This is one of the most common forms of typeface and is, in fact, notable. The opposing form of typeface wherein the lines in the letters are broken up is known as black-letter. Antiqua type faces are modeled after antique Roman and Carolingian writing. Antiqua typefaces are those designed between about 1470 and 1600, specifically those by Nicolas Jenson and Aldine roman. Antiqua script is called old style, differentiated from modern styles by the more or less uniform thickness of all strokes and by slanted serifs.
