In reading an article concerning the authorship of De Doctrina Christiana -- some people think that someone other than John Milton wrote it -- I came across the following, in a list of people who were researching this issue: "David Holmes (West of England, Bristol), a stylometrician whose reputation has been built on authorship attribution studies ..."

Stylometrician? One presumes that this is a person who compares the style of the questioned work with the style of known works of the author to reach a conclusion. New one on me!
