Joris-Karl Huysmans,
The Cathedral — Chapter XIV
“ We need not dwell on the bull, the bison and the buffalo; the symbolists regard them as emblems of brute force and pride; while the goat and boar-pig are vessels of lust and filth.They divide this honour with the toad, an unclean reptile; the habitation of the Devil, who assumes its form to show himself to the female saints—for instance to Saint Theresa. As to the hapless frog it is equally defamed because of its likeness to the toad. ”
