Andrienne Pauline Macaire (1796-1855): una artista en los márgenes

Durante el siglo XIX diversos artistas europeos emprendieron el viaje hacia diferentes puntos del continente americano. Entre ellos, mucho se dedicaron a la litografía, logrando en ciertos casos un amplio éxito comercial. Este artículo examina la trayectoria de la artista ginebrina Andrienne Pauline Macaire (1796-1855), dueña junto a su esposo de un temprano emprendimiento litográfico en la ciudad de Buenos Aires. Macaire puede ser considerada la primera artista profesional de renombre activa en esa ciudad. En efecto, es posible diferenciar su trayectoria de las de otras artistas contemporáneas, de las cuales se dispone de menos información y de las que han sobrevivido menos obras. En una primera parte del texto se analiza su inscripción en la literatura artística nacional. A continuación, se describe su formación en Ginebra y se estudia su importante actividad en Buenos Aires, estableciendo conexiones con el panorama artístico local. A lo largo del artículo se presentan obras y fuentes inéditas, o insuficientemente exploradas, a fin de justipreciar su carrera artística y de brindar elementos para futuras investigaciones.

Polifemo en Yucatán. Variaciones sobre un episodio de la Eneida en la épica cortesiana del Quinientos

Entre los modelos literarios que, en las epopeyas quinientistas acerca de la conquista de México, sirven para dar forma épica a la materia histórica tomada de las crónicas, la Eneida de Virgilio desempeña un papel fundamental. En el presente artículo se pretende mostrar cómo la identificación de Jerónimo de Aguilar con el Aqueménides virgiliano, que se encuentra por primera vez en el Carlo famoso de Luis Zapata, reaparece en Francisco de Terrazas, en Gabriel Lobo Lasso de la Vega y en Antonio de Saavedra Guzmán, así como proponer algunas consideraciones acerca de las relaciones que se hayan podido dar entre las obras de estos poetas.

The Devil and Views on the “Other” in Part One of Pedro Cieza de León’s "Crónica del Perú" (1553)

Many 16th century Spanish chroniclers and missionaries, arriving at what they interpreted as a New World, saw the Devil as a “hermeneutic wildcard” that allowed them to comprehend indigenous religions. Pedro Cieza de León, a soldier in the conquest of Peru, is a case in point. Cieza considers the Devil responsible for the most aberrant religious practices and customs of the Indians, although he views the natives in a positive light, as men susceptible to divine salvation. From a providentialist perspective of the history of the conquest, Cieza interprets that the evangelization and conversion of the Indians and the implantation of Christian civilization by the Spanish Crown, were able to defeat the Devil.

The Techialoyan Codices and their Number

In this article, it is proposed a brief revision of the number of Techialoyan codices. To do this, the text starts with a definition of the corpus, that it is composed of manuscripts done between the half of the 17th century and beginning of the next. Around these documents there are many doubts and it remains much to do. In this case, we present a review around the lists and catalogues to see the changes of the group through time. Our conclusion is that is necessary recount the corpus, because there are fragmented documents and others are unknowns or copies. Finally, we show our count, that leaves the number less than fifty-six documents catalogued until today.

De la Teoría Institucional del Arte a la Curaduría Creativa: revisión de una aproximación institucional a la definición de lo "artístico"

Es una revisión e interpretación profunda de la Teoría Institucional de Arte cuya reflexión se extiende hasta la Curaduría Creativa, un fenómeno del arte contemporáneo, del que podría predicarse un estatus de obra de arte. El objetivo principal pretende defender las condiciones bajo las cuales la curaduría puede considerarse una obra de arte.

Anatomical studies of the flower, fruit and seeds of Myrceugenia rufa (Myrtaceae)

Myceugenia rufa is a rare and endemic species from the coast of central Chile. There are no published studies describing flower, fruit or seed anatomy. Forty-two accessions were collected from across the geographic range of the species. Reproductive structures were fixed, dehydrated, embedded in paraffin, sectioned and stained with Safranin O and Fast green. Anatomy of floral buds, mature flowers, fruits and seeds was described. Reproductive anatomy matches that of other Myrtaceae, such as presence of druses, internal phloem and schizogenous secretory cavities in buds, flowers, fruits and seeds. The anatomy and development of reproductive structures of M. rufa might enhance the understanding for future studies regarding natural reproduction and conservation programs.

From Gods to men: A historical overview of the discovery of the chemical elements

To achieve the apparently simple Periodic Table of the Elements has implied tremendous efforts over thousands of years. In this paper we present a brief history of the discovery of the chemical elements from prehistory to the present day, revealing the controversies that arose on the way and claiming the important work performed by alchemists in the advancement of knowledge. This is especially important if we consider that alchemy had a period of existence of many thousands of years, while the "Chemistry", officially established as a science in the eighteenth century, has operated as such for only a few hundred years. Even so, if we consider the progress of discovery and isolation of chemical elements throughout history, it can be observed that the number of elements identified is achieved mainly in the nineteenth and twentieth centuries, reflecting the development of instrumental techniques, that facilitated this task.

Geochemical characterization of the fire-fountain fed deposits of Las Herrerias volcano (Campo de Calatrava Volcanic Field, Ciudad Real)

The Las Herrerias volcano (Bolanos de Calatrava, Campo de Calatrava Volcanic Field) is characterized by the great amount and variety of fire-fountain fed deposits. All these deposits are compositionally similar, being constituted by magnesium-rich (MgO = 11.58-4.19%), aluminium-poor (Al2O3 = 9.64-10.99%) highly sodic (Na2O = 2.24-3.81%) melanephelinites, with high contents in rare earth-elements (10x-200x chondrite), particularly in light-rare earth elements with respect to the heavy ones [(La/Lu)(N) = 32-35]. Contrary to the equivalent melanephelinites of this volcanic field, the relatively low contents in Ni (233-286 ppm), Cr (393-520 ppm) and magnesium number (Mg* = 45-54) indicate that these rocks do not correspond with primary melts. On the other hand, the variable distribution of clinopyroxene in the magma during eruption would be responsible for the slight compositional differences observed in the studied samples. Finally, we argue that these fire fountains were developed in a continental intraplate setting.

Palaeoenvironmental analysis based on alluvial ostracod assemblages of the Cenicero section (lower Miocene, NW Ebro Basin)

In this work we perform for the first time a palaeoenvironmental and biostratigraphic analysis of the lower Miocene alluvial deposits of the Cenicero section (NW sector of the Ebro Basin; N Iberian Peninsula), based on the ostracod and micromammal assemblages. One of the main characteristics of this section is the unusual abundance on non-reworked ostracods present in the studied samples compared to other European sequences of similar age and sedimentary environment. This fact has allowed us to develop precise palaeoenvironmental reconstructions. The variations of the identified ostracod assemblages, defined by species such as Cyclocypris laevis, Ilyocypris bradyi, Ilyocypris gibba, Limnocythere sp. or Pseudocandona parallela, record the development of small, ephemeral and shallow ponds in a distal alluvial and/or floodplain environment. Towards the upper part of the section the ponds appear to be less ephemeral, being the aquatic systems more stable for ostracods development. Variations in the water temperature and salinity have been observed along the section, which are related to changes in the local pluviometric regime. On the other hand, the presence of micromammals in one of the studied samples has allowed the precise dating of this section. Thus, the presence of Armantomys daamsi dates the Cenicero section as Agenian (lower Miocene), local zone Y2 (MN2).
