Father Zadok Barącz, a Dominican of Armenian origin, undertook a lot of research on the Armenians and their history in Poland at that time. His merit lies in the fact that he published sources that he had previously classified and written down in a very personal way. In particular, his writings coincide with the chronicle of the monastery of Armenian nuns in Lviv, which is now lost. The text of the chronicle was indeed "trimmed", but it is likely that the main information was not changed. With this reservation, the chronicle sheds some light on the history of the monastery before the Archbishops of Lviv reorganized it and incorporated it into the Roman Church. The character of Sister Rypsyma Spendowska, an Armenian who was then a prioress, "experienced these changes, just like the Benedictine nuns of the Latin rite." Rarącz's writings constitute a picturesque background for the lives of those nuns who took the name Benedictine nuns of the Armenian rite. The changes affected, among others, the cult building of this small community. The chronicle presents nuns at various levels of the hierarchy, reflecting their monastic life, but also their openness to their compatriots and the cathedral, the clergy and the archbishop, as well as to events in the city and the country, not to mention epidemics, fires and wars. Barącz was particularly interested in Armenians in Poland before the partitions of 1771-1772. He used the chronicle mainly in this period, because for the later period, dating back to the mid-19th century, its text is too laconic to reconstruct the history of the Armenian Benedictine nuns of Lviv on its basis. They ran a school for girls at this time, and this second period requires examining other sources for additional information about their history.
