The production of traditional building materials in Oristano (Sardinia, Italy)

2016

The study of ceramic-making communities which employ traditional practices can provide insights into the raw materials and techniques used over the centuries in a particular territory. The archaeometric study of ceramic products and of the raw materials used in their production is an effective complement to the existing ethnographic information. This paper focuses on the brick and tile making tradition of Oristano, a town in Central-Western Sardinia (Italy). Applying a combination of techniques, it includes an extensive analysis of traditional handmade and early industrial bricks and tiles, and a study of the local clays that may have been used as raw materials. Although we were unable to s…

New distribution and taxonomic information on Callitriche (Plantaginaceae) in the Mediterranean region

2017

This article presents new records of water-starworts (Callitriche sp. pl.) from the Mediterranean basin, resulting from review of herbarium specimens and field work. Callitriche brutia var. naftolskyi is stated as a new combination and confirmed from Greece (Lesvos and Milos), Israel, Italy (Sardinia and Sicily), Libya, Morocco and Syria; C. lusitanica from Greece (Lesvos), Israel and Italy (Sardinia and Sicily); C. brutia var. brutia has been known from Greece for some time but is confirmed from Lesvos and Milos; C. obtusangula and C. truncata subsp. truncata are both confirmed from Sardinia and Sicily, while the latter is also confirmed from Syria. Callitriche lenisulca and C. stagnalis a…

First successful eradication of invasive Norway rats Rattus norvegicus from a small Mediterranean island (Isola delle Femmine, Italy)

2019

Invasive alien species, once introduced, may affect local biodiversity, both directly (e.g. by predation) and indirectly (e.g. by reducing the vegetation cover). Among those, rats (Rodentia, Muridae) are listed among the most invasive species, exerting strong impacts particularly when introduced to island ecosystems. Accordingly, black rats Rattus rattus have been eradicated from a number of islands in the Mediterranean basin to protect breeding seabirds. Where the larger Norway rat Rattus norvegicus is present, extent of damage may be even higher. In our work, we present the results of the first eradication program dealing with Norway rats in a small Mediterranean island (Isola delle Femmi…

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.

LATE ROMAN COOKING WARES FROM NORA (SARDINIA): INTERIM ARCHAEOLOGICAL AND ARCHAEOMETRICAL STUDY.

2010

This contribution aims to present the interim results of an archaeological and archaeometric research on the cooking wares from the central quarter of Nora (Cagliari, Sardinia) where a team from the University of Milano identified several Late Roman residences. The morphological analysis of the different groups has put in evidence a low variation of the types except for their size. The archaeometrical data show that most of the analysed materials may correspond to a local or regional production (with certain degree of variation) of cooking wares widely used in Nora in the Late Roman Period. It is important to stress that petrographic analysis shows that the compositional characteristics of …
