A Unique Collection of Palaeolithic Painted Portable Art: Characterization of Red and Yellow Pigments from the Parpalló Cave (Spain).
2016
In this work we analyze the pigments used in the decoration of red and yellow motifs present in the portable art of the Parpallo Cave (Gandia, Spain), one of the most important Palaeolithic sites in the Spanish Mediterranean region. Energy dispersive X-ray fluorescence spectrometry (EDXRF) and spectrophotometry in the visible region (CIEL*a*b*color coordinates and spectral reflectance curves) were used to perform in situ fast analyses of the red and yellow motifs with portable equipment and to characterize their elemental composition and their colorimetric perception, respectively. According to the elemental composition, the intensity of the fluorescence iron signals in red and yellow motif…
The Painted Silk Panels of Palazzo Barberini at Rome. The Scientific Investigation and Preservation Challenge
2013
Abstract This paper reports the study carried out on the 18th century painted silk panels that cover the walls of the so called Salotto delle sete dipinte in Palazzo Barberini at Rome on the occasion of the conservation work started in 2007. Microscope and spectroscopy investigations were performed in order to study the materials and the realization techniques of the painted silk panels and to evaluate the conservation conditions. Moreover ageing tests were performed in order to evaluate the stability of the consolidant/protective product used for the silk panels.
Archaeometrical Studies of Classic Mayan Mural Painting at Peten: La Blanca and Chilonche
2014
[EN] La Blanca and Chilonche are two of the many Mayan settlements located on the lower reaches of the Mopan river (Department of Petén, Guatemala). The archaeological work conducted by La Blanca Project (University of Valencia, Spain) over the last ten years has revealed the rich polychrome of the monumental architecture of these sites, where the remains of ancient mural paintings are of the highest quality. In order to ascertain the materials and techniques used by painters at each site throughout the Classic period, our research team has recently conducted an analytical study with a multi-technique approach based on the combination of several non destructive and micro-destructive instrum…
Identification of plant cells in black pigments of prehistoric Spanish Levantine rock art by means of a multi-analytical approach. A new method for s…
2017
We present a new multi-analytical approach to the characterization of black pigments in Spanish Levantine rock art. This new protocol seeks to identify the raw materials that were used, as well as reconstruct the different technical gestures and decision-making processes involved in the obtaining of these black pigments. For the first of these goals, the pictorial mat- ter of the black figurative motifs documented at the Les Dogues rock art shelter (Ares del Maestre, Castello ́ n, Spain) was characterized through the combination of physicochemical and archeobotanical analyses. During the first stage of our research protocol, in situ and non- destructive analyses were carried out by means of…
Nuevos datos documentales sobre Paolo Da San Leocadio
2013
Se presenta un documento que aclara la identidad de la que pudo o debió ser la segunda esposa del italiano Paolo da San Leocadio (Reggio Emilia 1447-Valencia 1520), precoz introductor en 1472 de la pintura del Renacimiento en España. Se trata del contrato matrimonial entre Jaume Llopis, cambista de Valencia, y el pintor, quienes acuerdan el enlace entre dicho pintor e Isabel Llopis, hermana de Jaume, que ofreció una importante dote. A document is presented here which clarifies the identity of who could have been or must have been the second wife of the Italian Paolo da San Leocadio (Reggio Emilia 1447-Valencia 1520), one of the first people to introduce Renaissance paintings to Spain in 147…
Un contrato inédito de Juan de Juanes. El retablo de la Cofradía de la Sangre de Cristo de Valencia (1539)
2012
This article is based on an unpublished contract signed in 1539 by Vicente and Juan Macip for an altarpiece for the Valencian Brotherhood of the Blood of Christ. The agreement stipulates that Juan, later known as Juan de Juanes, had to paint the scenes. Thus the document reinforces the hypothesis that Juan Macip was the most important painter in the Macip workshop during the 1530’s. It also fills a documental void in between the completion of the Silversmith’s Guild altarpiece (1534-1539) and the contract for the Fuente la Higuera altarpiece (1548). This study also verifies the popularity of the iconography of the seven sheddings of the Blood of Christ and processions of disciplinants.<b…
Un contrato de los Hernandos para la capilla de les Febres de la Seo de Xàtiva en 1511
2006
The contract dated 1511 signed by Fernando Llanos and Fernando Yáñez de la Almedina, Castillian painters known as “the Hernandos,” for the termination of an altarpiece in the chapel of the “Virgen de les Febres” is presented here. This chapel was founded in 1497 in the collegiate church of Jàtiva (Valencia) by Francisco de Borja, Bishop of Teano and Cardinal of Cosenza. Based on this document, a series of hypotheses are put forth concerning the trajectory and works of “the Hernandos” following their execution of the doors of the main altarpiece of the Cathedral of Valencia.<br><br>Se presenta el contrato firmado en 1511 por Fernando Llanos y Fernando Yañez de la Almedina, pintor…

Non-linear Local Polynomial Regression Multiresolution Methods Using $$\ell ^1$$-norm Minimization with Application to Signal Processing
2015
Harten’s Multiresolution has been developed and used for different applications such as fast algorithms for solving linear equations or compression, denoising and inpainting signals. These schemes are based on two principal operators: decimation and prediction. The goal of this paper is to construct an accurate prediction operator that approximates the real values of the signal by a polynomial and estimates the error using \(\ell ^1\)-norm in each point. The result is a non-linear multiresolution method. The order of the operator is calculated. The stability of the schemes is ensured by using a special error control technique. Some numerical tests are performed comparing the new method with…
