Ethnoarchaeometric Study of the Traditional Cooking Ware Production Centre of Pabillonis (Sardinia): Investigating Raw Materials and Final Products
2010
Ethnoarchaeometry can be used to test assumptions in ceramic provenance studies. Within the Late Roman Cooking Wares (LRCW’s) commercialised in the Western Mediterranean some fabrics such as Fabrics 1.2, 1.6/1.7 and 1.9 (Fulford and Peacock, 1984) have been proposed to have a Sardinian origin. This motivated a specific project to explore the nature of cooking pottery on the island and the raw clays as well as the production technologies that have been used traditionally for their manufacture. In this paper, the traditional cooking pottery making in Pabillonis (Oristano province) was studied. First, a field survey in the area of Pabillonis was undertaken in order to locate the raw materials …
Charybdis glaucophylla (Asparagaceae), a new species from Sardinia
2012
Charybdis glaucophylla (Asparagaceae), a new species from Sardinia, is described and illustrated. It is a diploid species with 2n = 20 chromosomes growing along the rocky coast, sandy dunes and mountain top in the south-western part of the island. Within the genus, this species results taxonomically well isolated and differentiated due to relevant morphological and phenological features, such as the leaves wide and short, very rigid and glaucous-pruinose, as well as the very late foliation (winter). It shows only some relationships with C. pancration for the whitish bulb tunics and the diploid chromosome complement, and with C. maura and C. aphylla due to the glaucous leaves.
Indagine fitosociologica sulle praterie a Brachypodium retusum (Pers.) Beauv. della Sardegna.
2005
The grasslands characterized by the dominance of Brachypodium retusum occurring in Sardinia are examined. These communities, belonging to the Thero-Brachypodion ramosi alliance (Lygeo-Stipetea class), are quite widespread in the Island, where they usually grow on carbonate substrata from the sea level up to 1300 m of altitude. On the basis of several phytosociological relevés, it has been possible to recognize six associations well-differentiated from the floristic, ecological and syndynamic point of view. The autonomy of these associations is also supported by a numerical multivariate analysis based on quantitative data (dendrogram and P.C.A.). The associations surveyed are the following: …
I Barrai, picapedrers cagliaritani della seconda metà del Cinquecento. Stato degli studi e nuove ipotesi
2014
This essay is focused on the Barrai family, a group of stonecutters operating in Cagliari between 15th and 16th centuries. The family played a leading role in the construction and diffusion of star-shaped rib vaults in the late Sardinian 16th centuries religious architecture. The study attempts to systematize available evidence and information about the Barrai family in order to provide a starting point for further investigation. New hypotheses about the family’s genealogy and activity during the second half of the 16th century are also explored.
Ricostruzione virtuale delle crociere dell'aula della chiesa di San Domenico a Cagliari (XVI sec.)
2016
Il saggio affronta la ricostruzione virtuale delle crociere dell’aula della chiesa di San Domenico a Cagliari, distrutta nel 1943 dai bombardamenti alleati che colpirono la città. La ricostruzione virtuale, combinando gli strumenti dell’indagine storica e della rappresentazione digitale, è stata impiegata per comprendere il processo costruttivo della copertura dell’aula. Lo studio ha inoltre permesso di elaborare una più corretta interpretazione dei dettagli linguistici e delle caratteristiche costruttive delle crociere, consentendo di elaborare nuove ipotesi sulla fabbrica, attraverso la comparazione con architetture coeve. This paper focuses on the 3D virtual reconstruction of the star-sh…
Introduzione a: FUOCO E CARBONE : le tradizioni dei carbonai
2022
L'introduzione al volume: Fuoco e carbone. Le tradizioni dei carbonai sottolinea un’accorta indagine sul lavoro dei carbonai sardi, sulle fasi di produzione del carbone, sull’influenza che hanno avuto le maestranze toscane nel trasferimento di competenze e abilità sui carbonai locali, sul rapporto uomo-mondo vegetale che trovava massima espressione nel “processo di personificazione” della carbonaia con l’attribuzione di nomi e appellativi. Lo studio indaga, inoltre, le prime attestazioni di utilizzo del fuoco da parte degli uomini e gli impieghi ergologici e sociali che proprio il fuoco ha assunto nel tempo, la sua dimensione simbolica, quella linguistica, l’universo eterogeneo di pratiche …
MIS 5.5 highstand and future sea level flooding at 2100 and 2300 in tectonically stable areas of central mediterranean sea: Sardinia and the pontina …
2021
Areas of the Mediterranean Sea are dynamic habitats in which human activities have been conducted for centuries and which feature micro-tidal environments with about 0.40 m of range. For this reason, human settlements are still concentrated along a narrow coastline strip, where any change in the sea level and coastal dynamics may impact anthropic activities. We analyzed light detection and ranging (LiDAR) and Copernicus Earth observation data. The aim of this research is to provide estimates and detailed maps (in three coastal plain of Sardinia (Italy) and in the Pontina Plain (southern Latium, Italy) of: (i) the past marine transgression occurred during MIS 5.5 highstand 119 kyrss BP
Combined approaches to identify genomic regions involved in phenotypic differentiation between low divergent breeds: Application in Sardinian sheep p…
2019
Selective breeding has led to modifications in the genome of many livestock breeds. In this study, we identified the genomic regions that may explain some of the phenotypic differences between two closely related breeds from Sardinia. A total of 44 animals, 20 Sardinian Ancestral Black (SAB) and 24 Sardinian White (SW), were genotyped using the Illumina Ovine 50K array. A total of 68, 38 and 15 significant markers were identified using the case–control genome-wide association study (GWAS), the Bayesian population differentiation analysis (FST) and the Rsb metric, respectively. Comparisons among the approaches revealed a total of 22 overlapping markers between GWAS and FST and one marker bet…
Hypericum scruglii sp. nov. (Guttiferae) from Sardinia
2010
A new species of Hypericum (Guttiferae) from Sardinia, H. scruglii, is described and illustrated. It occurs on damp soil, near springs or streams with freshwater, where it grows with numerous hygrophytes. This diploid species (2n � 16) belongs to the sect. Adenosepalum and is closely related to H. tomentosum, a species widespread in the west Mediterranean region. During field investigations in Sardinia, very peculiar populations of Hypericum L. were found occuring on damp soils and limited to calcareous substrates. These plants showed a close morphological and ecological relationship with H. tomentosum L., a species belonging to sect. Adenosepalum Spach. As emphasized by Robson (1996), the …
