The Novgorod Codex ((ロシア語:Новгородский кодекс)) is the oldest book of the Rus’, unearthed on July 13, 2000 in Novgorod. It is a palimpsest consisting of three bound wooden tablets containing four pages filled with wax, on which its former owner wrote down dozens, probably hundreds of texts during two or three decades, each time wiping out the preceding text. According to the data obtained by stratigraphy (and dendrochronology), carbon dating and from the text itself (where the year 999 occurs several times), the wax codex was used in the first quarter of the 11th century and maybe even in the last years of the 10th century. It is therefore older than the Ostromir Gospels, the earliest precisely dated East Slavic book. == Discovery and description == Since 1932 the ancient Russian city of Novgorod has been continuously excavated by the Novgorod Archaeological Expedition started by Artemiy Artsikhovsky. Since the early 1970s the excavations focused on the Troitza (Trinity) area of the ancient Ludin part of town, covering nearly 6,000 square meters (64,500 square feet). The area excavated housed affluent mansions and a large 1,200 square meter (13,000 sq ft) communal building housed a court house and a Novgorod city treasury. The vast majority of text found in Novgorod were birch bark manuscripts; wax tablets were extremely uncommon. On July 13, 2000, the expedition headed by prof. Valentin Yanin discovered three wooden wax tablets in the soil. The tablets were 19 x 15 x 1 cm, and they have a 15 x 11.5 cm indentation filled with wax. Two of the tablets have one wax layer and one blank wooden side, and a third tablet has two wax sides. The boards have round holes at one edge, through which wooden pegs were inserted, holding the tablets together as a four-page book.〔 The tablets were discovered in a stratum 50 cm away and 30 cm below a wooden walkway dendrochronologically dated to the year 1036. As the strata in Novgorod are estimated to have grown at about 1 cm per year, the document was estimated to have been placed there around 1015-1020. Subsequent radiocarbon dating of the wax at the Uppsala University in Sweden gave the range of 760 AD to 1030 AD with a 95.4% certainty. Due to the Christian text on the tablets, dates earlier than the Christianization of Kievan Rus' in 988 are considered unlikely, and as such, the wax tablets are reliably dated to a very narrow 42-year window between 988 and 1030 AD. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Novgorod Codex」の詳細全文を読む スポンサード リンク
