    La Espiral Cave (Cuba): Guano and signs of Plant Substances Used as Paint Ingredients
    (Springer Nature, 2017-05-22) Fernández, Racso; Morales, Dany; Mas Cornellá, Martí; Jorge, Alberto; Solís Delgado, Mónica; Parra, Enrique; Rodríguez, Dialvys
    At La Espiral cave, located in Bahia Honda municipality (Artemisa province, Cuba), there are several pictographs, including two of particular importance due to the design used: one of concentric circles and another of a spiral. We analyzed the pigments and binders used in one of these pictographs. The chemical ingredients of the paint are considered in this article, as well as the use of bat guano as a major pigment compound. The apparent presence of ellagic acid, ellagitannin, or anthocyanins would strengthen the hypothesis that artists used vegetable protein as a paint binder or solvent.

    Minateda rock shelters (Albacete) and post-palaeolithic art of the Mediterranean Basin in Spain: Pigments, surfaces and patinas
    (Elsevier, 2013-12) Mas Cornellá, Martí; Jorge, Alberto; Gavilán, Beatriz; Solís Delgado, Mónica; Parra, Enrique; Pérez, Pedro Pablo
    The inorganic and organic fractions of two microsamples of prehistoric paint from the same site, the Minateda rock shelters, are analysed here for the first time. The two samples correspond to two rock shelters of different styles (Levantine and schematic) e Abrigo Grande de Minateda (The Great Rock Shelter of Minateda) and Abrigo del Barranco de la Mortaja (Del Barranco de la Mortaja Rock Shelter). Since its discovery, historiographical tradition has emphasised the Abrigo Grande de Minateda, with its magnificence and complexity, as emblematic of the origin and evolution of rock art in the Mediterranean Basin of the Iberian Peninsula (a UNESCO World Heritage Site). Four complementary techniques eMicrophotography, Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy (SEM-EDX), Raman Spectroscopy and Gas ChromatographyeMass Spectroscopy (GCeMS)e were combined to identify and characterise the physicochemical properties of the paint and of the surface. We present an interpretation of the results that leads us to define complex taphonomic alterations beyond the usual distinction of layers that include the surface, pigments and patinas.

    Relative and Absolute Chronologies, Iconographic Sequences. Pigments and Pictorial Micro-Stratigraphies: Aouinet Azguer 1 Rock Paintings
    (Universidad Mohamed V, 2023-06-22) Mas Cornellá, Martí; Lemjidi, Abdelkhalek; Solís Delgado, Mónica; Maura, Rafael; Parra, Enrique; Pablo Pérez, Pedro; Jawhari, Tariq; Oumouss, Ahmed; Asmahri, El Mahfoud; Oulmakki, Naima; Torra, Guadalupe; Pérez, Javier; García, María; Maximiano Castillejo, Alfredo Miguel
    Aouinet Azguer 1 is one of the most representative painting rock shelters in Morocco due to the quantity and characteristics of the images on display, which were carried out over an extended time lapse. In Aouinet Azguer 1 and 12, we find some zoomorphous figures outlined in red whose composition, size, style and technique bear no relation to the rest of the motifs. These figures correspond to an early chronocultural first phase, they were painted choosing privileged or central positions and in most cases we are not able to identify them since, even if by their volumetric shape the images seem to follow a naturalist tendency, their execution is highly conventional. In this study, the AMS 14C dating was possible on an anthropomorph of the third phase also painted in red (3770 to 3650 Cal BC, minimum age), on the basis of a well-known technique (oxalates dating). These results were completed using a methodology that combines physicochemical and micro-stratigraphic analyses used to interpret this dating, which is difficult to get it. Considering the need to put in first place the preservation of the rock paintings under study we could not get another one. Furthermore, a meaningful number of questions arise related to dating and cultural relationship to the first pictorial phase which has been defined upon traditional archaeological criteria, which we intend to propose as our leading hypothesis, by means of the analysis of archaeological environment from the Atlantic area, proposing a probable date (Later Stone Age-Early Holocene).
