DAVID STUART

Una historia monumental de la civilización maya a lo largo de tres milenios.Durante siglos, la civilización maya permaneció oculta tras las ciudades en ruinas devoradas por la selva tropical. Gracias a los descubrimientos arqueologicos mas recientes, al fin podemos contar la historia desde su perspectiva.En Los cuatro cielos, el reconocido historiador y arqueologo David Stuart revela que no hubo un unico auge y caida de los mayas, sino una serie de nacimientos y colapsos a lo largo de casi tres milenios. A partir del desciframiento de sus jeroglificos narra la aparicion de los primeros asentamientos permanentes, caracterizados por su arquitectura monumental y un urbanismo floreciente, que marcaron el inicio del periodo Clasico a mediados del siglo II d. C. Nos descubre un mundo de majestuosas cortes reales estrechamente ligadas por matrimonios, alianzas cambiantes y guerras. Tambien analiza con detenimiento las grandes dinastias Kanul y Mutul, cuya rivalidad marco el destino de los reinos circundantes dando lugar a la Gran Ruptura del siglo IX, momento en el que las ciudades fueron abandonadas en medio de conflictos internos, tensiones sociales y cambios ambientales.Con una prosa accesible y numerosas ilustraciones, Los cuatro cielos hace un retrato de la civilizacion maya como una constelacion de reinos interconectados, siempre en movimiento, que nacen, se enfrentan, caen y se reinventan a lo largo de los siglos.

lo largo del tiempo el hombre ha buscado plantas por todo el mundo con fines diversos: curar enfermedades, aliviar la mente, suscitar amor, provocar sueños curiosos... El jardinero y botánico David C. Stuart cuenta la historia de esa larga e inquietante busqueda, y de como el mundo de las plantas y el humano se han influido reciprocamente.Pero esta no es solo una historia de balsamos calmantes y curas heroicas; muchas plantas tienen un lado oscuro que equilibra la luz. La mayoria de las que configuran este jardin de la tentacion son poderosas y sus efectos son de doble filo, tanto pueden sanar o aliviar como matar o esclavizar al hombre.Stuart narra asi numerosas historias asombrosas de como el hombre ha ido cayendo a lo largo del tiempo en un mundo de tentaciones: poder, seduccion, dinero... En efecto la busqueda de nuevas plantas ha provocado guerras, contribuido a establecer rutas comerciales internacionales pero tambien ha engendrado fortunas y nuevos amores.

Ogden Nash was a rare poet. He celebrated the ordinary with delight and curiosity: husbands and wives at work, children at play, a society in motion. He studied popular culture with a penetrating eye and wrote about America, its icons, habits, and affectations with humor and levity. He struggled with comparisons to serious poets, those heroes of the canon who abandoned the rhyme and meter that Nash found crucial to his style of writing. His witty, insightful, and graceful vignettes captured those moments in life that defy heavy-handed treatment. Nash did not live out the stereotype of the aloof poet-recluse. In addition to his writing, Nash pursued publishing, screenwriting, and a rigorous lecture circuit. This self-styled [pet of wide appeal appeared in newspapers and magazines found in homes across the country, accessible publications such as Life, New Yorker, Cosmopolitan, SportsIllustrated, ReadersDigest, and McCalls. At a time when childrens literature meant Winnie-the-Pooh, Nash produced verses for and about young people that amused, educated, and more importantly, didnt pander or lecture. These poems and collections, including Custard the Dragon, The New Nutcracker Suite and Other Innocent Verses, A Boy Is a Boy, and Girls Are Silly, were classics of the genre. Nash left behind an invaluable body of work: charming, clever, and utterly unique.

The worlds foremost expert on Maya culture looks at 2012 hysteria and explains the truth about what the Maya meant and what we want to believe.Apocalypse 2012: An Investigation into Civilizations End. The World Cataclysm in 2012. 2012: The return of Quetzalcoatl. According to many of these alarmingly titled books, the ancient Maya not only had a keen insight into the mystical workings of our planet and the cosmos, but they were also able to predict that the world will end in the year 2012.David Stuart, the foremost scholar of the Maya and recipient of numerous awards for his work, takes a hard look at the frenzy over 2012 and offers a fascination (and accurate) trip through Mayan culture and belief. Stuart shows how the idea that the "end of the Mayan calendar," which supposedly heralds the end of our own existence, says far more about our culture than about the ancient Maya. The Order of Days explores how the real intellectual achievement of ancient Maya timekeeping and worldview is far more impressive and remarkable than any of the popular, and often outrageous, claims about this advanced civilization.As someone who has studied the Maya for nearly all of his life and who specializes in reading their ancient texts, Stuart sees the 2012 hubbub as the most recent in a long chain of related ideas about Mesoamericans, the Maya in particular, that depicts them as somehow oddball, not "of this world," or as having some strong mystical link to other realms.Because the year 2012 has no prominent role in anything the ancient Maya ever actually wrote, Stuart takes a wider look at the Maya concepts of time and their underlying philosophy as we can best understand them. The ancient Maya, Stuart contends, were worthy of study and admiration not because they were strange but because they were altogether human, and they developed a compelling vision of time unlike any other civilization before or since.
