InRetrospect Neolithic activity atKnockadoon, LoughGur, Co. Limerick, 50yearson1 GabrielCooney SchoolofArchaeology, University CollegeDublin,Dublin4 Sean P.Ó Ríordáin, MRIA, Professor ofCelticArchaeology atUniversity College Dublin(UCD), diedin1957attheageof52.Hewasatthepeakofhiscareer, engaged inanongoing research project atTarawhere hehadundertaken excavations atthe Rath oftheSynods (Ráith naSeanad, Grogan etal. forthcoming), Ráith naRig(Roche2002) andtheMoundoftheHostages (DumananGiall)where a further seasonofwork was carried outbyhissuccessor inUCD, Professor Ruaidhri deValera(O' Sullivan 2005). Ó Ríordáin 'swork atTaraturned outtobethe final actofa very impressive engagement inarchaeological research, much ofitpublished intheProceedings oftheRoyalIrish Academy. His paperspublished therein included thoseon hisseriesofexcavations on the Curragh, Co. Kildare(Ó Ríordáin1950a); his consideration of Roman material inIreland (Ó Ríordáin 1947a);andmajorexcavations atCush,Co. Limerick (Ó Ríordáin 1940),Garranes, Co. Cork(Ó Ríordáin 1942),Ballycatteen, Co. Cork(Ó Ríordáin andHartnett 1943),andLetterkeen, Co.Mayo(Ó Ríordáin andMacDermott 1952);that madea very significant contribution toourunderstanding ofearly Christian orearly medieval Ireland. Theco-authored volume onNewgrange andthe Bendofthe Boyne that appeared after hisdeath (Ó Ríordáin andDaniel 1964)demonstrated that hewasalsovery actively involved inthestudy ofthepassagetombs oftheBendofthe Boyne.SeanP.Ó Ríordáin 'simpact onIrish archaeology hasbeenoutlined invarious papers(O'Kelly 1957;Cooney1997a;de hoir2002; Wallace2004;Waddell2005, 225-6) andas Waddell (2005,225) hascommented Ó Ríordáin 'swork atLoughGur occupiesa central placeinhisachievement andcareer. From1936to1954(with a break in1952-3)heworked intheLoughGurarea ofsouth-east Co. Limerick, whereas heputit,'there is a smalllakesetina group oflimestone hills'(Ó Ríordáin1954,298). Fifty yearson,hisresearch programme inthisareastillranks as arguably themostintensive excavation-based investigation ofa landscape anywhere inIreland (Grogan 2005a,47), matched inscaleonlyover thelastdecadeor so bythearchaeological survey andexcavation associatedwith majorinfrastructural developments suchas motorways. Ó Ríordáin 's workbuilton existing research (Windle1912;O'Kelly1942,1943a,1943b,1944)andinvolved the 1Thisretrospective piecerelates toSeanP.Ó Ríordáin, 'Lough Gur excavations. Neolithic andBronze Agehouses onKnockadoon', Proceedings oftheRoyal Irish Academy 56C (1954), 297-459. Proceedings oftheRoyalIrish Academy Vol.107C,215-225© 2007RoyalIrish Academy GabrielCooney excavation ofa widerangeofsitesintheLoughGurarea.Thesesitesincluded the Carraig Ailleringforts andrelated structures andactivity (Ó Ríordáin 1949),barrows atRathjordan (Ó Ríordáin 1947b,1948),wetland sitesatRockbarton (Mitchell andÓ Ríordáin 1942)andBallingoola (Ó Ríordáin 1950b),thewedgetomb atLoughGur (Ó Ríordáin andÓ h-Iceadha 1955)andthelargestone circleatGrange (Ó Ríordáin 1951).Butgeographically at theheartoftheLoughGurarea is theKnockadoon Peninsula around which LoughGurcurves onthree sides(theexception beingtothe eastwhere there is marsh). Ó Ríordáin 's (1954) excavation ofprehistoric settlement sitesthere wascentral notonly tohisinterpretation oftheprehistory oftheLoughGur areabutalsotoitsplaceandroleina wider understanding ofprehistory inIreland. Itishisdiscussion oftheresults oftheexcavation ofnineopenorunprotected siteswith structures ofrectangular andcircular form (SitesA-I) onKnockadoon that is thefocusofthisretrospection (Pis I andII). Ó Ríordáin evaluated theresults and detailed whathethought werethesignificance ofthesites'from twoviewpoints that ofhousestructure andthat oftheaccompanying material equipment, especially thepottery' (Ó Ríordáin1954,443). He also excavated a seriesofenclosedsites on Knockadoon(CirclesJ,K, L and Sites 10 and 12),theresults ofwhichwere subsequently published intheProceedings oftheRoyalIrishAcademy (Grogan and Eogan1987).Grogan andEogan(1987,467-90) madethepoint that theseenclosed sitesand theopen sitesdetailedby Ó Ríordáin(1954) shouldbe considered in conjunction. Also,intheir general discussion they provide animportant assessment of Ó Ríordáin 's workandinterpretations inthelight ofarchaeological knowledge in themid-1980s. Subsequently, there hasbeenfurther excavation onKnockadoon and valuable reassessment ofearlier work byCleary (1993,1995,2003).Theresults ofthe Discovery Programme's North Munster project (Grogan 2005a,2005b)haveplacedÓ Ríordáin 'swork ina wider landscape andcultural context (see discussion inGrogan 2005a,47-62; seealsoGrogan 1989).Attheendofthediscussion inthe1954paper Ó Ríordáin reflected that thepublication ofhisresearch ontheKnockadoon siteswould helptoprovide a background andframework for thediscussion ofother similar sites andthat further work atLoughGurwouldhelptofillinthegaps(Ó Ríordáin 1954, 456). Itis inthiscontext that I wanttoconsider current assessments ofthematerial equipment, specifically thepottery (Fig.1),andthehousestructures onKnockadoon (Fig. 2), particularly as theyrelateto ourinterpretation andunderstanding ofthe Neolithic period inIreland. Itisworth remembering that wenowhavea muchlonger prehistoric chronology thanÓ Ríordáin, working before theadvent ofradiocarbon dating, wouldhaveenvisaged. Therehas been a carefulteasingout and reassessment of Ó Ríordáin 's arguments regarding theprehistoric pottery sequence bya number ofarchaeologists. As Grogan(2005a, 53) hasputitthepottery is thekeyto dating thesequenceof prehistoric activity atKnockadoon, basedondevelopments inourunderstanding of Irishprehistoric ceramics. Ó Ríordáin hadusedstratigraphy, particularly atSiteC, todatethepottery, buthealso recognised that thiswasproblematic becauseofthe continuity ofprehistoric activity onthepeninsula (Ó Ríordáin 1954,322,341).Inan important paper, Kelly(1978) pointed outthat, giventhethinness ofthesoilcover overlimestone bedrock, thelackofwell-defined stratigraphy andthelongsequence ofactivity, anadmixture ofmaterial ofdifferent datesmight beexpected.
