Rittertum

Dazu habe ich nur eines zu sagen: Von Don Quijote de la Mancha sagte man, er habe so viele Bücher über das Rittertum gelesen, dass sein Gehirn verdorrt sei.

I have just one more thing to say. Of Don Quixote of la Mancha it was said that he had read so many books on chivalry that his brain had dried up.
