The best proof of how thorough was the medical education at Salerno and
how much influence it exerted even over public opinion is to be found in
the regulation of the practice of medicine, which soon began, and the
insistence upon proper training before permission to practise medicine
was granted. The medical school at Salerno early came to be a recognized
institution in the kingdom of the Two Sicilies, representing a definite
standard of medical training. It is easy to understand that the
attraction which Salerno possessed for patients soon also brought to the
neighborhood a number of irregular physicians, travelling quacks, and
charlatans. Wealthy patients were coming from all over the world to be
treated at Salerno. Many of them doubtless were sufferers from incurable
diseases and nothing could be done for them. Often they would be quite
unable to return to their homes and would be surely unwilling to give up
all hope if anybody promised them anything of relief. There was a rich
field for the irregular, and of course, as always, he came. Salerno had
already shown what a good standard of medical education should be, and
it is not surprising, then, that the legal authorities in this part of
the country proceeded to the enforcement of legal regulations demanding
the attainment of this standard, in order that unfit and unworthy
physicians might not practise medicine to their own benefit but to the
detriment of the patients.

Accordingly, as early as the year 1140, King Ruggiero (Roger) of the Two
Sicilies promulgated the law: "Whoever from this time forth desires to
practise medicine must present himself before our officials and judges,
and be subject to their decision. Anyone audacious enough to neglect
this shall be punished by imprisonment and confiscation of goods. This
decree has for its object the protection of the subjects of our kingdom
from the dangers arising from the ignorance of practitioners."

Just about a century later the Emperor Frederick II, the Hohenstaufen,
in the year 1240, extended this law, emphasized it, and brought it
particularly into connection with the great medical school of the Two
Sicilies, of which territory he was the ruler. This law has often been
proclaimed as due to his personality rather than to his times,--as
representing his very modern spirit and his progressive way of looking
at things. There is no doubt that certain personal elements for which he
should be given due credit
