The L'Orologio Eucaristico – for the supply of consecrated elements, i.e. Hosts and consecrated bread – was used to mark the date of supplying the Hosts. It was made before 1783, as indicated by the episcopal visitation record. Due to the small number of preserved examples of this type of objects, the L'Orologio Eucaristico of Czulice is a unique example of "Renovatio Sanctissimi Sacramenti".
