A
rubric is a word or section of text that is traditionally written or printed in
red ink for emphasis. The word derives from the , meaning
red ochre or red
chalk, and originates in
Medieval illuminated manuscripts from the 13th century or earlier. In these, red letters were used to highlight initial capitals (particularly of
psalms), section headings and names of religious significance, a practice known as
rubrication, which was a separate stage in the production of a
manuscript.
