[from Walsh] The earliest written records of Rus seem to date from the 11th century. The most authoritative, complete and earliest of the Chronicles to have survived is The Lavrentyesky Spisok, dating from 1377 and so called after the Monk Lawrence who copied it, The second oldest is called Ipatsky Spisok, after the Ipatsky Monastery where it was found. The main part of both these Chronicles is an historical compilation, "The Tale of By-gone Years" which was long thought to be the work of the Monk Nestor and was known as The Chronicle of Nestor. It is now generally held to be a compilation of the work of many men.
