Background:
Ex voto is a donation for a divinity, a Saint or to Virgin Mary for a received mercy. From the analysis of an ex voto it's possible to obtain lots of information and therefore it can be used as a tool for health and epidemiological surveillance, to study morbidity in the past. The aim of this study was the creation of a database to rebuild epidemiological events and diseases, using ex voto as a source of health surveillance.
Methods:
We chose to study votive pictures using three types of sources: photographed alive, on-line archives, books and photographic collections. Ex voto have been saved in an Hard Disk, numbered and inserted in a database, then analyzed using Stata®.
Results:
total of 6231 ex voto were collected and catalogued in our database. Ex voto referring to diseases are the most represented (41%), but they have decreased with the time. Road accidents (21.4%) have a constant increase, especially with the appearance of cars and motorcycles. Aggressions (5.45%) decrease constantly; warlike accidents (4.44%) had a peak in the period including both world wars; non professional accidents (10.60%) and accidents at work (3.79%) increase without peaks; maritime accidents (8.88%) have not uniform ups and downs during the time.
Conclusions:
The database let us rebuild epidemiological events of the past, which are not deductible from other sources. Our purpose is to expand in the space-time our source data in order to perform an interesting comparison between past and present.
