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 Latin: rubrica, 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, section headings and names of religious significance, a practice known as rubrication, which was a separate stage in the production of a manuscript.

An illuminated manuscript is a formally prepared document where the text is decorated with flourishes such as borders and miniature illustrations. Often used in the Roman Catholic Church for prayers and liturgical books such as psalters and courtly literature, the practice continued into secular texts from the 13th century onward and typically include proclamations, enrolled bills, laws, charters, inventories, and deeds.
