In 1959, an outstanding Russian specialist in the Coptic studies, E., issued two catalogues of the main Coptic collections of the U.S.S.R.: those of the State Museum of Fine Arts named after A.S. Pushkin (Moscow), and of the State Hermitage (Leningrad). In the first case, he published a complete corpus of texts; in the second one, a part formerly belonged to Ac. N.P. Likhachev only. The Likhachev’s Collection included papyri of a comparatively late period. With rare exceptions, there were legal documents, the analyses of which broadened our understanding of the Coptic onomastics, dialectology, terminology, etc.
For the history of religion, a number of documents written by monks or describing some peculiarities of the monastic life and the structure of monasteries are of special importance. We should mention also texts on the legal relations between the monks and laic people. So, the text 10 of the Coptic Collection of the State Hermitage (KTGE 10) tells us about some laic people who had taken a duty to work for the sake of a monastery – obviously, for the shelter, food and protection.
