Casanova Translated: History of my life ... by Willard R. Trask, 1968, vol. 3, p. 164. (Book 3, chapter 9, in Paris)
Casanova had lunch at Lady Mary Lambert (c.1717-1762)
After dinner the conversation turns to the rhinoceros which was being shown at the fair at Saint-Germain for 24 sous a head. ‘Let us go see it, let us go see it!’ We get into a carriage, stop at the fair, and take several turns through the walks, looking for the one in which the rhinoceros was. I was the only man, I had a lady on either arm, the intelligent Marquise was preceding us. At the end of the walk where we had been told the animal was, its master was sitting at the gate to take their money from people who wished to go in. It is true that he was dressed in African costume, enormously fat, and looked like a monster; but the Marquise ought at least to have recognised that he was a man. Not a bit of it.
'Are you the rhinoceros, Monsieur?'
'Step in, Madame, step in.'
She sees us choking with laughter, and, seeing the real rhinoceros, she feels obliged to apologize to the African, assuring him that she had never in her life seen a rhinoceros and so he must not be offended if she had made a mistake.
