From the Academic Lecture of Zaliznyak on Beryastyan Letters:
The next series of texts is associated with the name of a Novgorod man named Yakim - the record holder in the number of grants he left to his offspring. In 2010, 15 grams were found written by Yakim’s hand. The previous lectures. He has a characteristic (very good) handwriting, impeccable household graphics. The most distinctive feature - instead of the digraph of ou he writes ou (and at the same time he has a mirror, the rarest feature). Not only that Yakim wrote 15 grams two years ago... (laughter in the hall) he wrote, of course, earlier, but only two years ago gave them to us - another 5 grams of his hand were found in excavations of past years, scattered around. Previously, they were considered examples of the manuscript of other writers. Thus, after the 2010 season, he was considered the author of 20 grams. Another 17 were found this year, and the total number of Yakima’s blocks reached a record mark of 37, adding what he has yet to “send.” Which he insisted on and threw his letters nearby. The center of irradiation of his activities was the expeditional toilet (see. previous lecture), not touched by the years of previous excavations. In total, 73 grammatics were found on the territory of the former toilet. It is a pity that we have already overtaken it on all four sides, and it has no fifth side.
