The fonds is very important for the research of the history of Jews in the times of the Dubrovnik Republic since it contains two volumes related to Didacus Pyrrhus. Volume no. 42 contains a transcript of Didacus's poem De Rhacusinae urbid laudibus Carmen from a book which had been printed in Florence in 1613. Volume no. 95 contains a transcript of a short debate on the life and work of Didacus Pyrrhus, entitled Della vita e degli scritti di Didaco Pirro, altrimenti detto Jacopo Flavio Eborense. The text was written by Tomo Krša, a Dubrovnik writer and translator (1782-1826) and it was published in 1826 in Florence in _Giornale arcadio di scienze, lettere ed arti (_vol. 32, 1826). This fonds also contained a volume entitled De Didacho Pirro, Appunti which has been long lost.
