabout1500yearscomprisingtheBronzeAgeandFirst IronAge.TheendoftheFirstIronAgewaschosenasthe study’sstoppingpointbecauseitcoincideswiththearrival of the first Greek, Etruscan and Phoenician colonies in bothCataloniaandLanguedoc,settlementsthatusheredin westernMediterranean’sintegrationintotheagricultural economyofAntiquity.

Thestudyoftheregionalcharacteristicsofagricultureis particularlyinterestingbecause,besidesgeographical dif-ferences,thisterritorywassplitupintodifferentcultural unitsthatvariedovertimeandoftenexperienceddifferent externalinfluences(Py,2012).Itmustbenotedthatthese archaeobotanicalanalysespresentanumberofchallenges stemmingforthemostpartfromthespatialandtemporal heterogeneityofthecorpus,aswellastheheterogeneous natureofthedata.

2. Materialsandmethods

The vast arc-shaped study area between the Ebro andRhone Riversincludesboth coastaland inlandsites throughout what are currently the administrative dis-trictsofLanguedoc-Roussillon(Gard,Lozère,Hérault,Aude, andthePyrénées-Orientalesdepartments)andCatalonia (Girona,Barcelona, Tarragona,and Lleida)(Fig.1).Most

ofthearchaeobotanicaldatacomesfromexcavations car-riedoutinthefourfollowingregions(Table1):Languedoc, Pyrenees,easternCatalonia,andwesternCatalonianplain. Thechronologicalframeworkincludesallthesitesdated tobetweentheearlysecondmillenniumBCandthe mid-dleofthefirstmillenniumBC,roughlyfrom2100to500 BC.Thistimeframecorrespondstoseveralchrono-cultural periodsthatvaryinnomenclatureandrangefromregion toregion:

• SouthofFrance:EarlyBronzeAge(2100–1700calBC), Middle/LateBronzeI(1600–1400calBC),LateBronzeAge II–III(1400–725calBC),FirstIronAge(750–500calBC); • eastern Catalonia: Initial Bronze Age (2300–1300cal

BC), LateBronzeAge (1350–750calBC), FirstIronAge (700–550calBC);

• western Catalonian plain: Full Bronze Age (2100–1650calBC),Segre–CincaGroupI(1650–1250cal BC), Segre–Cinca Group II (1250–1000cal BC), Segre–Cinca Group III (1000–800/750cal BC), First IronAge(750–550calBC).

Tofacilitatetheanalysis,thesitesweregroupedinthe followingbroadchronologicalperiods:

• Period 1 (2100–1350/1250cal BC): corresponding roughlytotheEarly/MiddleBronzeAge, InitialBronze Age,andFullBronze/Segre–CincaGroupI;

• Period2(1350/1250–750calBC):correspondingroughly, dependingonthearea, totheLateBronzeAge orthe Segre–CincaGroupIIandIII;

• Period3(750–600/500calBC):correspondingroughlyto theFirstIronAge.

Thearchaeobotanicalsampleswerecollectedon67sites over the last severaldecades.Some of thesesites have multiple levelsofoccupation withdifferent chronologi-calphasescorrespondingtothelistofperiodscitedabove

(Fig.1andTable2).Opensettlements,sometimesfortified,

arethemostcommontypeofsite.Theirnumberincreases in thelater chronologicalphases, while cavedwellings declinetoonly9%intheFirstIronAge(Fig.2).

Themethodologyandthesamplingsystemsalso var-iedfromsitetosite,givingrise,insomecases,touneven results. In fact, 35%of theanalysesare basedona sin-glesample(forthewholesiteorforspecificlevels),while 40%oftheanalysesdonotsurpass10samples.The meth-ods ofsample processing generallyallowedrecovery of alltypesofremains.Yet,thesizeofthesmallestsieving meshwasnotspecifiedinthepublicationsofadozensites. Furthermore,finesievingattensiteswasnotundertaken, leadingtoincompletearchaeobotanicalregisters.Mostof theseedsandfruitsrecoveredarepreservedinacharred form.Yetwell-preservedwaterloggedremainsatseveral settlements in southernFrance (LaConque, LaFangade, LaMotte,PortAriane)affordamorecompleteviewofthe plantresources.

Theunitofanalysistocarryout theCFAof thesites wasthechronologicalphase ifthesite wereto contain morethanone.Eachphase bringstogetherallthe sam-plesthatanalysedatthesiteforthatpeculiarchronological period.Inordertoobtainarepresentativerangeofdata, onlythephaseswithaminimumof50plantremainswere retained(vanderVeen,1992),reducingthenumberofCFA assemblagesfrom84to52.Bythesametoken,soasto assuretheproperperceptionofthestructureofthedata,it wasnecessarytoeliminateunusualtaxaproducing detri-mental “noise”.Therefore, only theplants present inat least5%oftheassemblageswereretained(Valamoti,2004;

vanderVeen, 1992)thus restricting theanalysesto32

taxa,ofwhich fiveweresupplementary(chaffofhulled wheat,chaffofundeterminedwheat,grains of undeter-minedwheatandbarley,seedsofcultivatedpulses).These were,infact,inaccurateidentificationsthatcouldleadto biasduetothediversityofencodingmethodsofthe differ-entresearchers.

Furthermore,theCFAcouldnotbeappliedtothetotal numberof remains since itreflects aboveallthe quan-tity of samples carried out at the sites, as wellas the randomnatureofpreservationofplantremains(Pearsall, 2000).Therefore,thenumberof remainswasconverted into percentages and then transformed into scores of

abundanceaccordingtoa semiquantitativescaleoffour classes (1=up to 2%; 2=2–15%, 3=15 to50%, 4≥50%), a method that allows a bettercomparison of the vari-etyoftypesofsitesandsamplingprocedures(Boubyand

Marinval,2004;Jacomet,2006;Robinson,2003).

Asecondapproachwasalsoconductedusinga Princi-palComponentAnalysis(PCA)ondataquantifiedbythe IndexofRelativeAbundance(IRA)followingtheresearch

ofHastorfetal.(2005).Theadvantageisthatitcombines

theconceptsoftaxaabundanceandubiquityintoa sin-gleindex.ThePCAresultsarenotpresentedbecause,on theonehand,theuseoftheIRAwouldreducetherange ofdatatoonly29assemblages,andsecondly,theresults confirmtheCFAwithoutofferingmore.

3.1.1. Languedoc

Although the number of sites with seed and fruit remainsisscarceinLanguedocintheEarly/MiddleBronze Age (Period 1), this period offers a variety of cereals such as hulled barley (Hordeum vulgare), naked barley (Hordeumvulgarevar.nudum),nakedwheat(breadwheat ordurumwheat,Triticumaestivum/turgidum),andhulled wheat (emmer,Triticum dicoccum and einkorn, Triticum monococcum).Hulledbarleyandhulledwheatare predom-inantduringtheLateBronzeAgeandtheFirstIronAge, whereas nakedwheatis equivalenttoemmer.TheLate BronzeAge(Period2)seestheintroductionofcultivated millet,especiallycommonmillet(Panicummiliaceum) fol-lowed by Italian millet (Setaria italica). The emergence ofspelt(Triticumspelta),recoveredinlargequantitiesat BaumeLayrou(Boubyetal.,2005),isnoteworthy(Fig.3). Naked barley(Hordeum vulgare var. nudum),in turn, is residual.Chaff,inparticularthatofemmerandeinkorn,is alsoconsiderablethroughoutallthechronologicalphases. Barley andnaked wheatchaff,onthecontrary,are less common.

Broadbean(Viciafaba)istheonlypulsethathasbeen identifiedintheEarly/MiddleBronzeAge(Period1)sites, whilethisvarietyintheLateBronze(Period2)andFirst IronAge(Period3),althoughmorecommon,israndom, andapparentlydoesnotplayanimportantrole.Lentil(Lens culinaris)andgrasspea(Lathyruscicera/sativus)are proba-blythemostcommonpulses.Flax(Linumusitatissimum) isfoundintheEarly/MiddleBronzeAge(Period1)andthe LateBronzeAge(Period2)intheformofseedsandcapsules. Furthermore,opiumpoppy(Papaversomniferum)isknown intheLateBronzeAge(Period2)andcamelina(Camelina sativa)intheFirstIronAge(Period3).Theselasttwotaxa havebeendetectedonlyinLanguedocpartlyduetotheir presenceatwetlandsites.Inthisregion,theirubiquityis similartothatofpulses.

Fromthedataobtainedinthisstudy,wecaninferthat theCFAprovidesinterestinginformationaboutearlyplant exploitationintermsofspatialorganisationand chrono-logicalchanges.

Tobeginwith,theoverallresultscorroboratethe impor-tantroleof cerealscompared tothat ofothertaxasuch aspulsesandfruit.Ofcourse,itmustbeborneinmind thatcharringfavoursthepreservationofcereals. Further-more,thereisamarkedincreaseintheuseofhulledbarley throughouttheterritory,whilenakedbarley, characteris-ticofthePyreneesandLanguedocinthePeriod1,suffersa cleardeclinetowardthebeginningofthefirstmillennium. Asimilarsituationoccurs ineasternCatalonia,although nakedbarleyisnotasprevalentintheearlierchronological phases.ThewesternCatalonianplain,inturn,is charac-terisedbyitsabsence.

Two species, olive and grapevine, are particularly importantduetothevaluetheircultivationwillattain dur-ing theIronAge. Olives intheFirst IronAge(Period 3) areonlyknownattwosettlementswithevidenceofGreek influence,notablySanMartíd’EmpúriesandIllad’en

Reix-ach(Buxó,2008).Althougharchaeobotanicalremains of

olives arescarce, it cannotberuled out thattheywere cultivatedatthistime.

Dataregardinggrapevinearenowmoreabundantand informative. The number of charred grape pip finds is progressivelyincreasingattainingubiquityvalues compa-rable tothoseof minorcereals (millet)duringthe First Iron Age (Period 2). This points out to a growing eco-nomicsignificanceofvine.Thepresenceofthisfruitfrom the7thcenturyBCinlargequantitiesatindigenoussites withPhoenicianinfluencessuchasTuródelaFontdela CanyaorSantJaume/Masd’enSerrà(Lópezetal.,2011), and/orinassociationwithcertainseedswithclear domes-ticmorphologynotably atCougourludeoratSantMartí d’Empúries(FigueiralandBouby,unpublished;Buxó,2008) indicatesthatitscultivationalready playedasignificant roleatthetime.

OtherimportantconcentrationsofVitisintheEbro Val-ley,severalhundredkilometresinlandfromthestudyarea, date to the 7th century BC. This is the case of Cabezo dela Cruz(Zaragoza)(PérezJordà 2009)and Altodela Cruz (Navarra)(Cubero,1990).These examplesserve as evidenceoftherapidspreadofviticultureintheIberian Peninsula. Thesefindsreinforcetheideathatviticulture wasalready establishedinthe7thcenturyintheregion andthatitsincreaseinubiquity,althoughnotinallcases quantifiedbyahighnumberofremains,cancorrespond toitsgeneralexpansion.Thisspreadvariesintimefrom sitetosite.GrapecultivationinsouthernFrance,notably intheRhoneValleyandthecoastalplainofLanguedoc,for example,isnotrecordedbeforethesecondhalfofthe6th orpossiblythe5thcenturyBC(Bouby,2014;Boubyetal.,

2014;PyandBuxó,2001).

Grapevinecultivationalsomarksaturningpointinthe developmentofagriculture.Infact,throughoutallofthe BronzeAge,despiteseveralinnovations,theagricultural systemremainedbasicallyunchanged.Fruittrees,initially intheformofgrapevinesandlaterolive(andfig)trees,are specieswithadelayedreturnthatbreakwithan agricul-turalrhythmthat,uptothen,wasrootedonlyonobtaining immediatereturns,intheformofgrainsandpulses.The addition of arboriculture by the northwestern Mediter-raneanpopulationthereforeimplieslong-termtiestotheir territorybecausethesetypesof cropsrequireperennial plantations.

Thequestionofwhetherthecultivationand domesti-cationofgrapesresultedfromthedynamicsofindigenous agricultureorasaconsequenceofMediterraneancolonial influenceiscompelling.Thearchaeologicalrecordatthis stagecannotprovideaclearanswer.Nonetheless,itcannot beruledoutthatthetraditionofindigenousarboriculture wasexploitedbycolonialcontactsforwineproduction.

Theincreaseinrelevanceofviticulture,togetherwith theexpansionofmillets,andtheconsolidationofhulled

TurningtothesituationofcerealsintheSouth,thatis, in theregionofValencia andAndalusia, there are little changes asnaked wheats and barleys remain predomi-nant.Atransitionfromnakedbarleytohulledbarleyalso takes place in the Bronze Age. This changeis not syn-chronouswiththatoftheregionofValenciaasitdisappears inthemiddleofthesecondmillennium,whilein Andalu-sia it remains an important crop until the Late Bronze Age. However,after this period, nakedbarleyalso van-ishes(Pérez Jordà,2013; Rovira,2007; Stika and Heiss,
