Rochester the King of Smut
There is also in the same drawer a collection of my Lord of Rochester's poems, written before his penitence, in a style I thought unfit to mix with my other books. However pray let it remain there; for as he is past writing any more so bad in one sense, so I despair of any man surviving him to write so good in another.

Samuel Pepys' diary, 1680 

Rochester..., from the corruptions of that court, in which he lived, seems to have thrown off all regard to shame and decency.

David Hume, Of the Rise and Progress of the Arts and Sciences, 1742 

In many discourses with [Rochester] I saw into the depths of Satan.

Bishop Gilbert Burnet, History of my own Time, 1724
