Nel segno di Zeus: su alcuni louteria fittili da Akragas
No full textThe study considers some louteria from Agrigento (from the Sanctuary of Zeus Olympios and the so-called Sanctuary of chthonic deities), dated from the sixth to the fifth century BC. In particular we propose a reading of the images that decorate these basins in relation to the sacred contexts in which they were used, paying particular attention to a series of louteria with running quadrigae and winged figures and an example depicting the transport of Achilles’ weapons by the Nereids. Thus symbolic imagerie which refers to the rituals and cults practised in these sacred spaces is reconstructed
Dioscuri spartani, Dioscuri beotici: alcune testimonianze iconografiche
No full textThe paper discusses an iconographic type recorded on a series of pinakes from the Mannella sanctuary at Locri Epizephyrii portraying two young horsemen (one has a lyra, the other a kantharos) in front of a female figure. This is thought to be the variant of a more common type representing the Spartan Dioskouroi with a shield and phiale. The attributes of the horsemen (kantharos and lyra), unusual for the Tyndaridai, have been interpreted as a reference to the educational value of music and symposia relating to the male element within the context of wedding rituals held in the sanctuary. The lyra, however, may not be a simple element to enrich the meaning of the image, but rather an attribute aimed at clarifying the identity of the two characters, which we propose interpreting as Amphion and Zethus, the so-called Theban Dioskouroi
Il cratere del Pittore dei Niobidi al Museo Archeologico di Agrigento: dalla Gela post-tirannica alla Sicilia post-unitaria
No full textThe paper considers the monumental crater of the Niobid Painter found in Gela in 1889 and preserved in the Archaeological Museum of Agrigento. It depicts an Amazonomachy all round its body, the myth of Herakles and Pholos along with a Centauromachy on the two sides of its neck. The first part of the contribution traces the history of the vase from its discovery to the musealization; the symbolical meaning taken up by this object and this type of precious vases in the post-united Sicily is reconstructed. In the second part of the paper, the crater (a cinerarium) with its images are analyzed in their ancient context of use. This study is an attempt to reconstruct the physiognomy of the Geloan buried in this prestigious urn, through the associations of meaning underlying the figuration. The profile of a character belonging to the jeunesse dorée of the post tyranny Gela emerges. This character tells about his heroic and otherworldly expectations while appropriating the mythical Athenian models and entrusting his identity and, perhaps, the identity of the group or ‘clan’ to which he must have belonged, to the images depicted on the crater
The Gribov phenomenon in flat and curved spaces
No full textThe quantization of Yang-Mills theories relies on the gauge-fixing procedure. However, in the non-Abelian case this procedure leads to the well-known Gribov ambiguity. In order to solve the ambiguity a modification of the functional integral formula must be introduced. As a consequence of this, the Green functions get deep modifications in the infrared. We consider, in particular, the SU(N) case and show that in the pure gauge case the ghost propagator is enhanced, while the gluon propagator is suppressed in this limit, therefore the study of the Gribov ambiguity may shed some light on the mass gap problem and on color confinement. We discuss some recent developments on the subject in the case of a curved background. We argue that the concurrent presence of a spacetime curvature and the Gribov ambiguity may introduce further modifications to the Green functions in the infrared. © World Scientific Publishing Company

Limiting curvature mimetic gravity for group field theory condensates
No full textNonsingular bouncing cosmologies are realized in limiting curvature mimetic gravity by means of a multivalued potential f(□φ) depending on the d'Alembertian of a scalar field φ. We determine the functional form of such a potential so as to exactly reproduce the cosmological background dynamics obtained in the group field theory approach to quantum gravity. The original proposal made by Chamseddine and Mukhanov [J. Cosmol. Astropart. Phys. 03 (2017) 009JCAPBP1475-751610.1088/1475-7516/2017/03/009], which was shown to lead to a background dynamics reproducing the effective dynamics of loop quantum cosmology, is here recovered as a particular case for some specific choices of the parameters of our model. We also clarify some issues related to the multivaluedness of the function f, showing in particular that its functional form can be unambiguously reconstructed by imposing appropriate matching conditions at the branching points
Paradigmi mitici, cifre simboliche e rituale funerario: su alcuni crateri figurati dalle necropoli greche di Sicilia
No full textIl contributo prende in considerazione i crateri-cinerari figurati restituiti dalle necropoli greche di Sicilia, ricollegati, in via di ipotesi, a credenze escatologiche connesse alla sfera del culto dionisiaco, cercando di rintracciare l’origine e di inquadrare l’affermarsi di tale rito in Sicilia, e di delineare gli attori di questo rituale, con il quale l’identità del/della defunto/a era richiamata dalla forma del cinerario e dalle immagini che lo decoravano.
L’analisi prende avvio dai cinerari con raffinate e complesse scene mitiche dell’Agrigento dell’età della tirannide emmenide per arrivare ai crateri della Lipara del IV secolo, che esprimono attraverso narrazioni più esplicite l’auspicio (o la certezza) di un accesso a una dimensione salvifica e di felicità eterna, di un accoglimento post mortem nel thiasos divino.
Si ricostruisce una pluralità di segni e mezzi espressivi variamente declinati che arricchisce di sfumature e articola il contesto socio-culturale di riferimento e il relativo panorama rituale nello spazio e nel tempo, pur in un comune sottofondo di credenze escatologiche, maturate e cresciute probabilmente nella Sicilia delle tirannidi, e sviluppatesi poi in maniera originale ma coerente nei singoli contesti, nei diversi tessuti sociali, nella trama delle differenti ritualità funerarie nel secolo successivo e oltre, quando il mito perderà a poco a poco la sua funzione legittimante e identitaria, soppiantato da narrazioni più dichiaratamente misteriche e iniziatiche.The contribution takes into consideration the figured cinerary craters returned from the Greek necropolises of Sicily, linked, by way of hypothesis, to eschatological beliefs connected to the sphere of the Dionysian cult, trying to trace the origin and to frame the affirmation of this rite in Sicily, and to outline the actors of this ritual, with which the identity of the deceased was recalled by the shape of the cinerary and by the images that decorated it.
The analysis starts from the cineraries with refined and complex mythical scenes of Agrigento from the age of the emmenid tyranny to arrive at the craters of Lipara of the fourth century, which express through more explicit narratives the hope (or the certainty) of access to a saving dimension and eternal happiness, of a post mortem acceptance in the divine thiasos.
A plurality of variously declined signs and expressive means is reconstructed that enriches with nuances and articulates the socio-cultural context of reference and the relative ritual panorama in space and time, albeit in a common background of eschatological beliefs, probably matured and grown in Sicily tyrannies, and then developed in an original but coherent way in the individual contexts, in the different social tissues, in the plot of the different funeral rituals in the following century and beyond, when the myth gradually loses its legitimizing and identity function, supplanted by narratives more openly mysterious and initiatory

Su alcuni vasi fuori serie della Collezione Panitteri
No full textIl contributo riesamina tre vasi attici rinvenuti ad Agrigento, già appartenuti alla collezione Panitteri e oggi a Monaco, che si segnalano per l’originalità e la rarità dei temi iconografici, oltre che per il pregio della forma: lo psykter del Pittore di Pan (480-470 a.C.), il vaso kalathoide del Pittore di Brygos (480-470 a.C.) e il cratere a volute del Pittore di Geras (490-480 a.C.). Si tratta, almeno in due dei tre casi, di vasi-cinerari che si legano ad un rituale sviluppatosi, se non nato, in seno alla tirannide emmenide e all’affermarsi all’interno della corte teroniana di credenze escatologiche connesse alla sfera del culto dionisiaco. L’uso ad Akragas, proprio tra il primo e il secondo quarto del V sec. a.C., di preziosi cinerari attici, decorati con complesse scene mitiche sapientemente sviluppate sulla superficie del vaso, ricorda il ruolo fondamentale del mito nell’Akragas dei tiranni, ai cui circoli colti e al cui entourage dobbiamo immaginare che si legassero tali tipi di elitarie sepolture come pure la pratica di raffinati simposi “fuori norma” con l’utilizzo di tali preziosi vasi. Emerge in particolare una fitta trama di intrecci tra imagerie e poesia lirica legata ad una élite colta, che ora raffina, grazie anche ai poeti di corte, il suo modo di autorappresentarsi attraverso l’immaginario mitico
Il mondo muliebre. Scene al femminile sui vasi figurati
No full textIl saggio esamina alcune ceramiche figurate di importazione e di produzione locale comprese in corredi sepolcrale della necropoli punica lilibetana ed esposte al Museo Archeologico Regionale di Marsala. Di tali vasi si illustrano i temi figurativi legati al mondo femminile cercando di definire i contorni dell'ambiente di produzione di tali vasi e della "committenza".The paper examines some imported and locally produced figurative ceramics included in grave goods from the Punic necropolis of Lilybaeum and exhibited at the Regional Archaeological Museum of Marsala. The figurative themes of the vases, linked to the female world, are illustrated, attempting to define the contours of the production environment of these vases and the ‘patronage’
