The Maya wall paintings from Chajul, Guatemala
2020
The recent renovation of a house in Chajul in western Guatemala has revealed an unparalleled set of wall paintings, most probably from the Colonial period (AD 1524–1821). The iconography of the murals combines pre-Columbian elements with imported European components in a domestic rather than a religious setting, making them a unique example of Colonial-period art. Here, the authors present the results of iconographic, chemical and radiocarbon analyses of the Chajul house paintings. Dating to the seventeenth to eighteenth centuries AD, the paintings may be connected to a revival of the local religious organisation (cofradías) in the context of waning Spanish colonial control.
Climbing into the past—first Himalayan mummies discovered in Nepal
2003
In a cave system in Mebrak (Mustang District, Western Nepal), a team of archaeologists investigating extensive abandoned settlements in the high Himalayas made an extraordinary discovery in 1995. One of the caves had been used as a community burial chamber from ca. 400 BC to 50 AD. Inside, approximately 30 naturally mummified bodies rested in bed-like wooden coffins exhibiting ornamental carving and elaborate painting. The dead had been furnished with a rich store of grave goods consisting of both personal ornaments and objects of daily life as well as the remains of domestic animals. Due to the favourable climatic conditions, all of the artefacts, which also include fur and textile garment…
Cocina cave revisited: Bayesian radiocarbon chronology for the last hunter-gatherers and first farmers in Eastern Iberia
2018
Abstract Recent excavations and radiocarbon work conducted at Cocina Cave (Valencia region, Eastern Iberia) provide new insights into the transition from foraging to farming in the eastern Iberian Peninsula between 8000 and 7300 cal yrs. BP. Cocina cave was discovered in 1940 and excavated by L. Pericot from 1941 to 1945. J. Fortea continued excavations in the 70s. Despite early international recognition and great promise of significance, the materials recovered from these excavations have only been partially analyzed and published. A new project started in 2012 is focused on these cave deposits with the main goal of understanding the occupation sequence during the neolithization process in…
Evolution of the human chromosome 13 synteny: Evolutionary rearrangements, plasticity, human disease genes and cancer breakpoints
2020
The history of each human chromosome can be studied through comparative cytogenetic approaches in mammals which permit the identification of human chromosomal homologies and rearrangements between species. Comparative banding, chromosome painting, Bacterial Artificial Chromosome (BAC) mapping and genome data permit researchers to formulate hypotheses about ancestral chromosome forms. Human chromosome 13 has been previously shown to be conserved as a single syntenic element in the Ancestral Primate Karyotype
Neotropical primate evolution and phylogenetic reconstruction using chromosomal data
2017
Platyrrhini are a group of Neotropical primates living in central and south America, and have been extensively studied through morphological and molecular data in order to shed light on their phylogeny and evolution. Agreement on the main clades of Neotropical primates has been reached using different approaches, but many phylogenetic nodes remain under discussion. Contrasting hypotheses have been proposed, presumably due to different markers and the presence of polymorphisms in the features considered; furthermore, neither Neotropical primate biodiversity nor their taxonomy are entirely known. In our perspective, a cytogenetic approach can help by making an important contribution to the ev…
Biofilm biodiversity in French and Swiss show caves using the metabarcoding approach: First data.
2018
International audience; In recent decades, show caves have begun to suffer from microorganism proliferation due to artificial lighting installations for touristic activity. In addition to the aesthetic problem, light encourages microorganisms that are responsible for physical and chemical degradation of limestone walls, speleothems and prehistoric paintings of cultural value. Microorganisms have previously been described by microscopy or culture-dependent methods, but data provided by new generation sequencing are rare. The authors identified, for the first time, microorganisms proliferating in one Swiss and in four French show caves using three different primers. The results showed that bo…
Early cave art and ancient DNA record the origin of European bison
2016
The two living species of bison (European and American) are among the few terrestrial megafauna to have survived the late Pleistocene extinctions. Despite the extensive bovid fossil record in Eurasia, the evolutionary history of the European bison (or wisent, Bison bonasus) before the Holocene (<11.7 thousand years ago (kya)) remains a mystery. We use complete ancient mitochondrial genomes and genome-wide nuclear DNA surveys to reveal that the wisent is the product of hybridization between the extinct steppe bison (Bison priscus) and ancestors of modern cattle (aurochs, Bos primigenius) before 120 kya, and contains up to 10% aurochs genomic ancestry. Although undetected within the fossil re…
Simplification Of Painting Images For Tactile Perception By Visually Impaired Persons
2018
The access to artworks by visually impaired people requires a simplified tactile representation of paintings. This paper presents the difficulties of direct transcription of artworks and the test results of simplification of the paintings done by Australian Aborigines which don't have purely visual elements such as shadows or perspective. The implemented methodology is bottom-up: it starts with tactile representation of basic elements relevant to the understanding of the whole painting, then their association into more complex concepts. The context of associations is explained through audio-description. The results of the tests with visually impaired persons are analyzed and explained.
Materiality and atmosphere. Two American beat artists painting Europe
2019
The article discusses how European painting heavily influenced two American Beat painters in the post war years. Post-war American painting was often concerned with breaking away from traditional iconography and style, but Jay DeFeo and Joan Brown chose to engage with European traditional painting. Both artists travelled to Europe early in their careers and both declare an intense interest in European painters, paintings, and architecture. In Brown’s case particularly the works of Goya, Velazquez, and Rembrandt become scrutinized and remodeled in her pasty abstract style. De Feo, on her hand, states a particular interest in how the European cities’ distinct colors, lights and textures inspi…
Donald Friedman's Interviews : Writers as Visual Artists
2018
With Volume 39, “Gestures and their Traces” INTERFACES, now an on-line journal, began its third iteration. In volume 40, we welcome Donald Friedman, novelist, essayist, and preeminently the author of The Writer’s Brush, Paintings, Drawings, and Sculpture by Writers, as a regular contributor to the journal. In the process of researching The Writer’s Brush, he video interviewed a number of contemporary writers; he is editing these tapes and these will begin a new feature of the journal. The fir...
