Italian Influence in a Portuguese Mannerist Painting (Part I): A New Palette wi...
P. Melo, Helena; Valadas, Sara; Cruz, António João; Cardoso, Ana Margarida; Miguel, Catarina; Manhita, Ana; Helvaci, Yiğit ZaferThe palette used by the Portuguese painter Pedro Nunes (1586–1637) in the large panel depicting The Descent from the Cross (460 × 304 cm) painted in 1620 for Évora’s cathedral was investigated with a combination of the visual inspection of the paint surface and the analysis of the paint layers with microscopic, spectroscopic, and chromatographic techniques. Green earth and an orange artificial arsenic sulphide,...
Marcadores moleculares subrogados a la repelencia al agua en suelos afectados p...
Jiménez-Morillo, Nicasio T.; Almendros, Gonzalo; Guiomar, Nuno; Miller, Ana Z.; Barrocas-Dias, Cristina; de la Rosa, José M.; Hatcher, Patrick G.La repelencia al agua del suelo (RAS) se atribuye a la acumulación de compuestos hidrofóbicos (lípidos), pero su extracción no siempre elimina la RAS, lo que sugiere que componentes macromoleculares no extraíbles también pueden estar relacionados con una RAS. Se han estudiado suelos quemados (B) y control (UB) del Parque Nacional de Doñana (Huelva, España) bajo dos tipos de vegetación (alcornoque y brezo) y fra...
Bone stable isotope data of the Late Roman population (4th–7th centuries CE) fr...
Fernández-Martínez, Paula; Maurer, Anne-France; Jiménez-Morillo, Nicasio T.; Botella, Miguel; Lopez, Belen; Barrocas-Dias, CristinaThe aim of this study is to examine the diet, using bone stable isotope analysis (δ13C and δ15N), of a Late Roman population (4th–7th centuries CE) from the Roman villa of Mondragones (Granada, Spain). This archaeological site presents an exceptionally high number (n = 121) of well-preserved skeletal remains (adults and non-adults), giving the opportunity to study for the first time the nutritional and health c...
Combination of Stable Isotope Analysis and Chemometrics to Discriminate Geoclim...
Jiménez-Morillo, Nicasio T.; Palma, Vera; Garcia, Raquel; Barrocas-Dias, Cristina; Cabrita, Maria J.The knowledge of the isotopic composition of virgin olive oil (VOO) allows the evaluation of authenticity and geographical origin, being an important tool against fraud. This study aimed to assess if VOOs produced in three Mediterranean regions could be discriminated on the basis of multivariate statistical analysis of geoclimatic and isotopic data. A total of 138 geo-referenced VOO samples from Portugal, Franc...
Behind the Light – Specificities of the Materialities of a 16th Century Illumin...
Miguel, Catarina; Jacobs, Whitney; Ferreira, Teresa; Barrocas-Dias, CristinaThis work focuses on the material characterization of a sixteenth century illuminated antiphonary housed in the Biblioteca Pública de Évora (BPE) the Manizola 116c. Based on several optical and spectroscopic techniques, namely optical microscopy (OM),scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDS),micro-Fourier transform infrared spectroscopy ( -FTIR), Fibre-Optic Reflec...

Unveiling the underprintings of a late-fifteenth-early-sixteenth century illumi...
Miguel, Catarina; Bottura, Silvia; Ferreira, Teresa; Conde, Antónia Fialho; Barrocas-Dias, Cristina; Candeias, AntónioFor the first time, IR reflectography was used for analysing the production technique of incunabula, unveil- ing impressive results concerning the identification of underprintings and the relation with its coloured illuminated representations. In this work, the procedures followed for producing a late-fifteenth-early- sixteenth century incunabulum produced in the Parisian workshop of Germain Hardouyn held by th...
Effect of different healing stages on stable isotope ratios in skeletal lesions
Curto, Ana; Mahoney, Patrick; Maurer, Anne-France; Barrocas-Dias, Cristina; Fernandes, Teresa; Fahy, GeraldineAbstract Introduction: Physiological stress is one of the various factors that can have an impact on stable isotope ratios. However, its effect on bone collagen stable isotope ratios is still not fully understood. This study aims to build on previous research on how different disease stages may affect bone collagen stable isotope ratios. Materials and Methods: Carbon (δ13C) and nitrogen (δ15N) isotope ratios we...
Diet and disease in Tomar, Portugal: Comparing stable carbon and nitrogen isoto...
Curto, Ana; Mahoney, Patrick; Maurer, Anne-France; Barrocas-Dias, Cristina; Fernandes, Teresa; Fahy, GeraldineObjectives: This study explored the correspondence between stable isotope ratios and indicators of non-specific (periostitis and/or osteomyelitis) and specific (venereal syphilis) disease in a sample of human skeletons from a Portuguese archaeological collection. Additionally, this study examined stable carbon (δ13C) and nitrogen (δ15N) isotope ratios between individuals at different disease stages. Materials a...
Did military orders influence the general population diet? Stable isotope analy...
Curto, Ana; Maurer, Anne-France; Barrocas-Dias, Cristina; Mahoney, Patrick; Fernandes, Teresa; Fahy, GeraldineThis study integrates bone collagen stable isotope data (carbon, nitrogen and sulphur) from 33 human adult tibiae (15 females; 18 males) and 13 faunal remains from Tomar, while it was under the Military Orders domain (eleventh–seventeenth centuries). Historical literature indicates that the amount of meat consumption amongst Templars was lower than in individuals with similar social status. In Medieval times, t...
