Las yeserías del patio del sol del real alcázar de sevilla: Caracterización y cronología

Abstract

This research involves an interdisciplinary study aimed at determining the origin of the Mudéjar plasterwork of the Patio of the Sun in the Royal Alcázar of Seville. A double methodology has been used involving, on one hand, a synthetic history based on the analysis and correlation of the graphic and historiographic documentation of this Patio and, on the other hand, a characterization of the plasterwork material using XRF, XRD, radiocarbon dating of vegetable fibres, and the gravimetric analysis of the water-insoluble residue. Combining the results from the chemical and mineralogical compositions and the percentage of insoluble residue performed on three plasterwork samples with different textures, from C-14 dating of one sample, and from historical and document sources has allowed us to identify and delimit the original Mudéjar zones from the 13th and 14th centuries from the areas restored in the 20th century.
