In today’s #thread, we are going to talk about the first scientific analyses of the pigments employed on the mural paintings of @pompeii_sites, published by Jean-Antoine Chaptal (1809). Jean-Antoine Chaptal Pigment pots found at the Archaeological Park of Pompeii. Chaptal was lucky enough to receive 7 pigment samples found at @pompeii_sites from Joséphine de Beauharnais, Napoleon’s wife, Empress of France, and Queen of Italy in 1809.

En el #hilo de hoy vamos a hablar de los primeros análisis científicos de los pigmentos de las pinturas murales de @pompeii_sites, llevados a cabo por Jean-Antoine Chaptal (1809). Jean-Antoine Chaptal Pigmentos del Parque Arqueológico de Pompeya. En este #hilo @RestauraAraba nos habla también de este y otros científicos del s. XIX que se interesaron por el análisis del patrimonio cultural.

In today’s @thread we will be zooming in on the mural paintings of @Pompeii_sites, thanks to grazing light pictures and close-up photographs.

🎓📸Ph.D. Thesis Eduardo J. Millán Sañudo (University of Seville). Sacrifice of Iphigenia, House of the Tragic Poet (Regio VI, Villa de P. Fannius Synistor, Boscoreale Fresco painting was the predominant painting technique at @pompeii_sites. It is based on the application of water-dispersed pigment on wet plaster. However, as we will explain in today’s #thread, some decorations were executed using a different technique.

Hoy os invito a hacer zoom en las pinturas murales de @pompeii_sites a través de fotografías de luz rasante y detalles que nunca pensasteis que podríais ver tan de cerca.

Fannius Synistor, Boscoreale (MANN) Parece probable que la técnica predominante en @pompeii_sites fuera la pintura al fresco, que conlleva el trabajo sobre un mortero de cal húmedo. Sin embargo, como veremos en este #hilo, parte de las decoraciones se realizaron con una técnica diferente.

In today’s #thread we are going to talk about the manufacturing process and use of black pigments in Roman mural paintings, with examples from @pompeii_sites and @MNR_museo. Let’s go! Original Pompeian pigments ...XRF Analysis of a black bac... Pliny and Vitruvius considered black (called atramentum) an artificial colour, because it required the transformation of raw materials. However, according to Pliny, it could also be found in salt-pits or sulfurous earths, and some painters used to dig up charred human bones. Naturalis Historia, Pliny. ...De Architectura, Vitruvius....

You all know that Mount Vesuvius eruption covered and sealed @pompeii_sites, Herculaneum and the surrounding villas in 79 AD. But, what if I could tell you that volcanic ash and pumice could be playing a role in the deterioration of the fascinating mural paintings of the area? The volcanic eruption froze the daily life of these cities, what allows us to study the archaeological remains of a vibrant area, in contrast with other sites that were purposefully abandoned.

Todos sabéis que la erupción del Vesubio en el 79 d.C. cubrió y protegió Pompeya, Herculano y las villas circundantes. ¿Y si os digo que esos materiales volcánicos también juegan un papel en el deterioro de sus pinturas murales? La erupción detuvo en el tiempo estas ciudades, conservándolas en un momento de plena actividad, a diferencia de otros yacimientos arqueológicos que fueron abandonados y que conocemos ya sin vida en su interior.

The Villa Romana del Casale (IV century AD, Sicily), belonged to a member of the Roman senatorial aristocracy, probably an “Urbi Praefectus” (governor of Rome). The exceptional richness of its mosaics allowed the inscription of the Villa in the World Heritage List in 1997. The vestibule is open to a large peristyle, whose mosaic floor presents a series of animal protomes (lions, bears, tigers, wild boars and panthers) inserted in laurel wreaths, which reverse their direction on the western side, indicating the presence of two different routes.

Today we are going to talk about the variety of pigments and mixtures employed to obtain green hues from Ptolemaic and Roman Egypt to the mural paintings of @pompeii_sites, with a glimpse of the Macedonian tombs at Vergina and the Tomb of the Diver at @paestumparco. Pompeian pots containing pigments (@Mannapoli).Green pigment preserved in a Pompeian pot (Applied Research Several mixtures and green pigments have been detected in Ancient Egypt artefacts. Among the pigments, we can list malachite (Cu2CO3(OH)2), chrysocolla ((Cu, Al)2H2SiO5(OH)4·nH2O), Egyptian Green (CaCuSi4O10) and green earth (hydrated iron potassium silicates). Malachite.

In today’s #thread we will be talking about Late Classical and Hellenistic painting techniques, from Greece and Macedon to present-day Bulgaria and Italy. Aren’t these Tyrian purple backgrounds from Tomb III (Aghios Athanassios) and the Amazon sarcophagus just stunning? Head of Medusa, Tomb III (Aghios Athanassios). Source: httpsAmazon sarcophagus: battle scene. Conserved at the Archaeolo There are two main painting techniques associated to Late Classical and Hellenistic art: secco, which makes use of a binding medium to fix the pigments, and fresco, which is based on the application of the pigments on a fresh lime plaster.

Today we are going to talk about the pink hues in mural paintings from @pompeii_sites. As we will see, their chemical characteristics make it difficult to be analysed in-situ. To overcome this, the pigments conserved at the Applied Research Laboratory have been of great help. Bowl containing a pink pigment, conserved at the Applied Research Laboratory (Archaeological Park of Pompeii). This pink tone is to be found in certain examples at the Archaeological Park, frequently associated to the depiction of Venus, as in this painting of the House of the Venus in the Shell (Regio II, 3, 3).
