New results in ancient Maya rituals researches: The study of human painted bones fragments from Calakmul archaeological site (Mexico)
2020
Abstract The funeral chambers of the ancient city of Calakmul (Mexico) and the individuals who were buried in them have brought in recent decades new knowledge about the beliefs and funeral customs of the pre-Hispanic Maya. Tombs and bodies were prepared as part of the rituals that should favor the return of ch'ulel to the Underworld, known as Xibalba by the ancient Maya. The ch'ulel is one of the two anemic entities that inhabit the individual, equivalent to our concept of the soul. Bodies preparation included coloured scented body ointments application, with a deep symbolic connotation and probably also a conservative purpose. The aim of this research was to characterize pigments and bind…
Nuevos datos sobre el uso de materia colorante durante el Neolítico antiguo en las comarcas centrales valencianas
2006
La caracterización mineralógica de materias colorantes procedentes de los yacimientos valencianos de la Cova de l'Or, la Cova de la Sarna y la Cova Fosca de la Vall d'Ebo demuestra el uso de dos tipos de materia colorante durante el Neolítico Antiguo: Hematites y Cinabrio. Las características y distribución geográfica de cada una de ellas nos remiten a dos estrategias distintas de obtención y. probablemente. de utilización de las mismas.
IDENTIFICATION, PROCESSING AND USE OF RED PIGMENTS (HEMATITE AND CINNABAR) IN THE VALENCIAN EARLY NEOLITHIC (SPAIN)
2012
The results of the first elemental and structural physicochemical analyses (SEM–EDX, TXRF, XRD, FTIR, GC and EDXRF) of Early Neolithic red pigment samples from the region of Valencia confirm one of the earliest uses of cinnabar (HgS) in Spain (5300 to 5000 cal bc). They also inform on the storage of massive quantities of hematite and the development of specific technologies of hematite-based paint production and use. The samples were recovered at the three most significant Early Neolithic sites of the Mediterranean coast of Spain: Cova de l'Or (Beniarres, Alacant), Cova de la Sarsa (Bocairent, Valencia) and Cova Fosca (Vall d'Ebo, Valencia), which together have provided the most important E…
Ocher and cinnabar in the argaric funerary record
2012
The known cases of Bronze Age Argaric stained skeletons found in the Southeast of the Iberian Peninsula, have been analysed. The various hypotheses proposed relating to the origin of these colorations have been evaluated in light of new data provided by SEM, XRD and RAMAN spectroscopic analysis carried out on five Argaric graves of Murcia and Alicante. The results have indicated the presence of ochre and cinnabar on some of the skeletons. Without discarding the possibility that both substances were used in dyeing fabrics, it is proposed that their main use was for face and body make-up, being higher the number of recorded cases on female skeletons compared to male.
Klimt artwork: red-pigment material investigation by backscattering Fe-57 Mössbauer spectroscopy, SEM and p-XRF
2017
Material tests were performed on a rediscovered Klimt-artwork "Trompetender Putto". We performed studies on the red colored spots, mainly taken from non-restored parts. MIMOS II Fe-57 Mossbauer spectroscopy (novelty in art-pigment analysis) mainly reveals haematite and crystallized goethite in red colors. Electron microscopy can identify various layers of the original and overpainting of an artwork. The number of layers fluctuates between three and four chemically painted areas. The portable X-ray fluorescence analysis enables to reduce the pigment list to containing mercury (cinnabar), lead, zinc, iron and titanium. Infrared-light-irradiation visualizes the different age of the pigments.
Cinnabar phase in ZnSe at high pressure
2001
We have performed an energy-dispersive x-ray-diffraction experiment on ${\mathrm{ZnSe}}_{1\ensuremath{-}x}{\mathrm{Te}}_{x}$ alloys under high pressure with $x=0,$ 0.05, 0.1, and 0.2. In the downstroke a hexagonal phase appears. We suggest that this phase is cinnabar, whose stability range decreases as the Te content is reduced. The analysis of the whole series of compositions enables us to establish its lattice parameters in ZnSe $(a=3.785\AA{}$ and $c=8.844\AA{}$ at 10.5 GPa). The extinction of some diffraction peaks also suggests that the internal parameters u and $v$ are close to 0.5, indicating that the cinnabar phase in ZnSe is similar to that observed in GaAs and ZnTe.
Observation of the Cinnabar Phase in ZnSe at High Pressure
2002
In this paper we describe the results of an energy dispersive X-ray diffraction experiment carried out in the ZnSe 1 m x Te x alloy and pure ZnSe under high pressure. In the downstroke the cinnabar phase is observed between the rocksalt and the zincblende phases. The analysis of the whole series of compositions ( x =0, 0.05, 0.1 and 0.2) enables us to establish its lattice parameters in ZnSe ( a =3.785 + and c =8.844 + at 10.5 GPa). The X-ray diffraction pattern simulation suggests that the internal parameters u and v are close to 0.5, indicating that the cinnabar phase in ZnSe is similar to that observed in GaAs and ZnTe. The cinnabar's stability range decreases as the Te content is reduce…
The Contribution of Microchemical Analyses and Diagnostic Imaging to the Conservation and Identification of the Degraded Surfaces of Hellenistic-Roma…
2020
The Archaeological Museum of Palermo (Sicily) has recently presented the results of the restoration of three wall paintings from the House of the Masks of Solunto archaeological site. These significant paintings, dating back to the first century BCE, are the most significant examples of Pompeian style discovered in Sicily to date. The cycle of frescoes unearthed is the best preserved and most complete example of wall painting dating to the Republican Roman period in Sicily. This house was a luxurious private residence built on two floors and centred around a peristyle. This fresco cycle embellished the walls of a banquet room (oecus) discovered during an archaeological excavation carried ou…
Multianalytical characterization of pigments from funerary artefacts belongs to the Chupicuaro Culture (Western Mexico): Oldest Maya blue and cinnaba…
2019
Abstract The colours used in Pre-Hispanic Mesoamerica to decorate walls, codices or artefacts have been the subject of numerous studies, with particular attention to Maya blue, red and white pigments. However, most of these studies have been focused on emblematic cultures of the Classic period (ca. 300–1000 CE), such as Teotihuacan and Maya cultures. This work proposes a new chronology of the preparation and use of these pigments, particularly Maya blue, by analysing samples of the Pre-Classic period (ca. 1800 BCE–300 CE). The samples belong to ceremonial artefacts decorated with blue, red and white pigments, in a funerary context from the Chupicuaro culture, which was developed between 600…
High-Pressure Raman Study of Zincblende, Cinnabar, and Cmcm Phases Of ZnTe
2002
Raman measurements of ZnTe have been performed at pressures up to 15 GPa. Frequencies, line widths, and intensities of first- and second-order Raman features of the zincblende phase (0-9.5 GPa) were studied in detail. In this note, we focus on the Raman spectra of the high-pressure cinnabar and Cmcm phases. In the transition regime from cinnabar to Cmcm (12.2 to 13.7 GPa) the Raman data indicate the possible existence of a new intermediate high-pressure phase.
