They died suddenly in 1494 and their deaths have been for centuries a subject of debate. The exhumation of their remains offered the opportunity to study the cause of their death through a multidisciplinary research project. Anthropological analyses, together with documentary evidences, radiocarbon dating and ancient DNA analysis supported the identification of the remains attributed to Pico. Macroscopic examination did not reveal paleopathological lesions or signs related to syphilis. Heavy metals analysis, carried out on bones and mummified tissues, showed that in Pico's remains there were potentially lethal levels of arsenic, supporting the philosopher's poisoning theory reported by documentary sources. The arsenic concentrations obtained from analysis of Poliziano's remains, are probably more related to an As chronic exposure or diagenetic processes rather than poisoning.", "keywords": ["Male", "Microscopy", "Spectrum Analysis", "Environmental Exposure", "Mummies", "06 humanities and the arts", "Bone and Bones", "Arsenic", "Forensic Toxicology", "03 medical and health sciences", "0302 clinical medicine", "Italy", "Arsenic Poisoning", "Microscopy", " Electron", " Scanning", "Humans", "0601 history and archaeology", "Carbon Radioisotopes", "Ancient DNA; Angelo Poliziano; Arsenic poisoning; Girolamo benivieni; Pico della Mirandola; Radiocarbon dating", "DNA", " Ancient", "History", " 15th Century"]}, "links": [{"href": "https://doi.org/10.1016/j.jflm.2018.03.016"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Journal%20of%20Forensic%20and%20Legal%20Medicine", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1016/j.jflm.2018.03.016", "name": "item", "description": "10.1016/j.jflm.2018.03.016", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1016/j.jflm.2018.03.016"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2018-05-01T00:00:00Z"}}, {"id": "10.1017/rdc.2018.62", "type": "Feature", "geometry": null, "properties": {"updated": "2026-07-27T16:17:52Z", "type": "Journal Article", "created": "2018-07-19", "title": "Molecular Fingerprinting of14C Dated Soil Organic Matter Fractions from Archaeological Settings in NW Spain", "description": "Abstract

This paper evaluates the complexities of radiocarbon (14C) dates from soil organic matter (SOM) in archaeological scenarios. The aqueous NaOH-insoluble residual SOM from Neolithic to medieval sites in NW Spain produced consistently older calibrated14C ages than NaOH-extractable SOM. Using pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) and thermally assisted hydrolysis and methylation (THM-GC-MS), we analyzed the molecular composition of these SOM fractions, aiming to understand the differences in14C ages and to gain insight on SOM dynamics in relation to age fractionation. The molecular composition of the NaOH-extractable SOM, which accounts for roughly two-thirds of total SOM, has a larger proportion of microbial detritus than the NaOH-insoluble SOM. This might suggest that the discrepancies between the two fractions is due to microbial rejuvenation in the extractable fraction, leading to14C results that are younger than the activity that is to be dated. However, archaeological evidence presented here unambiguously shows that the14C age of the extractable SOM provides the more accurate age for the targeted activity, and that the insoluble fraction contains inherited old carbon. After statistical data evaluation using Partial Least Squares-Regression (PLS-R), it is concluded that this inherited SOM is a mixture of Black Carbon from wild and/or domestic fires and recalcitrant aliphatic SOM.This paper evaluates the complexities of radiocarbon (14C) dates from soil organic matter (SOM) in archaeological scenarios.
