In 1776, the convent of Elizabethan Nuns in Prague’s New Town was commemorating the fiftieth anniversary of two events: the profession of the former Mother Superior M. Deodata a Presentatione B. V. Mariae OSE (née Anna Justina von Klausniz) and the laying of the foundation stone of the convent building. The celebrations of this dual anniversary were also reflected in the institution’s musical life. There was a performance at the convent of a congratulatory cantata with a libretto by the ex-Jesuit Rochus Elinger, and music was composed for it by the local choirmaster M. Juliana a Septem BB. Patribus OSE. On Holy Saturday, there was a performance of the sepolcro Der verlorne Sohn (The Prodigal Son), composed by Emilián Rickert OCist. from the monastery in Zbraslav. That same year, Jáchym Štěpanovský, the cantor from České Budějovice, also dedicated his works to the Mother Superior.
