The article is devoted to the research of the French medieval manuscript Legendarium, which began in 2018. The manuscript is written in the XIII–XIV century on parchment, perhaps on the territories coinciding and bordering with modern Belgium. With the exception of the names of several owners — King of France Charles V, Duke of Burgundy Philip the Good and Count K. K. Palen (the last owner) — the history of the manuscript is almost unknown. The book suffered seriously in the XX century from

All restoration work has been completed currently, the manuscript is kept in a unplait form, each individual sheet is enclosed in a special envelope from olyethylene terephthalate, sealed on three sides. Joint work is carried out by a group of researchers from SPbSU and Library of the Russian Academy of Sciences. The work includes an optical-photographic study using the visible luminescence method excited in the 300–400 nm range. The flakes of the surface layer, extracted from the preservation envelopes, which contain the sheets of parchment was used for the study. The amount and composition of the flakes make it possible to assess the degree of preservation of the manuscript and the expediency of its storage in an encapsulated form. Investigations by vibrational spectroscopy technique (Raman, FTIR) allow to understand the composition of the parchment, ink and pigments used in the manuscript. Non-corroborating manuscript studies provide an opportunity to develop new ways to possible reconstruction of lost more than half text elements and images of the manuscript. А number of results have been already obtained, which suggests that it is possible to isolate several "layers" of chemical compounds of different origin. Some of them are modern to the time of the manuscript creation, others parts are synchronous to several stages of restoration work.
