Rubrication was one of several steps in the medieval process of manuscript making. Practitioners of rubrication, so-called rubricators or rubrishers, were specialized scribes who received text from the manuscript's original scribe and supplemented it with additional text in red ink for emphasis. The term rubrication comes from the Latin rubrico, "to color red".
The practice usually entailed the addition of red headings to mark the end of one section of text and the beginning of another. Such headings were sometimes used to introduce the subject of the following section or to declare its purpose and function. Rubrication was used so often in this regard that the term rubric was commonly used as a generic term for headers of any type or color, though it technically referred only to headers to which red ink had been added. In liturgical books such as missals, red may also be used to give the actions to be performed by the celebrant or others, leaving the texts to be read in black. Important feasts in liturgical calendars were also often rubricated, and rubrication can indicate how scribes viewed the importance of different parts of their text.
Rubrication may also be used to emphasize the starting character of a canto or other division of text; this was often important because manuscripts often consist of multiple works in a single bound volume. This particular type of rubrication is similar to flourishing, wherein red ink is used to style a leading character with artistic loops and swirls. However, this process is far less elaborate than illumination, in which detailed pictures are incorporated into the manuscript often set in thin sheets of gold to give the appearance of light within the text.
Quite commonly the manuscript's initial scribe would provide notes to the rubricator in the form of annotations made in the margins of the text. Such notes were effectively indications to "rubricate here" or "add rubric". In many other cases, the initial scribe also held the position of rubricator, and so he applied rubrication as needed without the use of annotations. This is important, as a scribe's annotations to the rubricator can be used along with codicology to establish a manuscript's history, or provenance.
Later medieval practitioners extended the practice of rubrication to include the use of other colors of ink besides red. Most often, alternative colors included blue and green. After the introduction of movable type printing, readers continued to expect rubrication, which might be done by hand, if there were few rubrics to add, or by a separate print using a red-ink form, later the normal method. The "great majority of incunables did not issue from the press in a finished state… hardly any incunable was considered 'finished' by its printer…", suggesting that hand rubrication provided a sense of legitimacy to the efforts of early printers and their works. This fact, the notion that something about hand written rubrication completes a printed work by attributing to it a sense of legitimacy and finality, is further supported by the fact that red ink "was not merely decorative… red's original function was to articulate the text by indicating such parts as headings that were so essential to the function of manuscripts that the printers had to deal with them in some way".
The title "generally was written in one or more lines that the scribe of the text had left blank to receive the title", showing both the importance of the section and the knowledge one may gain from this process. As mentioned above, the initial scribe of a text often left notes for the rubricator of where rubrication would be necessary, a fact that helps the modern historian learn of the provenance of the manuscript. Rubrication affected how later generations read and interpreted a text, and this process helped ensure editorial standardization throughout Western Europe.
To prepare white-flake, get some sheets of lead beaten out thin, place them dry in a hollow piece of wood and pour in some warm vinegar or urine to cover them. Then, after a month, take off the cover and remove whatever white there is, and again replace it as at first. When you have a sufficient amount and you wish to make red lead from it, grind this flake-white on a stone without water, then put it in two or three new pots and place it over a burning fire. You have a slender curved iron rod, fitted at one end in a wooden handle and broad at the top, and with this you can stir and mix this flake-white from time to time. You do this for a long time until the red lead becomes visible.
