Through the Arabs the Galenical system found its way back again to western Europe.
In Italy, Bologna and Padua were earliest distinguished for medical studies - the former preserving more of the Galenical tradition, the latter being more progressive and Averroist.
This, like the earlier German works of the same kind (on which it was partly founded), contains both the traditional (Galenical) and the modern or chemical remedies.
The principle which mainly distinguished it was not merely the use of chemical medicines in addition to the traditional, or, as they were called in distinction, "Galenical" remedies, but a theory of pathology or causation of disease entirely different from the prevailing "humoral" pathology.
The remedies he employed were partly galenical, partly chemical.
