end of the 16th century the text of the Code was divided into 100 chapters (or "Sto glav" in Russian), and had become commonly referred to as the Stoglav. Accordingly, since these times the Sobor acquired the name "Stoglav Synod". The Stoglav was the basic code of canon law as well as a guide to the everyday life of the Muscovite clergy. There are many hand-written editions of the "Stoglav".
