In reference to a production of All Mistaken, or The mad couple on 28th December 1667, Samuel Pepys noted:
“I rose soon from dinner, and with my wife and girle to the King’s house, and there saw “The Mad Couple,” which is but an ordinary play; but only Nell’s and Hart’s mad parts are most excellently done, but especially hers: which makes it a miracle to me to think how ill she do any serious part, as, the other day, just like a fool or changeling; and, in a mad part, do beyond all imitation almost. [It pleased us mightily to see the natural affection of a poor woman, the mother of one of the children brought on the stage: the child crying, she by force got upon the stage, and took up her child and carried it away off of the stage from Hart.] Many fine faces here to-day.”
