[Syphilis in sixteenth-century in Bologna. Health care and social assistance (Part one)].

Syphilis arrived in Bologna in the summer of 1495, after Fornovo's battle on the Taro where Charles VIII's army, following the invasion of Naples, fought against the anti-French league who faced up to the invaders as they withdrew. It was the battle-weary Bolognesi, prisoners, deserters and probably some prostitutes following the French and mercenary army who introduced the infection into the city. At the beginning of the syphilis epidemic, the disease was very aggressive with particularly visible symptoms and many resulting deaths. Subsequently, contemporaries mention an abatement of this aggressivity in time spans that varied, but in no cases exceeded 60 years. In 1507 Bologna lost its political autonomy, becoming dependent on Rome. This was symptomatic of the upheavals throughout Italy in the sixteenth century. In this situation of economic and institutional crisis the Bolognesi were able to react with decision to the epidemic, re-converting the municipal hospital dedicated to S. Maria dei Guarini during the sixteenth century. This hospital, specializing in treating syphilis, was called "Ospedale di San Giobbe". It was closed in 1798, after the entry of the French army into Bologna. In 1560 the Bolognesi, realising that the most important causes of the spread of syphilis were social degradation, prostitution and poverty, founded another institution for the poor and for the prevention of prostitution. This institution was developed by the Opera dei Mendicanti and provided hospitality during the 1590 famine, in a city of 55,000 inhabitants, for as many as 1400 poor and sick. We also present the cure (guaiac and mercury) that they used at the time against syphilis. In such a difficult historical period beset with political and economic problems, the Bolognesi established two important institutions and showed that social solidarity is a value for the whole population.
