The excavations at Torone, Mende, and some other sites have produced evidence of continuous contact between Chalcidice and southern Greece from early in the Iron Age. We can now understand more clearly the relationship between the earliest Greek settlers and those of the colonizing period, and we can tackle some problems of topography in the Chalcidian peninsula from a new angle.

AbstractFive out of ten ocellated skinks (Chalcides ocellatus) examined in Dubai between 2007 and 2010 were infected with cestodes of the genus Oochoristica. Out of the 36 collected tapeworms seven specimens were used to describe a new species. Oochoristica chalcidesi n. sp. belongs to the group of species with 25 to 35 testes arranged in two clusters. The lobes of the ovary are subdivided into 4–5 lobules in a similar way as O. ubelakeri described from Agama atra in Namibia. Both species differ in the presence of a neck, a lower number of mature segments in O. chalcidesi n. sp. and a different position of the cirrus pouch in relation to the ovary, as well as in the distribution of uterine capsulae in gravid segments.

Abstract The aim of this study was to characterize the local fauna of Hymenoptera parasitoids associated with Lepidoptera larvae in areas of reforestation and agrosilvopastoral systems at Fazenda Canchim (Embrapa Pecuária Sudeste, São Carlos, SP, Brazil). Lepidoptera larvae collected with entomological umbrella were kept in the laboratory until emergence of adults or their parasitoids. From those collected in the agrosilvopastoral system, emerged 267 specimens of hymenopteran parasitoids belonging to 16 genera: Braconidae, Agathidinae (Alabagrus), Braconinae (Bracon), Microgastrinae (Cotesia, Diolcogaster, Glyptapanteles, Pholetesor and Protapanteles), Orgilinae (Orgilus); Ichneumonidae, Campopleginae (Casinaria, Charops and Microcharops); Chalcididae, Chalcidinae (Brachymeria and Conura); Eulophidae, Entedoninae (Horismenus), Eulophinae (Elachertus and Euplectrus). From the Lepidoptera larvae collected in the reforestation, emerged 68 specimens of hymenopteran parasitoids, belonging to 8 genera: Chalcididae, Chalcidinae (Conura); Ichneumonidae, Pimplinae (Neotheronia), Campopleginae (Charops and Microcharops) and Braconidae, Microgastrinae (Apanteles, Diolcogaster, Distatrix, Glyptapanteles and Protapanteles). The results of this study suggest the occurrence of a wide variety of Hymenoptera parasitoids in the studied environments.

Metal hyperaccumulator plants represent a unique biological resource for scientific research and practical applications. Though essential, however, an adequate knowledge of the systematics of these plants is often missing. This is the case of Odontarrhena, a large but taxonomically critical group of nickel hyperaccumulators from Eurasia. We present a study on this genus in Albania, to fill a gap in our knowledge of this group from a major centre of diversity of metallicolous flora, and to contribute updated information to the Global Hyperaccumulator Database. Morphological and karyological analyses of material from field collections across all major serpentine outcrops in the country, in different years and seasons, allowed to delimit seven taxa: O. albiflora, O. chalcidica, O. moravensis, O. sibirica, O. decipiens, O. smolikana subsp. glabra and O. rigida. The three latter taxa have been long neglected and were resurrected in view of their clear distinctness, while commonly accepted taxa such as O. bertolonii subsp. scutarina and O. markgrafii were reduced to synonymy of O. chalcidica due to the lack of consistent differentiation. Polyploidy was prevalent, while diploid complements were typical of the two vicariant endemics O. rigida and O. moravensis. Types are indicated or newly designated for each entity, and nomenclatural issues are addressed based on in-depth studies of literature and herbarium material. Revised descriptions, phenology, habitat and distribution data are given for each taxon, as well as original iconographies and chromosome counts. A revised identification key is provided. Shoot nickel concentrations were determined to assess accumulation levels of taxa and populations in natural conditions and their potential for phytoextraction of this metal from the soil. With ca. 23000 and 17000 µg of Ni g-1 of shoot dry weight, respectively, the tetraploids O. chalcidica and O. decipiens were the most promising candidates, especially the latter for its robust habit.

Previous issue date: 2015-02-25<br>Uma revisão das espécies do grupo oiketicusi de Conura (Chalcididae, Hymenoptera) é apresentada. O grupo foi proposto por Delvare (1992) e reúne até o momento seis espécies [Conura basilica (Walker, 1864), C. elaeisis Delvare, 1993, C. fortidens (Cameron, 1909), C. giraulti De Santis, 1979, C. mexicana (Cresson, 1872) e C. oiketicusi (Cameron, 1913)]. Ao menos parte das espécies são parasitoides de Oiketicus sp. (Psychidae, Lepidoptera) e apenas suas descrições originais tratam de suas características morfológicas, sendo essas insuficientes para identificar as espécies devidamente. Logo, a maioria das espécies não é passível de reconhecimento utilizando-se a literatura. Séries de tipos de quatro espécies nominais foram analisadas. Os seguintes sinônimos serão propostos: C. elaeisis e C. oiketicusi como sinônimos juniores de C. basilica. São apresentadas redescrições para C. basilica, C. giraulti e C. fortidens. Foram feitas considerações sobre a identidade de C. mexicana e uma espécie não determinada é tratada aqui.<br>A Review of the species of oiketicusi group Conura (Chalcididae, Hymenoptera)

Full textAbstract:
Une étude de phylogénétique des Eurytominae (Hymenoptera : Chalcidoidea) a été effectuée en utilisant des données morphologiques. L'étude morphologique est basée sur un large échantillonnage (178 taxa et 150 caractères). L'analyse des données a été menée en parcimonie, en utilisant à la fois matrice complète et partielles. Les différentes topologies obtenues sont discutées en détail. Quelle que soit l'origine des données, les nœuds superficiels sont stables et robustes tandis que les nœuds profonds ne sont pas soutenus. Nos résultats permettent cependant de redéfinir les Eurytomidae sur la base d'une ascendance commune. Les Eurytomidae tels qu'ils ont été traditionnellement considérés sont clairement polyphylétiques. Les Heimbrinae apparaissent toujours comme le groupe frère des Chalcididae. Les Buresiinae sont restreints aux genres Buresium et Macrorileya. Ils forment le groupe frère des Eurytominae ; ces derniers apparaissent constamment comme un groupe monophylétique. Les Eurytomidae sont donc restreints à ces deux sous-familles. Les limites des genres les plus diversifiés (Aximopsis, Bruchophagus, Eurytoma, Philolema et Prodecatoma) sont reprécisées. Des diagnoses sont proposées pour les groupes d'espèces appartenant aux deux genres les plus importants (Eurytoma et Bruchophagus). Finalement, 22 nouvelles synonymies génériques 33 nouvelles combinaisons sont proposées. A partir de la phylogénie obtenue et connaissant les traits de vie du groupe externe (Buresiinae), il est possible d'inférer la biologie de l'ancêtre commun supposé des Eurytominae. Celui-ci fut probablement un parasitoïde ; toutefois de nombreuses dérives vers la phytophagie peuvent être mises en évidence à partir des arbres obtenus. Deux complexes d’espèces appartenant respectivement au genre Sycophila et au groupe rosae à l'intérieur du genre Eurytoma, ont été étudiés en utilisant la morphologie fine, la morphométrie et des données moléculaires. Des caractères pour discriminer les espèces jumelles sont fournis. Eurytoma caninae sp. N. Est décrit et Sycophila pistacina revalidé. Les données morphologiques sont confirmées par la morphométrie au niveau du complexe Sycophila biguttata. Les données moléculaires respectivement basées sur un gène mitochondrial (COI) et nucléaire (ITS2) corroborent également le diagnostic réalisé en morphologie<br>A phylogenetic study of the Eurytominae (Hymenoptera: Chalcidoidea) was undertaken using morphological data. The morphological study was carried out from a large sampling (178 taxa and 150 morphological characters). The analysis of the morphological data using parsimony was made with complete and partial matrices. The alternate topologies obtained are discussed in detail. The superficial nodes of the obtained trees, whatever the fields of data, are stable and robust but the deep nodes are unstable and not supported. The results nevertheless provide support for a redefinition of the Eurytomidae and a new partition of the genera. The study clearly demonstrates that the Eurytomidae in the traditionnal sense are polyphyletic. In all trees the Heimbrinae are the sister-group of the Chalcididae. The Buresiinae are redefined; they include the genera Buresium and Macrorileya. This subfamily appears as the sister-group of the Eurytominae which otherwise form a monophyletic group in all cladograms retrieved. A new classification is therefore proposed for the Eurytomidae, restricted to Eurytominae and Buresiinae. The limits of the genera Aximopsis, Bruchophagus, Eurytoma, Philolema and Prodecatoma are redefined. Species groups are precised for the two largest genera (Eurytoma and Bruchophagus). Finally, 22 new generic synonymies and 33 new combinations are proposed. According to the phylogeny achieved and the biology of the outgroup (the Buresiinae) it is postulated than the common ancestor of the Eurytominae was a parasitoid with many shifts to phytophagy during the evolution of the Eurytominae. Two species complexes respectively in the genus Sycophila and in the rosae species group of Eurytoma, using morphological, morphometric and molecular data were investigated. Diagnostic characters are provided for the recognition of sibling and closely related species. Eurytoma caninae sp. N. Is described and Sycophila pistacina revalidated. The fine morphology is confirmed with morphometric analyses in the S. Biguttata complex. Also molecular examination using two genes (cytochrome oxidase subunit I and the internal transcribed spacer region 2) ascertain our morphological observations

Full textAbstract:
L'état fédéral des chalcidiens de Thrace, colons eubéens, fut fondé vers 432, à la suite du synœcisme conseillé par perdiccas II de Macédoine pour des raisons de sécurité vis-à-vis de la flotte athénienne. Durant la première moitié du IVe siècle le koinon annexa une grande partie de la péninsule et joua un rôle important dans les affaires de la Grèce du nord en essayant de minimiser le degrés d'intervention des puissances comme Athènes, Sparte et la Macédoine dans les affaires chalcidiennes. Le monnayage fédéral débuta dans les années 420 dans le but de financer une partie des opérations militaires de Brasidas contre Athènes. Des tétroboles de poids thraco-macédonien selon le modèle de ceux frappés par Perdiccas II et Olynthe, cité principale de la confédération, continuèrent d'être frappés. Des tétradrachmes d'argent s'y a ajoutèrent vers la fin du Ve siècle. Le numéraire d'argent des chalcidiens est omniprésent dans les trésors trouvés à Olynthe et est également présent dans les trésors enfouis en Chalcidique durant la première moitié du IVe siècle. Les tétroboles de Perdiccas II et d'Acanthe furent assez importants aussi. Le monnayage de bronze fut adopté par les chalcidiens sous l'influence de Corinthe dans les années 410. Aux deuxièmes de l'obole s'ajoutèrent des quarts d'obole et des hémioboles vers la fin du Ve siècle. Les Bottiéens ont également frappé un monnayage de bronze en trois dénominations avec des types qui rappellent le monnayage chalcidien, durant la période de leur participation à l'état fédéral. L'affrontement avec Philippe II de Macédoine eut pour résultat la dissolution de la ligue et l'incorporation de la Chalcidique dans le royaume téménide<br>The chalcidians of Thrace, Euboean colonists, founded the federal state in 432. Their military operations against Athens as a result of their revolt and their alliance with Perdiccas II of Macedon and Potidaea during the last quarter of the fifth century gave them the possibility to become an important power. During the first half of the fourth century they were joined by other cities of the Chalcidic peninsula, like Torone, Potidaea, Sermylia and the Bottiaean federal state. Their silver coinage began in the 420s so as to pay the Brasidean mercenaries, and continued to 348 b. C. They struck heavy tetrobols, as Perdiccas II did, tetradrachms, diobols, obols and trihemiobols. Their gold issues on the attic standard date from the second quarter of the fourth century. The Chalcidians were the first state in north Greece to introduce a bronze coinage, some years before Archelaus. They were influenced by Corinth. Their relations with this city during the Peloponnesian war and the years that followed the peace of Nicias could explain this innovation. An important number of cities followed them. They struck three denominations of bronze coins: hemiobols, tetartemoria and chalques. The coinage in gold, silver and bronze continued to 348. Philip II of Macedon conquered the Chalcidic peninsula and put Olynthus to ruins at that date. His coinage in gold, silver and bronze was influenced by the Chalcidic federal coinage

Full textAbstract:
Les plantes du genre Ficus entretiennent une relation de mutualisme avec des Chalcidiens pollinisateurs spécifiques Agaonidae, Hymenoptera). Cette relation est exploitée par des Chalcidiens parasites présentant des stratégies écologiques diverses (galligène, inquilins et parasitoïdes). Les relations Ficus-Chalcidiens comportent alors aussi bien des relations plantes-phytophages (Ficus-pollinisateurs, Ficus-galligènes) que des relations à multiples niveaux trophiques caractéristiques de communautés d’insectes parasites (Ficusgalligènes, galligènes-inquilins et parasitoïdes). Grâce à des marqueurs moléculaires, nous mettons en évidence les patrons divers de spéciation et de diversification dans trois cas d’études. En premier lieu, nous avons mis en évidence une différentiation génétique importante pour Ceratosolen fusciceps, le pollinisateur spécifique de Ficus racemosa, largement réparti de l’Inde jusqu’à l’Australie tropicale. Les différentiations sont très importantes entre différentes régions biogéographiques, suggérant l’existence de plusieurs espèce résultant de processus de spéciation allopatrique. En deuxième lieu, nous avons analysé la structuration génétique au sein d’un complexe d’espèces de Ficus sympatriques à statut taxonomique ambiguë, Ficus oligodon – Ficus auriculata – Ficus hainanensis. Nous mettons en évidene des traces d’hybridation et d’introgression locale et des histoires phylogéographiques probablement différentes, ce qui suggère une spéciation en cours, d’apparence sympatrique mais qui pourrait avoir été à l’origine allopatrique. Enfin, nous avons étudié la diversification dans deux genres africains de la famille Sycophaginae (une famille de Chalcidiens parasites présentant des stratégies écologiques diversifiées) en mettant en relation phylogénie moléculaire avec variations morphologiques. Ces trois cas d’étude montrent une large diversité de patrons de spéciation et de diversification dans les relations Ficus-Chalcidiens<br>Plants of genus Ficus are pollinated by specific pollinating chalcid wasps (Agaonidae, Hymenoptera). This mutualism is exploited by parasitic chalcid wasps presenting a variety of ecological strategies (gallers, inquilines and parasitoids). The Ficus-Chalcid wasp relationships thus comprise plant-phytophagous insect interactions (Ficus-pollinator, icusgaller) as well as complex interactions organized into hierarchical communities of parasitic insects (Ficus-gallers, gallers-inquilines and parasitoids). Using molecular markers, we illustrate a diversity of patterns of speciation and diversification in three study cases. First, we found substantial genetic differentiation between populations of Ceratosolen fusciceps, the specific pollinator of Ficus racemosa which is largely distributed from India to tropical Australia. The differentiation corresponds to biogeographic regions, suggesting the occurrence of more than one species that could have emerged through a process of allopatric speciation. Second, we shed light on the taxonomic status of the sympatric species complex of Ficus oligodon – Ficus auriculata – Ficus hainanensis by analysing the genetic differentiation between morphotypes. These species show traces of hybridisation and introgression, and present a complex phylogeographic history, suggesting an ongoing process of speciation that could have originated through allopatric differentiation despite coexistence in sympatry. Finally, we studied the diversification pattern in two African genera of the family Sycophaginae (a family of parasitic chalcid wasps presenting diverse ecological strategies) by plotting morphological variation on a molecular phylogeny. These three study cases show the diversity of speciation and diversification patterns in the Ficus-chalcid wasp interaction

Chacun des 750 figuiers presents dans le monde est pollinise specifiquement par un microhymenoptere chalcidien (chalcidoidea ; agaonidae ; agaoninae). A chaque ficus est egalement infeodee une faunule de chalcidiens non-pollinisateurs, generalement specifiques, qui peuvent etre galligenes, parasites ou inquilines. Nous avons centre notre etude sur les 14 especes mondiales du sous-genre sycomorus et sur les communautes de chalcidiens associes (ceratosolen pollinisateurs, apocrypta, platyneura et sycophaga galligenes). Nous avons voulu comprendre ce systeme d'un point de vue taxonomique, ecologique, evolutif et biogeographique. Notre travail a notamment permis de montrer que : 1- la famille des agaoniade sensu boucek, qui regroupe la majorite des chalcidiens infeodes a la ressource figue, n'est pas monophyletique : contrairement aux hypotheses en vigueur, les pollinisateurs forment un groupe monophyletique ancien, alors que les groupes de non-pollinisateurs ont colonise la ressource secondairement, et au cours de plusieurs evenements independants. 2- les corteges de non-pollinisateurs exercent sur le mutualisme ficus/pollinisateur des pressions de selection non-negligeables (impact negatif sur le pollinisateur, ainsi que sur les fonctions male et femelle de la plante-hote). Pressions qui ont pu jouer un role dans l'evolution de la dioecie dans le genre ficus. 3- le genre ceratosolen a connu une evolution vicariante entre la region malgache et l'afrique continentale, alors que les especes africaines et asiatiques ont de fortes affinites. La reconstruction de la phylogenie de ce groupe nous a permis de comprendre les cas d'exceptions a la regle un figuier - un pollinisateur. 4- les galligenes du genre apocrypta n'ont pas connu de cospeciation avec les pollinisateurs. Ce genre est d'origine recente, et a au contraire connu une radiation adaptative rapide sur la ressource. 5- les sycophaginae (platyneura et sycophaga) sont d'une anciennete comparable a celle des pollinisateurs, et ont connu une evolution biogeographique similaire. Leur diversification n'a cependant pas suivi celle des figuiers-hotes. Les adaptations a l'exploitation de la ressource sont apparues au moins deux fois independamment, et la capacite a penetrer la figue par l'ostiole n'est apparue qu'une fois.

Full textAbstract:
La connaissance de la diversité microbienne des milieux ultramafiques est essentielle pour établir le fonctionnement écologique de ces milieux, qui présentent de fortes teneurs en Ni et sont caractérisés par une flore particulière, e.g. plantes hyperaccumulatrices de Ni. La rhizosphère des hyperaccumulateurs comporte une forte proportion de bactéries résistantes au Ni, qui peuvent aussi agir sur la nutrition des plantes et sur les propriétés physico-chimiques du sol. Le premier défi de cette thèse a été de cerner le déterminisme de la diversité bactérienne de la rhizosphère d’hyperaccumulateurs de Ni. Le second a été de tester l'intérêt de souches PGPR (Plant Growth Promoting Rhizobacteria) pour optimiser l'agromine à partir d'interactions entre les rhizobactéries et les hyperaccumulateurs de Ni. La démarche s'est appuyée sur un ensemble de prospections dans deux régions climatiques et sur des analyses de séquençage haut débit. Des tests de cultures de plantes hyperaccumulatrices inoculées ont également été conduits. Les résultats montrent que le déterminisme de la diversité bactérienne est variable selon l'échelle spatiale. A l'échelle mondiale, le type de végétation est le facteur majeur structurant les communautés bactériennes, elle-même contrôlée indirectement par le climat. L’influence directe du climat (température et humidité) sur la diversité est significative mais moindre. A l'échelle d'une région climatique, la physico-chimie des sols ultramafiques structure et détermine la diversité des communautés bactériennes rhizosphériques. Enfin, l'inoculation de souches PGPR fortement bioaccumulatrices de Ni modifie la dynamique du Ni dans le sol, ce qui démontre qu'il existe une compétition pour le Ni entre la plante et la bactérie inoculée. En conclusion, le déterminisme de la diversité des communautés bactériennes rhizosphériques est dépendant de l'échelle spatiale considérée. En outre, le choix de la souche PGPR à inoculer, dans un contexte d'amélioration de l'agromine du Ni, est primordial<br>Knowledge of the microbial diversity in ultramafic areas is essential to establish the ecological functioning of these environments, which display high level of Ni and are characterized by the presence of particular plants, e.g. Ni hyperaccumulators. The rhizosphere of these plants promotes a high proportion of Ni resistant bacteria that can act on plant nutrition and soil physicochemical properties. The first challenge of this thesis was to understand the bacterial rhizosphere diversity of Ni hyperaccumulators. The second was to test the interest of PGPR (Plant Growth Promoting Rhizobacteria) strains in order to improve agromining based on rhizobacteria and Ni hyperaccumulators interactions. The approach was based on two-contrasted climatic areas prospection and on high-throughput sequencing analyzes. Tests on culture of hyperaccumulator plants inoculated were also conducted. The results show that the determinism of this bacterial diversity is variable according to the spatial scale. On a global scale, the vegetation type, indirectly influenced by the climate, is the major factor structuring bacterial communities. The direct influence of the climate (temperature and humidity) on bacterial diversity is significant but lower. At the scale of a climatic region, the physic-chemistry of ultramafic soils structures and determines the rhizosphere bacterial community diversity. Finally, the inoculation of highly Ni bioaccumulative PGPR strains modifies the Ni dynamic in the soil, demonstrating that there is a competition for this metal between the inoculated bacteria and the hyperaccumulator plant. In conclusion, the rhizosphere bacterial community diversity is dependent on the considered spatial scale. Furthermore, these results emphasize how the choice of the PGPR strain to inoculate is important in order to improve Ni agromining

Full textAbstract:
Dans l’Antiquité tardive, les théories de Platon et d’Aristote traitant du déplacement de la lumière (solaire ou oculaire) forment la base du discours sur la vision. L’approche néoplatonicienne des commentateurs grecs d’Aristote, influencée par la géométrie et la physiologie, est transmise à l’Occident latin, plus marqué cependant par le Timée de Platon – accessible en traduction, contrairement à l’oeuvre d’Aristote. Pour expliquer la formation de l’image dans l’âme de l’observateur, le monde grec combine des éléments issus d’Aristote et de Galien. L’Occident centre sa réflexion sur l’intériorité du sujet : la théorie augustinienne des trois visions élargit la théorie visuelle jusqu'à en faire une théorie de la pensée. Elle est ensuite redéfinie au XIIe siècle sous l’influence de la classification boécienne des puissances de l’âme. La propagation de la lumière est un élément essentiel de la vision. À partir de la métaphore du Dieu-lumière, les Pères grecs développent un discours métaphysique marqué par la physique aristotélicienne. Jean Scot Érigène le transmet au monde latin, où il vient conforter la théorie augustinienne de la vision. Au XIIe siècle, l'étude du Timée permet de transformer cette métaphysique en une optique physique originale. Alors qu’en grec les continuités avec le vocabulaire antique dominent, un lexique latin spécialisé semble se constituer, en partie sous influence grecque et en partie grâce à une réflexion autonome. Ce lexique, témoin de l’importance de la réflexion sur l’optique dans le monde latin durant le haut Moyen Age, est ensuite repris dans les traductions du XIIe siècle qui renouvellent la connaissance de cette discipline en Occident<br>During the late Antiquity, the theories of Plato and Aristotle about the solar or ocular light's movements are the basis of the theory of vision. The neoplatonic approach of the greek commentators to Aristotle, influenced by geometry and physiology, has been passed on to the Latin Occident, which was actually closer to Platon's Timaeus – available in traduction, unlike Aristotle's workIn order to explain the formation of the image in the observer's soul, the Greeks combine elements of Aristotle and Galen. The Occident focuses on the subject's interiority: the Augustinian theory enlarge the visual theory to create a thought's one. Then it's redefined during the twelth century under the influence of Boece's classification of the soul's forces. The propagation of light is a crucial element of vision. From the God-light's metapher, the Greek fathers developp a metaphysical speech influenced by Aristotle's physic. John Scotus Eriugena passes it on to the Latin world, where it comforts the Augustinian theory of vision. During the twelth century, this metaphysics changes to physics (optics) by means of the Timaeus' studies. Whereas in greek there is a continuity with the antique vocabulary, a specialised lexicon tends to appear in latin, through the greek and an autonomous thought, respectively. This lexicon, testimonial of the powerfull reflexion on optic during the early Middle Ages, is used in the twelth century's translations, which renew the knowing of this discipline in Occident

La tesi riguarda la Seconda Lega ateniese, di cui si studia il periodo, solitamente trascurato, compreso tra la fine della Guerra Sociale (355/4 a.C.) e la sconfitta di Atene a Cheronea (338 a.C.). Fonti principali, come del resto per il periodo precedente, sono le iscrizioni. Vengono quindi analizzate, in ordine geografico e cronologico, diciassette epigrafi di interesse storico (per lo più iscrizioni onorarie e trattati), considerate utili nella ricostruzione delle modalità di intervento ateniese all’interno della Lega. Area geografica privilegiata è la Grecia settentrionale, più immediatamente a contatto con l’espansionismo macedone. Obiettivo della tesi è infatti chiarire se la storia della Lega navale, più che una progressiva perdita di significato, non metta in evidenza un costante e coerente riorientamento degli obiettivi, stimolata dal confronto con Filippo II di Macedonia.<br>The topic of this thesis is the Second Athenian League during its final, usually underrated period, namely between the end of the Social War (355/4 B.C.) and the Athenian defeat at Chaeronea (338 B.C.). The sources for the history of the League both before and after the Social War are mainly epigraphical. Accordingly, seventeen historical inscriptions are carefully examined and thoroughly commented on: these are mostly honorific decrees and treaties, all of which proved to be useful to investigate how Athens acted within its League. The study, focusing on Northern Greece as the latter became more and more endangered by the growing power of Macedon, tries to ascertain whether the history of the Second Athenian League, far from becoming meaningless, might show a steady and consistent reorientation of its tasks, in and because of the military confrontation with Philip II.

Full textAbstract:
This chapter introduces Greek philosopher Aristotle, who was born in 384 B.C. in Stagira, a town on the peninsular of Chalcidice in the northern Aegean. It looks at Aristotle's extant works and early writings in the dialogue form, which were the product of his years in the Academy that may have a Platonic outlook. It also explains how Aristotle's dialogues were ranked alongside Plato's own in terms of their literary qualities. The chapter focuses on the first two books of On the Heavens (De Caelo), which examines matters of importance to his cosmology regarding the generation and destruction of the terrestrial elements and weight and lightness. It explains how Book I and Book II contain discussions of relevance to Aristotle's conception of the natural movements of the elements.
