	[About] Rus writing. One person, whom I rely, told me that one of the kings of Mount Kabk (Caucasus) sent him to the king of the Rus; he claimed that they had writings, carved on wood. He showed me a piece of white wood, on which were images, I do not know whether they were words, or individual letters, like this.

	Previously, the Slavs did not have books, but they used lines and notches to tell fortunes, being pagans. After being baptized, they tried to write down the Slavic language without changes in Roman and Greek letters...

	"Rus" is a state concept, not an ethnic one.
