El episodio del encuentro entre Eneas y la Sibila de Cumas en Metamorfosis 14.102157 forma parte de la "Eneida ovidiana", aquella sección del poema (13.62314.608) en la cual se narran las aventuras de Eneas desde su partida de Troya hasta su asentamiento definitivo en el suelo itálico. En este trabajo proponemos un análisis del pasaje teniendo en cuenta aquellos rasgos que permiten estudiarlo en relación con las demás historias de amor del poema. Emplearemos para ello las categorías de "repetición", "continuidad narrativa" y "cierre" enunciadas por S. Wheeler en Narrative Dynamics in Ovid's Metamorphoses (2000).

El discurso de la nodriza de los vv. 1-45, en el prólogo de Medea de Eurípides, establece un punto de partida indispensable para la comprensión de la tragedia. Intentaremos analizar las dos partes del discurso en la vinculación que se establece entre la presentación del personaje de Medea y su relación con el sentido de la tragedia, que no intenta condenar la pasión como fuente de catástrofe, ni mostrar el triunfo de la pasión sobre la reflexión, con los grandes males que acarrea, sino destacar la humanidad primigenia del personaje.

En la década del treinta, el catolicismo se instala fuertemente en Latinoamérica bajo la consigna de "recristianizar" la sociedad. En el caso argentino, Leopoldo Marechal realiza un camino que, guiado por crisis espirituales, lo lleva a abandonar los fundamentos vanguardistas para lanzarse a la búsqueda de la belleza, la armonía y el orden, aunando fe y estética en su escritura poética. En este contexto, Laberinto de amor de 1936, al inscribirse anacrónicamente dentro de la tradición cristiano-medieval, moldea un poeta que, como émulo del Creador divino, liga el presente con la eternidad, postulando la necesidad de forjar una comunidad de amor y entrega hacia el otro

High-resolution records of opal, carbonate, and terrigenous fluxes have been obtained from a high-sedimentation rate core (MD84-527: 43°50'S; 51°19'E; 3269 m) by normalization to 230Th. This method estimates paleofluxes to the seafloor on a point-by-point basis and distinguishes changes in sediment accumulation due to variations in vertical rain rates from those due to changes in syndepositional sediment redistribution by bottom currents. We also measured sediment delta15N to evaluate the changes in nitrate utilization in the overlying surface waters associated with paleoflux variations. Our results show that opal accumulation rates on the seafloor during the Holocene and stage 3, based on 14C dating, were respectively tenfold and fivefold higher than the vertical rain rates, At this particular location, changes in opal accumulation on the seafloor appear to be mainly controlled by sediment redistribution by bottom currents rather than variations in opal fluxes from the overlying water column. Correction for syndepositional sediment redistribution and the improved time resolution that can be achieved by normalization to 230Th disclose important variations in opal rain rates. We found relatively high but variable opal paleoflux during stage 3, with two maxima centered at 36 and 30 kyr B.P., low opal paleoflux during stage 2 and deglaciation and a pronounced maximum during the early Holocene, We interpret this record as reflecting variations in opal production rates associated with climate-induced latitudinal migration of the southern ocean frontal system. Sediments deposited during periods of high opal paleoflux also have high authigenic U concentrations, suggesting more reducing conditions in the sediment, and high Pa-231/Th-230 ratios, suggesting increased scavenging from the water column. Sediment delta15N is circa 1.5 per mil higher during isotopic stage 2 and deglaciation. The low opal rain rates recorded during that period appear to have been associated with increased nitrate depletion. This suggests that opal paleofluxes do not simply reflect latitudinal migration of the frontal system but also changes in the structure of the upper water column. Increased stratification during isotopic stage 2 and deglaciation could have been produced by a meltwater lid, leading to lower nitrate supply rates to surface waters.
