THE MEDICI CHILDREN (FLORENCE, XVI-XVII CENTURIES): ANTHROPOLOGICAL STUDY AND PROPOSAL OF IDENTIFICATION.

Exploration of the Medici chapels in San Lorenzo in Florence revealed the burials of nine infantile members of the Medici family. Eight children were found in the intact tomb of the last Grand Duke Giangastone (1671- 1737). The crypt contained several small coffins collapsed to the floor or randomly spread over a raised plank, as a result of the disastrous flood of the Arno river in 1966, which partly upset the tomb and left a layer of dry mould. The children's remains, mostly skeletonised, were found inside the coffins or scattered on the floor or on the plank, probably transported by the water. Another child was exhumed from the chapel of Grand Duke Ferdinand I (1549-1609) and Cristina from Lorena (1565-1636). The infantile remains were submitted to anthropological study, which allowed to establish the number of individuals buried in the crypt, and to estimate the age at death. The anthropological results were compared with information provided by archival documents, related to members of the family who died in infantile age. An identification of the children is proposed.

A possible case of Garre's sclerosing osteomyelitis from Medieval Tuscany (11th-12th centuries).

Archaeological excavations carried out at the castle of Monte di Croce near Florence brought to light a small cemetery complex belonging to the castle church, dated back to the 11th-12th centuries. An elite stone tomb contained the skeletal remains of a male aged 35-45 years with obvious pathology of the right tibia. The proximal metaphysis and the upper half of the diaphysis appear massively enlarged as a result of severe chronic periostitis. A transverse section illustrates complete obliteration of the medullary cavity by new spongy bone, with some large cavitations. The primary, but completely remodeled tibial shaft is still recognizable. This finding and the strong sclerotic reaction with some central cavitations rule out any form of bone tumor and indicate a chronic inflammatory disease. The morphological and radiological picture and the tibial localization suggest a diagnosis of chronic sclerosing osteomyelitis of Garré, a rare form of chronic osteomyelitis characterized by an intense periosteal reaction with little or no suppuration.

Diffuse idiopathic skeletal hyperostosis in the Medici, Grand Dukes of Florence (XVI century).

Diffuse idiopathic skeletal hyperostosis (DISH) is a common systemic disorder characterised by the ossification of the anterior longitudinal spinal ligament involving at least three contiguous vertebrae and by diffuse extraspinal enthesopathies. The condition is associated with the male sex and with advanced age; its aetiology is uncertain, but seems to be related to obesity and diabetes. The most recent studies in archaeological series demonstrated a relation between high social status and the incidence of DISH. The present study examines two cases of DISH found amongst the members of the Medici family buried in the Basilica of San Lorenzo in Florence. The skeletons of the Grand Dukes Cosimo I (1519-1574) and his son Ferdinand I (1549-1609) showed the typical features of the condition. This result is related to the obesity of the Grand Dukes, attested by the written and artistic sources, and to the protein-based alimentation demonstrated by a paleonutritional study, thus furnishing further evidence to the significance of DISH as a life style.

The 'gout' of the Medici, Grand Dukes of Florence: a palaeopathological study.

OBJECTIVE: According to the written sources several members of the famous Medici family of Renaissance Florence suffered from an arthritic disease, called 'gout' by contemporary physicians; a palaeopathological study allowed verification of the true nature of the 'gout of the Medici' referred by archive document data. METHODS: The skeletal remains of the Grand Dukes and their families, buried in the Basilica of San Lorenzo in Florence, were examined macroscopically and submitted to X-ray investigation. RESULTS: Out of 15 investigated individuals, two cases of diffuse idiopathic skeletal hyperostosis (DISH), with ossification of the anterior longitudinal ligament and massive hyperostotic changes of the extra-spinal ligaments, were detected in the skeletons of the Grand Dukes Cosimo I (1519-74) and his son Ferdinand I (1549-1609). The left foot of Ferdinand also revealed typical lesions of the uratic gout, confirming the archive data, which describe the disease in detail. CONCLUSIONS: The association between DISH and elite status, highlighted in recent research, receives further confirmation in the present study, furnishing evidence to the significance of this disorder as a lifestyle indicator, linked specifically with a high-caloric diet, consequent obesity and type II diabetes mellitus. Furthermore, the coexistence between DISH and gout observed in Ferdinand represents the first documentation of this association in the palaeopathological literature.

The Medici Project first anthropological and paleopathological results of the exploration of the Medici tombs in Florence.

Within the framework of the Medici Project, a paleopathological team of experts from the University of Pisa, the University of Florence and the Superintendence for Florentine Museums, is carrying out a study on 49 tombs of some of the Medici family members (16th-18th centuries) housed in the so-called Basilica of San Lorenzo in Florence. The project involves disciplines such as paleopathology, funerary archeology, physical anthropology, paleonutrition, parasitology, histology, histochemistry, immuno-histochemistry, electron microscopy, molecular biology, and identification of ancient pathogens. The most recent biomedical imaging technologies have been employed to obtain as much information as possible about the genetic make-up, eating habits, life styles and diseases of these important rulers of Renaissance Florence. The first anthropological and paleopathological results are presented here.
