Il Dioniso delle "Baccanti" e i "piegatori di pini". Polivalenza di un'immagine leggendaria
2021
This paper investigates the mythical and ritual background of Dionysus’ representation as “fir-bender” in Euripides’ "Bacchae" (ll. 1061 ff.), in an attempt to shed light not only on the dramaturgical aspects of the tragic plot, but also on the cultural categories that make this representation intelligible to the Athenian audience at the end of the fifth century BC. Following Louis Gernet’s historical-anthropological approach based on the notion of "polyvalence des images", this paper aims to define a mythical pattern – the connection between the bending of a tree and the dismemberment of a human victim – already attested in the Attic legend of Theseus and Sinis, in which both characters se…
Phytosociological notes on the Lygeum spartum grasslands from Crete.
2002
Lygeum spartum grasslands from Crete have been studied by the application of the phytosocological method. A new alliance, Scorzonero creticae-Lygeion sparti and three new associations and have been recognized. The first, Limonio hyssopifolii-Lygeetum sparti occurs on halomorphyc badlands in the Sitia territory (NE Crete); the second Erodio crassifolii-Lygeetum sparti grows on heavily eroded clayey outcrops close to Hyerapetra (SE Crete); the third Convolvulo oleifolii-Lygeetum sparti, substitutes the previous one some Km eastward from Hyerapetra, on stratified marls alternated to conglomerates. Within the last association, two subassociations have been recognized: limonietosum roridi (typic…
The Greeks in the West: genetic signatures of the Hellenic colonisation in southern Italy and Sicily
2015
Greek colonisation of South Italy and Sicily (Magna Graecia) was a defining event in European cultural history, although the demographic processes and genetic impacts involved have not been systematically investigated. Here, we combine high-resolution surveys of the variability at the uni-parentally inherited Y chromosome and mitochondrial DNA in selected samples of putative source and recipient populations with forward-in-time simulations of alternative demographic models to detect signatures of that impact. Using a subset of haplotypes chosen to represent historical sources, we recover a clear signature of Greek ancestry in East Sicily compatible with the settlement from Euboea during the…

Origin and distribution of methane and C2-C6 hydrocarbons in hydrothermal and cold gaseous emissions in Greece
2015
The Hellenic territory has a very complex geodynamic setting from a long and composite geological history, giving rise to an intense seismic activity deriving and favoring the occurrence of many cold and thermal gas manifestations. Geogenic sources release huge amounts of gases, which have a significant impact on the global balance of the subaerial Carbon Cycle. The study of the geochemistry of the natural gas emissions of the Greek territory is actually underway. In the present work, we focus on methane and light hydrocarbons (C2-C6) to define their origin. Concentrations of methane range from < 2 to 915,200 mmol/mol and its isotopic ratios cover a wide range (d13C from -79.8‰ to +16.9‰…
Origin of methane and light hydrocarbons in the gas manifestations of Greece.
2017
The geologic emissions of greenhouse gases (CO2 and CH4) give an important natural contribution to the global carbon budget. However, the contribution of these emissions to the global carbon cycle and their possible role on the climate change remain still poorly quantified (Guliyev and Feizullayev, 1997; Milkov, 2000; Etiope et al., 2015 and references therein). Methane, the most abundant organic compound in Earth's atmosphere, may be created either from existing organic matter or synthesized from inorganic molecules. Accordingly, it can be differentiated in two main classes: a) biotic (either microbial or thermogenic) and b) abiotic. For this study, 115 gas samples of fumarolic, thermal an…
Extreme isotope fractionation of hydrothermal methane due to oxidation processes in hot springs of Central Greece
2017
The Greek territory belongs to the geodynamically active Alpine-Himalayan orogenic belt. As such, it shows intense seismic activity, active volcanic systems and areas of enhanced geothermal fluxes. One of these areas is the Sperchios basin and the northern part of Evia island in central Greece, which present widespread thermal manifestations [1]. Five of them with temperatures from 33 to 80°C present bubbling gases whose dominating species are either CO2 or N2. All gases contain from 27 to 4000 ppm of CH4. The isotopic composition of CH4 in these gases covers a wide range with δ13C values ranging from -21.7 to +16.9‰ and δ2H values ranging from -124 to +301‰. The hottest manifestation displ…
Gas geochemistry and CO2 output estimation of Milos Island (Greece)
2018
Several gas samples have been collected from natural gas manifestations in the island of Milos. Most of them are located underwater along its coasts, whereas three anomalous degassing fumarolic areas (Kalamos, Paleochori and Adamas) were identified on land. Almost all the gases have CO2 as the prevailing gas species, with concentrations ranging from 88 to 99% for the samples taken underwater, while the on-land manifestations present a wider range (15-98%), being sometimes heavily contaminated by air. Methane reaches up to 1.0%, H2 up to 3.2% and H2S up to 3.5% indicating a hydrothermal origin of the gases. The isotope composition of He shows values ranging from 2.55 to 3.39 R/RA, highlighti…
Minerali, piante, animali e uomini: indagine lessicale sul rapporto tra i regni naturali e l’ambiente nella Grecia antica
2021
L’articolo indaga il rapporto che sussiste nella Grecia antica tra la terra e i cosiddetti «regni naturali» (minerale, vegetale, animale, umano) alla luce del lessico utilizzato per indicarlo e mostra che, a differenza di quanto avviene presso di noi, esso è spesso analogo per tutti e quattro gli ambiti. L’azione della terra (o altri elementi eco-sistemici) nei confronti degli elementi che appartengono ai diversi regni, infatti, è tendenzialmente designata dagli stessi verbi (vengono presi in considerazione phýein, ghennán, bóskein, tréphein, phérein, anadidónai): la terra phýei (e ugualmente possono essere usati anche gli altri verbi) sia uomini, sia animali, sia piante, sia minerali. Th…
