Fanjeaux

Umberto Eco, in The Name of the Rose, describes, through the inquisitor, Bernard Gui, how Saint Dominic, preaching to the 'heretical' women of Fanjeaux, conjures up satan in the form of a 'frightful cat the size of a large dog, with huge, blazing eyes, a bloody tongue that came to its naval, a short tail straight in the air so that however the animal turned it displayed the evil of its behind...'
He then describes it springing up the tower 'leaving his stinking waste behind'

Bernard Gui stretches the whole 'cat' theme to account for the choice of name the 'Catharists' gave themselves.

Whenever I find myself in Fanjeaux I stand under the tower and think of Dominic (founder of the Domini Canes, the Lord's Dogs, ironically) and his rant and satan running up the tower in cat form, and feel very glad not to have been a Cathar woman.
