The cultural sequence spans from the Early Mesolithic to the Copper Age. Among the lithic materials a Sauveterrian production has been identified. Mesolithic artefacts were found not only in primary deposition layers but also in other disturbed stratigraphic units containing intrusive Neo-Eneolithic artefacts.RiassuntoRecenti ricerche nell’area dei massi incisi a Cemmo (Capo di Ponte, Brescia) effettuate dalla So-printendenza per i Beni Archeologici della Lombardia hanno messo in luce lembi di deposito antro-pico sul quale poggiano i massi stessi. La sequenza culturale del deposito archeologico indagato si estende dal Mesolitico all’età del Rame. Tra i materiali litici è stata individuata una produzione di tipo sauveterriano che è stato possibile esaminare sia in porzioni di deposito in posto sia in altre contenenti materiali intrusivi neo-eneolitici.Redazione: Valeria Lencioni e Marco Avanzinipdf: http://www.muse.it/it/Editoria-Muse/Preistoria-Alpina/Pagine/PA/PA_48-2016.aspxMartini F., Lo Vetro D., Timpanelli L., Magri F., Poggiani Keller R., 2016 - Mesolithic findings from the area of the engraved boulders at Ce-mmo (Lombardia, Italia).

Preistoria Alpinavol. 48 2016Preistoria AlpinaISSN 2035-7699homepage: http://www.muse.it/it/Editoria-Muse/Preistoria-alpina© 2016 MUSE - Museo delle Scienze, Trento, ItaliaPreistoria Alpina, 48 (2016): 89-92IntroductionThe famous “Massi di Cemmo”, two engraved boulders dating back to the Copper Age, are located in the little valley of Pian delle Greppe, North of Capo di Ponte (Brescia), around 400 metres a.s.l. (Figg. 1, 2, 3). Recent archaeological researches performed in the area around the boulders have brought to light an anthropogenic deposit on which the rocks themselves lie. This deposit has been the focus of a stratigraphic excavation by the Soprintendenza per i Beni archeologici della Lombardia. The cultural sequence of the ar-chaeological deposits extends from Early Mesolithic to Copper Age (Poggiani Keller 1999-2000; 2009).The lithic assemblageSeveral in situ stratigraphic units underlying the Neolithic and Eneo-lithic layers have yielded lithic artefacts related to the Sauveterrian facies. Due to its paucity this Mesolithic assemblage is described here in its techno-typological and stylistic characteristics, which cannot be traced back to a typological structure (sensu Laplace).The group in situ is composed of 35 retouched pieces, 3 cores, 19 microburins, 226 débitage products (prevalently debris, secondarily unretouched blanks, rejuvenation blades, cores shaping and mainte-nance blanks). A hypermicrolithic crescent, a centripetal core (Fig. 4, n. 7) and few hypermicrolithic microburins (Fig. 4, nn. 5-6) were found in secondary position.Raw material, technologySome of the few useful finds for a diagnosis of the sources of the raw materials (most of the artefacts have a heavy white patina) are made of high quality flints that, by macroscopic observations, seem to refer to Lombardy formations (Maiolica, Selcifero Lombardo, Medolo) whose closest known outcrops are found in the reliefs located South of Lake Iseo (Baroni & Biagi 1997) and South-East of Lake Garda (Bar-field 1990). To these formations might refer some blanks extracted from small nodules and blocks gathered in areas not distant from the primary outcrops. Few items might be related to the Veneto-Trentino platform formations.In brief, with the reserve due to the nature of the sample and the lack of specific studies about flint source availability in the areas sur-rounding the site, we hypothesize that a part of the exploited flints come from areas more than 40 kilometres from Cemmo.Technological featuresThe reduction sequences are oriented to the production of hyper-micro and microbladelets for the manufacturing of  armatures of less than 10 mm in width. The rare larger laminar blanks (length over 35 mm) and the microflakes are used to make common tools. The main reduc-tion scheme is recognizable in some bladelets and in a small core, con-nected to the same technical system: direct percussion, basic prepa-ration of the striking platform, abrasion of the core overhang (Fig. 4, nn. 1-4, 8). To the same scheme can also be attributed a thick tablette from a semitournant core related to an initial phase of the core exploitation.Retouched artefactsThe retouched assemblage (here described following Laplace’s ty-pology 1964) is represented by 7 armatures and 28 common tools. The size of common tools is micro (length 16-25 mm) and small (up to 50 mm); the hypermicro (up to 15 mm) items are very rare. The armatures are equally micro and hypermicro in size.Fig. 1 - Cemmo (Lombardy, Italy). Site location. / Localizzazione del sito.Fig. 2 - Cemmo.

Baglioni).Preistoria Alpina, 48 (2016) / 91ArmaturesThe typical double backed point (Sauveterre) is lacking; the geometric armatures are represented by crescents and triangles al-ways carefully made. The armatures are listed below:• convex double backed point (PD4), symmetric, made on a wide microbladelet (Fig. 5, n. 8)• total unilateral rectilinear backed blade (LD2) on a narrow ipermi-crobladelet• partially retouched wide, microlithic crescent (Gm1)• two crescents (Gm1) obtained from two narrow ipermicroblade-lets (Fig. 5, n. 11)• scalene triangle (Gm3) on a wide microbladelet (Fig. 5, n. 10)• scalene triangle (Gm3) on a narrow ipermicrobladelet (Fig. 5, n. 9)Common toolsThe burins category consist of 3 items: one Simple axial burin (B2), one single angle burin (B3) and one probable retouched burin with oblique facet (B7). These burins are not accurate and made on flake (Fig. 5, nn. 1-2). The two end-scrapers consist of a item on a blade (G2), with rectilinear scraping edge, and a short item (G4), on a wide flake with a very irregular asymmetrical scraping edge (Fig. 5, nn. 3-4). Two of the three borers are made on microbladelets (Fig. 5, nn. 6-7); these items are very similar, in shape and size, to the armatures.The other tools share the partial and rough shaping, as well as a more or less peripheral retouch; this is the case of the blade-scrap-ers (8 items, all asymmetrical: six with inframarginal retouch, two with marginal retouch) and the flake-scrapers (5 items), as for two fragments of a blade/flake-scraper, for the two abrupt retouched flakes, for the two denticulates (a scraper and an end-scraper) and for the splintered piece (Fig. 5, 13). Among the common tools signif-icant is a transversal scraper (Skrobacz) whose morphology tends to subtectiform end-scraper (Fig. 5, n. 12).The Mesolithic assemblages of Cemmo generically fit the Nor-thern Mesolithic complexes of Sauveterrian facies, the evidence of which is also attested in Valcamonica at Cividate Camuno site (Mar-tini et al. this volume).
