Roman medicine in the legions

[sonic]

Hi,

I'm looking for information about Roman 'medics',
for example:
what value did the medicii have,
how did they work,
what kind of instruments,
the difference between urban and medicine in the army,
how did it evoluate and stuff.

I would be highly grateful because this will be used in my final paper for school

Have a look at Procopius' VI. ii. 13-27 for the remarkable accounts of the treatment of three injuries during the Gothic Wars in Italy.
