Ulises es Sapo y es Topo : Rastros de Odisea en El viento en los sauces

La figura del retorno del héroe se ha repetido en la literatura durante siglos. La de un héroe en particular, Odiseo, también. Es así que en El viento en los sauces (The Wind in the Willows, 1908), la canónica novela de Kenneth Grahame, no es difícil encontrar similitudes, acercamientos, referencias o alusiones a Odisea. Desde el título del último capítulo "El retorno de Ulises" hasta sus personajes principales y las situaciones que experimentan, todo nos retrotrae a ese viaje al hogar que realiza el héroe que vuelve de la Guerra de Troya. Hay viaje, hay dificultades para continuarlo, hay peripecia, hay nostalgia, hay usurpadores del hogar que deben ser expulsados, hay regreso al fin, y hay gloria. Sin embargo, el escenario y el tiempo no son los mismos: ya no es el Mediterráneo clásico y sus islas, ni la Itaca ansiada, sino el Río y sus orillas, el "Bosque salvaje" y el "Ancho mundo", que se definen en un paisaje rural puramente inglés y de su época -el reinado de Eduardo VII, con su especial culto a la niñez, la nostalgia de la vida victoriana y las ansiedades causadas por los avances tecnológicos-. En el presente trabajo veremos que el protagonista tampoco es el mismo, sino que está partido en dos claros polos opuestos (aquí representados por el Topo y el Sapo), que hacían más humano al personaje homérico, al estar unificados, y en la novela que nos convoca comparten su amistad como dos entes independientes en la vida disipada de la campiña.

Pollen records from Bol'shoy Lyakhovsky Island, Siberia

Cryolithological, ground ice and fossil bioindicator (pollen, diatoms, plant macrofossils, rhizopods, insects, mammal bones) records from Bol'shoy Lyakhovsky Island permafrost sequences (73°20'N, 141°30'E) document the environmental history in the region for the past c. 115 kyr. Vegetation similar to modern subarctic tundra communities prevailed during the Eemian/Early Weichselian transition with a climate warmer than the present. Sparse tundra-like vegetation and harsher climate conditions were predominant during the Early Weichselian. The Middle Weichselian deposits contain peat and peaty soil horizons with bioindicators documenting climate amelioration. Although dwarf willows grew in more protected places, tundra and steppe vegetation prevailed. Climate conditions became colder and drier c. 30 kyr BP. No sediments dated between c. 28.5 and 12.05 14C kyr BP were found, which may reflect active erosion during that time. Herb and shrubby vegetation were predominant 11.6-11.3 14C kyr BP. Summer temperatures were c. 4 °C higher than today. Typical arctic environments prevailed around 10.5 14C kyr BP. Shrub alder and dwarf birch tundra were predominant between c. 9 and 7.6 kyr BP. Reconstructed summer temperatures were at least 4 °C higher than present. However, insect remains reflect that steppe-like habitats existed until c. 8 kyr BP. After 7.6 kyr BP, shrubs gradually disappeared and the vegetation cover became similar to that of modern tundra. Pollen and beetles indicate a severe arctic environment c. 3.7 kyr BP. However, Betula nana, absent on the island today, was still present. Together with our previous study on Bol'shoy Lyakhovsky Island covering the period between about 200 and 115 kyr, a comprehensive terrestrial palaeoenvironmental data set from this area in western Beringia is now available for the past two glacial-interglacial cycles.
