small portions of Zaliznyak's texts have been peer-reviewed to this time, as no research team came forward that was willing to learn and repeat the process over the length of a large text. Linguist Izabel Vallotton of Geneva cooperated with Zaliznyak on some portions of the reconstruction, where Zaliznyak identified a portion of the chain and passed it on to Vallotton, with both of them then continuing to independently reconstruct the text. In the experiment, both Vallotton and Zaliznyak ended up with completely identical chains, matching to the letter, but the chains were admittedly short, only 20-30 symbols long. Finally, a problem Zaliznyak considers unsolvable is identifying spelling errors or Russisms in the Church Slavonic. Often, the position where an error or deviation from Church Slavonic is possible, a correct symbol or symbols will also be present alongside an erroneous one, in which case Zaliznyak always assumes the original text was correctly written. In some cases, such assumptions will of course be incorrect. These multiple possibilities may also be the original author's correcting himself by erasing a mistake with his stylus and writing in a correct symbol. Concealed texts and identity of the owner One of the first concealed texts reconstructed was an unnamed text Zaliznyak called Instruction on Forgiveness of Sins. Its introduction is written in first person by somebody who identifies himself as 'Alexander, the Areopagite of Thracia, of Laodicean origins (birth)'. The text contains a highly unorthodox prayer, reading 'we pray to thee father Alexander, forgive us our sins by your will and give us salvation and the food of paradise, amen'. In it, this Alexander therefore assumes powers usually reserved to God alone. The prayer is followed by prophecies by the same Alexander, who then calls for people to 'leave your villages and homes' and to walk the earth, spreading Alexander's message. Alexander then says 'whoever listens to me, listens to Peter'. This is followed by a highly original call following along the lines of 'leave your villages and homes', with dozens of phrases starting with 'leave your' and listing a great number of things to leave, all starting with a Slavic prefix 'raz-': разлады, раздоры, расклады, развозы, распловы, разлогы, разлеты, размеры, размолвы, and so on (troubles, strifes, positions, moving around, sailing, flying, sizes, disagreements, etc.). This highly original sequence leads Zaliznyak to believe that the text was originally composed in Church Slavonic, as it is
