Genji Monogatari Emaki
The word "emaki" stems from the word "emakimono" meaning "picture scrolls". The emakimono picture scrolls consisted of two designs: Pictures that were painted on a scroll with text added to the same scroll or a number of paintings that accompanied passages of text and were joined together in a scroll. The first known picture scroll was produced in Japan during the late ninth or tenth century. The "Genji Monogatari" picture scroll, however, was produced in the early twelfth century. Not only is the "Genji Monogatari Emaki" the oldest surviving monogatari scroll but it is also the oldest surviving non-Buddhist scroll in Japan. There is no exact date to the scroll, but it is estimated to being sometime between 1120 and 1140, in which case it was created just a little over a century after Murasaki Shikibu wrote "The Tale of Genji".
Iron gall ink
The earliest recipes for oak gall ink come from Pliny the Elder, and are vague at best. Many famous and important manuscripts have been written using ferrous oak gall ink, including the Codex Sinaiticus, the oldest, most complete Bible currently known to exist, thought to be written in the middle of the fourth century. Due to the ease of making iron gall ink and its quality of permanence and water resistance this ink became the favored one for scribes in the European corridor as well as around the Mediterranean Sea. Surviving manuscripts from the Middle Ages as well as the Renaissance bear this out as the vast majority are written using iron gall ink, the balance being written using lamp black or carbon black inks. Many drawings by Leonardo da Vinci were made with iron gall ink. Laws were enacted in Great Britain and France specifying the content of iron gall ink for all royal and legal records to ensure permanence in this time period as well.
