Castellar is a capital letter typeface from John Peters, named after a location in the Alps. It first appeared in 1957 with Monotype. Peters modelled the design on the Roman script Scriptura Quadrata as it was used in the first two centuries of the Roman Empire. One distinguishing characteristic is the quadratic proportions of many letters, which are however mixed with circular and narrow forms. The original script was called Scriptura Quadrata because the ancient engravers used rectangular stone plates for their work. Castellar is a typical title typeface and is best used in large and very large point sizes to highlight its classic elegance.
