The cultural revival in Salerno was linked to Benedictine monasticism,
with its main center at Montecassino. Historical evidence of the acti
vity of the Salerno School of Medicine dates back to the 10th century,
though the most productive period of the Salerno masters was in the 1
1th-13th centuries. The school's knowledge was broadened in the 12th c
entury by the work of Constantinus Africanus, who translated many clas
sical texts from Arabic into Latin. Circa Instans, a fundamental text
on medicinal botany, was also produced by Mattaeus Platearius. Towards
the middle of the 12th century, the school gradually became a theoret
ical center, rather than a primarily practical one, and many commentar
ies on earlier texts were produced. Uroscopy was pre-eminent in the te
achings of Salerno, which was also one of the first medical centers to
recognize the contribution of surgery to treatment. The precepts of t
he school were widely disseminated by the Regimen Sanitatis Salernitan
um, which contained remedies for every occasion and advice on keeping
healthy.
