She was the favourite mistress of the Duke of Wurtemburg in 1757.

She was a most charming woman.

The last time I saw her she was in Venice, and she died two years afterwards.

Her husband, Michel de l'Agata, poisoned himself a short time after her death.
One day we had all three dined with him, and after dinner the senator left us, as was his wont, to enjoy his siesta; the little Gardela, having a dancing lesson to take, went away soon after him, and I found myself alone with Therese, whom I rather admired, although I had never made love to her.

We were sitting down at a table very near each other, with our backs to the door of the room in which we thought our patron fast asleep, and somehow or other we took a fancy to examine into the difference of conformation between a girl and a boy; but at the most interesting part of our study a violent blow on my shoulders from a stick, followed by another, and which would have been itself followed by many more if I had not ran away, compelled us to abandon our interesting investigation unfinished.
