The dry stone wall of 'Paretone dei Greci': an anthracological approach

International audienceDry stone constructions are a common occurrence in many Mediterranean landscapes. One of these structures known as "Paretone dei Greci" (Taranto, Southern Italy), was subject to an archaeological investigation. Soil and sediment material within this wall, as well as those above and below it, were sampled and processed for archaeobotanical studies. In this manner it was possible to understand its building technique as well as giving it a chronological context. Through an anthracological analysis it was possible to insert the "Paretone" within the surrounding agricultural landscape, thus better highlighting its function in relation to the history of the territor

The introduction of Citrus in Italy with reference to the identification problem of seed remains

While some consensus exists about the roles of southwestern China and northeastern India in the origin and diversification of the genus Citrus, the scarcity of its archaeological remains, as well as some methodological limits in unequivocally identifying taxa, do not facilitate reconstruction of the tempo and mode of spread of the genus towards other areas, notably the Mediterranean. Recent discoveries of archaeobotanical macro-remains (seeds and fruits) and pollen records from some important Italian sites in the Vesuvius area and Rome can be used to shed new light on this history. However, due to their morphological variability and the changes derived from the preservation processes, Citrus seeds appear difficult to recognise. In this paper, we present criteria to facilitate their precise identification, based on the observation of the morphology of modern seeds, and most of all the seed-coat patterns. The reference material consisted of "archaic" varieties of C. medica L. (citron), C. × limon (L.) Burm. f. (lemon) and seeds of C. × aurantium L. (bitter or Seville orange), C. × aurantiifolia (Christm.) Swingle (lime) and C. reticulata Blanco (tangerine, mandarin orange). Considering the fact that the general morphology of seeds, especially when mineralised, can confuse the identification of Citrus with Maloideae types, we also add criteria for the recognition of Cydonia oblonga Mill. (quince), Malus domestica Borkh. (apple), Pyrus communis L. (pear), Sorbus aria (L.) Crantz (whitebeam) and S. domestica L. (service tree). The observation of the keels and cell patterns was mostly useful to identify new material from Pompeii and Rome dating from the 3rd/2nd century b.c. and the Augustan period around the beginning of the Common (Christian) Era as C. medica L. (citron) and C. cf. × limon (L.) Burm. f. (possible lemon). The classical Greek and Latin sources helped us to understand the use and status of citrus fruits in the ancient world and, in combination with all available archaeobotanical remains compiled in this paper, have allowed us to discuss the spread of Citrus from its regions of origin to the eastern Mediterranean and then within the Mediterranean. © 2013 Springer-Verlag Berlin Heidelberg

Palaeovegetational reconstruction of the Krios valley, northern Achaea (Greece): archaeobotanical analysis conducted as part of the Aegialia Survey Project

Since 2001 the Aegialia Survey Project (A.S.P.) has sought to reconstruct the dynamics of human occupation in Aegialia, northern Achaea (Greece). In doing so it has followed a multidisciplinary approach, with the involvement of various skills and institutions.Depuis 2001, l’Aegialia Survey Projet (ASP) a cherché à reconstruire la dynamique de l'occupation humaine dans la région de Aegialia, dans le nord Achaïe (Grèce). Ce faisant, on a suivi une approche multidisciplinaire, avec la participation de diverses compétences et institutions. La recherche dans la vallée de Krios impliquait aussi la reconnaissance et l'enregistrement de la flore actuelle dans la région

A multidisciplinary study of archaeological grape seeds.

We report here the first integrated investigation of both ancient DNA and proteins in archaeobotanical samples: medieval grape (Vitis vinifera L.) seeds, preserved by anoxic waterlogging, from an early medieval (seventh-eighth century A.D.) Byzantine rural settlement in the Salento area (Lecce, Italy) and a late (fourteenth-fifteenth century A.D.) medieval site in York (England). Pyrolysis gas chromatography mass spectrometry documented good carbohydrate preservation, whilst amino acid analysis revealed approximately 90% loss of the original protein content. In the York sample, mass spectrometry-based sequencing identified several degraded ancient peptides. Nuclear microsatellite locus (VVS2, VVMD5, VVMD7, ZAG62 and ZAG79) analysis permitted a tentative comparison of the genetic profiles of both the ancient samples with the modern varieties. The ability to recover microsatellite DNA has potential to improve biomolecular analysis on ancient grape seeds from archaeological contexts. Although the investigation of five microsatellite loci cannot assign the ancient samples to any geographic region or modern cultivar, the results allow speculation that the material from York was not grown locally, whilst the remains from Supersano could represent a trace of contacts with the eastern Mediterranean
