The D地i also referred repeatedly to what can best be translated as "the Art". Similar to our understanding of skill and art, the D地i "Art" was used to refer to a writer痴 mastery of the Skill. It was also commonly used to describe the general ability of the D地i to write these Books.
Great writers (only a few of whom have thus far been discovered) were said to have had mastered the Art. Early D地i manuscripts seem to imply that the Art was reserved only for the D地i bloodline, although lively D地i debates have been documented regarding the subject.
