From the Pepys diary feed, 19 December 1664:
Going to bed betimes last night we waked betimes, and from our people’s being forced to take the key to go out to light a candle, I was very angry and begun to find fault with my wife for not commanding her servants as she ought. Thereupon she giving me some cross answer I did strike her over her left eye such a blow as the poor wretch did cry out and was in great pain, but yet her spirit was such as to endeavour to bite and scratch me. But I coying -[stroking or caressing]- with her made her leave crying, and sent for butter and parsley, and friends presently one with another, and I up, vexed at my heart to think what I had done, for she was forced to lay a poultice or something to her eye all day, and is black, and the people of the house observed it.
