I remember, the players have often mentioned it as an honor to Shakespeare, that in his writing (whatsoever he penned) he never blotted out a line. My answer hath been, would he had blotted a thousand. — Ben Jonson

Unlike Shakespeare, Jonson was known as a slow, meticulous writer. After Shakespeare’s death, Jonson wrote: “I remember the players have often mentioned it as an honor to Shakespeare that in his writing, whatsoever he penned, he never blotted out a line. My answer hath been, would he had blotted a thousand. [...] I loved the man and do honor his memory on this side of idolatry, as much as any: he was indeed honest, and of an open and free nature; had an excellent phantasy, brave notions, and gentle expressions; wherein he flowed with that facility, that sometimes it was necessary he should be stopped.”
