A small devotional pamphlet includes three pages of prayers and was printed for the believers for St. Gertrude's day, in November 1740 in Zagreb, Croatia.
Not much is known about the printer and publisher Ivan Krstitelj (Johann Baptista) Weitz (? – died in Zagreb, 1751). Born somewhere in the Habsburg countries, Weitz traveled through Carinthia and Carniola, and eventually moved to Zagreb in 1729, where he took over a press of a widow of Ivan Bartolomej Pallas (Johannes Bartholomeus Pallas). By the late 1930s he was working in connection with the Pauline and Jesuit monastery in Zagreb and later started making his own independent publications.
After Weitz’s death in 1751 his widow was running the business for two years and after that the publishing house was run by his heirs.
