A very useful link to a translation of the work of Celsus-of whom so little is known, it may be that he transcribed/translated a much earlier Greek work, it is not even known if he was a working physician.
The work is a useful summary of the Ancient Schools and the competing dogmas (dogmatic, methodic and empiric).
and here is a nice quote:
[Legamen ad versionem Latinam] "To treat pimples and spots and freckles is almost a waste of time, yet women cannot be torn away from caring from their looks".
