reliably dated to a very narrow 42-year window between 988 and 1030 AD. Basic text The wax of the codex itself contains psalms 75 and 76 (and a small fragment of psalm 67). This is the so-called basic text of the Novgorod Codex. Consequently, the book is alternatively known as the Novgorod Psalter. This text can be read as easily as any other document on parchment and could be examined at once. The Psalter translation exhibits a somewhat different translatory tradition than the Slavonic translations of the Psalter known so far (especially the Psalterium Sinaiticum). Language The language of the Novgorod Codex is a very regular (especially in the basic text) Church Slavonic, albeit with some 'mistakes' in the rendition of the yus letters betraying the author's East Slavic origin. The whole text was written by the same hand in a so-called 'monoyeric' orthography (Russian одноеровая система письма), i.e. instead of the two yer letters ь and ъ only ъ is used; before the codex discovery, the monoyeric system was considered to have been a late invention, with the dualyeric system being the original; the discovery proved that the reverse was the case. Preservation and reading method Preservation of the tablets presented unique challenges, as the usual preservation method for wood would have destroyed the wax layer, and vice versa. The method eventually decided on called for careful separation of the wax layer, and preserving each material separately. The newly exposed wood under the removed wax was found to have been extensively scratched by the stylus cutting through the thin wax. It took the research team several weeks to realize that some symbols could be discerned in the scratches. Russian linguist Andrey Zaliznyak, one of the foremost experts on the early medieval Novgorod dialect, has taken tremendous effort to reconstruct so far only a small portion of the texts preceding the basic text. The main difficulty with this task is the fact that the feeble traces of dozens of thousands of letters left by the stylus, often hardly discernible from the natural shading of the soft lime wood, have been superimposed on each other, producing an impenetrable labyrinth of lines (Zaliznyak speaks of a “hyper-palimpsest”). Consequently, ‘reading’ a single concealed text of one page can take weeks. According to Zaliznyak, reading the concealed texts in the scratches is a unique challenge unlike anything attempted by any research team previously. The
