The Mineralogy Manuscript Preserved in the Archivo General de Palacio, (Madrid, Spain): A Case Study

The manuscript of the Mineralogical lessons for the 1824–1825 course being held at the Royal Cabinet of Natural History had been found in the Archivo General de Palacio (AGP; Madrid, Spain) by the priest Donato García, who replaced Christian Herrgen and held the chair of Mineralogy until 1853. The historic document increases the scant record of this type of documentary source from a period still little known in relation to the state of Mineralogy teaching and allows for a closer understanding of this discipline. This article presents a thorough analysis to identify the collaboration between Professor García and his pupil, José Musso y Valiente, as well as the authorship of the manuscript in connection with the notes of this pupil, due to the absence of any indication in the historical document, with the objective of producing a mineralogy work on mineralogy in the Spanish language. To this end, the manuscript has been examined and compared with the Mineralogy notes of José Musso Pérez-Valiente, Donato García’s pupil, which are preserved in the Lorca Municipal Archive (Murcia, Spain). By comparing Musso’s notes with the manuscript from the Archivo General de Palacio, the idea is reinforced that the former were corrected by Donato García, who eventually left a copy in the Royal Library, corresponding to the one preserved in the AGP, constituting the first record of Donato García’s authorship in relation to Mineralogy.
