The term “Roman” is customarily used to describe serif typefaces of the early Italian Renaissance period. More recently, the term has also come to denote the upright style of typefaces, as opposed to the word “Italic”, which refers to cursive typefaces inspired by the handwriting of Italian humanists. Thus Linotype offers fonts called Sabon Greek Roman and Sabon Greek Italic, (designed by Jan Tchichold), based on 16th century models. But by using terminology which is typically associated with Latin type and evokes the history of Italian typography, Linotype makes a careless statement. “Greek Roman” and “Greek Italic” are contradictions in terms, mixing two very different histories.

Huh. Now that you mention it, yes, that sounds stupid.
