A treatment of the script with red ink, or script written in red ink to set off initials, headings, or instructions. Rubrication provides guidance to the reader by indicating the start of sentences, sections, major words, or even entire texts that are to kept separate from the main text. Rubrication may include the use of red slashes through initials or red underlining, as well as texts copied in red (e.g., instructions in liturgical texts that are not to be read aloud during religious services).
