Multielemental analysis of tissues from Cangrande della Scala, Prince of Verona, in the 14th century.
Cangrande della Scala, Prince of Verona (Italy), died suddenly shortly after his triumph in the battle of Treviso (July 18, 1329). Thus, in the frame of a multidisciplinary paleo-pathological study, we carried out a multielemental analysis on the Prince's tissue specimens, including hair, liver, muscle, and bone, in order to characterize a multitissue profile of metallic elements in a nobleman of the 14th century. Biological specimens were analyzed by inductively coupled plasma-mass spectrometry. We were able to rule out arsenic poisoning as the primary cause of death. High levels of gold and silver in both hair and liver samples were probably due to prolonged contact of the mummy with precious metals in the funeral garments. High lead concentrations in both liver and bone tissue can be traced back to the ingestion of contaminated food and alcoholic beverages. Most of the essential elements were in the normal range of values for contemporary living people. The low arsenic and chromium levels in the Prince's tissues as compared to modern people would be suggestive of raised concentrations of both the elements in the present era, which are likely due to industrial pollution.
